Remove & replace moldy shower caulk 

I’m a 22 year old female (living at home right now) with no experience in shower repairs or anything, but with this video I was able to reseal my shower and get the moldy old grout out. My dad was so impressed that he had me do the master bathroom for them, lol.

I’m a 75 year old man and I am so glad I tuned into this video before I began this project! Good work young man!

I do lots of these in my business. First start by removing all the soap scum off the walls. If you don't, that residue gets under the new caulk and it may not stick well. After removing the old caulk and cleaning, I spray Microban into all the joints to kill any remaining mold, and drying with a fan before installing caulk. Most Silicon caulks have a 30 min set time. I tell customers to wait overnight to use the shower.

I have spent 2 hours watching videos on caulking a shower.. Your video has been the best and most helpful by far. Thank you so much for your time and effort spent on this video! Much appreciation from Australia!

This is the best era to live in. All info on the net. Thanks ...updated My bathtub 🛁 seal came out great. I used painters blue tape around mine so it came off easy and very crisp/professional. I obtained that tip about tape from the comments. Thanks again.

Your video was the only video of the many i watched that even came close to preparing me for this big job. I was a first timer when I started but now feel like I can caulk like a pro!! I recaulked the whole shower, then dismantled, cleaned, recaulked and reassembled by whole framed shower by myself thanks to your careful instructions. I did develop my own little techniques as I went along, which is likely why everyone has their own expert opinions in the comments. But for a beginner this guy has the most realistic video and advice to be found.

So I am back with an update!! It came out beautiful!!! I am so happy and pleased. I hacve now moved on to your changing a light fixture video and will take a stab at that! Thanks!

Gold Star Award - the Best demo of removing old caulk and mold. And the cleaning before installing, Thank you

I'm now inspired and excited to do a previously dreaded project. People like you are what give me reason to love RU-vid!

Thank you so much for this tutorial video. Your tutorial gave me the confidence to be able to clean up our moldy shower. I bought all of the materials and was able to do this project all by myself! I was so proud - and so was my hubby (especially since he didn’t have to do any of the work 😂). Thanks again!!!

Thank you! I finally did it, after about eight years of intending to do it, during this rare rainy weekend here in Northern California. Your video was invaluable. I'm proud of the results.

Hello Australia, thanks for watching and for the feedback.

Caulk guns have a hole back by the handle. It is meant to be used to cut off the tip on the tube of caulk - insert the tip at an angle and squeeze the handle!

Your video prepared me with a shopping list for tools, clear step-by-step instructions, and gave me the confidence to do the job. I have no experience with this and it turned out great! I appreciate the time you took to teach us.

Good job. When I was removing the grimy silicone, I used some painters tape along the edges because no matter how hard you try you will make tiny scratches in the porcelain which then trap soap scum and you're back to a "mold" issue again.

Easily the best video i've seen on this process. You showed EVERY step. Thank you!!

we just bought a home and are fixing it up ourselves, we have to recaulk our bathub/shower, this video was really helpful. your shower looked great

I would recommend always cleaning with alcohol/Ethanol after scrubbing away the mould. Note also that you always apply the Silicon in the reverse direction to what his doing, that way their is no need to smooth out as it is done automatically i.e. you hold the tube the same way - yet push not pull. took me a few years to learn the right way! Yet gives great results.

thank you for sharing. New homeowner here - got a quote for $125 for my small shower. Nope, Ill try it myself. Your instructions are straightforward.

Thanks for taking the time to leave feedback.

I usually do not leave any comments but I just wanted to point out that with 100% silicone when caulking with it in showers and Tub surrounds you will find that your best bet for beginners is to use the tape method where you run masking tape along both sides of your joint fill it with silicone then finger it until it looks like you want then pull the tape off and then use soapy water to lightly smooth over any rough spots. I say this because when you smear silicone out on the edge of your joint really thin then let it dry and after a little while of use you wipe down your shower and those thin edges that got smeared out come lose easily and start to hold dirt and grime and that's how your caulking starts to look bad and mold and mildew start growing there. I know a thing or 20 about this because I have been fixing this problem for 27 years for customers. Mold and mildew are silicones kryptonite 100% silicone is awesome stuff but get a little mold n mildew under an edge and it starts

You've made your how-to-video a no-brainer! Thanks for making it to detailed and showing every step. It's time to tackle the grout in my shower, I guess. I'm going to check out more of your videos after this.

You did a beautiful job. Thanks for explaining each step so well.

I have felt so daunted by ~ and have avoided ~ this project ~ for a LONG time. and this was the weekend I committed to making it happen ~ this how-to video was SO helpful! Easy to understand and follow. And the caulk removal and installation is done! Thank you for sharing this fantastic resource!

Thank you so much for making this guide! Made it so easy for me to redo our shower, where the caulk had eroded so the shower leaked a bucket-load everytime we showered! Cheers!!!

This video is very helpful. I really appreciated how you described every step - even wiping the silicon on a paper towel. I've been avoiding this project too, and your video is really helpful

Thanks for the straightforward, no-nonsense tutorial

This is SO helpful! I hope this video stays up for a long time, or at least long enough for me to finally get my lazy butt psyched enough to try this.

Thx...gonna give this a try today. I've also been dreading doing this...

The five year old in me cannot stop snickering, but this is very helpful, as I'm about to do mine. Thank you, sir!

I bet your glad you did this chore 8 years ago. Lol. With 3.3M views it paid for itself. Good job and thank you !

Thanks so much for taking the time to share this, Kerry. It is very clearly explained. Now, off to the hardware store!

i made some mistakes the last time i tried this and now will try again. thanks for the step by step! very helpful

Great video, thanks! To anyone else who’s here to learn how to remove old caulk, save yourself a lot of time and effort and go get yourself the scraper he’s using at 1:40. You won’t regret it and they’re very cheap.

I did this a day ago, never done before but pretty much did what you showed. Thankfully. Thanks

I do mine once a year....you did a great job explaining how to... Just takes time to prep and time to do it right. Some people just use the caulk gun and run a bead...looks like crap!! You need to smooth it out. Follow this DIY vid and do it right !!! GOOD JOB

Perfect! Exactly the information I needed! Thanks so much for making it easy

Good videos on your channel. I just tackled the molded caulk in our shower. To more quickly and thoroughly remove the caulk remnants, I used a wire wheel brush attached to my drill. It creates some dust but it was much better than trying to remove it all by hand. Thin disposable nitrile gloves are the way to go in spreading the caulk. I placed a dehumidifier in my shower to remove all the moisture after the caulk was removed.

This was a great video. Love it. Right to the point and covered all I was looking for

super helpful! I had great success removing old caulk with your instruction. Thanks!

Thanks a lot for the video and practical tips. I got it done yesterday.

This is excellent and just so well done - very clear, focuses on the task at hand, explains the steps very well, and it just gets right to the point. Thank you so much for posting this! It is a huge help to so many of us who want to try to get our own work done, but have no experience with this. I am planning on re-caulking a bathroom, partly because it's long overdue, partly because I am noticing a growing ant problem in the bathroom, as it seems they have found ways to dig some kind of tunnel leading to gaps in the grout and caulking. I will also have to check other parts of the house to re-seal cracks and possibly re-paint as well. (I am wondering if I should try to remove some tiles in the bathroom to check for ant nests, but since I have to rely on my own, and can't afford a professional, I am not sure if it is worth the risk of creating a need for expensive repair.) Superb video!!!

Thanks. When I saw the moldy caulk in my shower, I was worried I was going to have to replace my entire bathroom. :). Your tutorial and calm demeanor put me at ease.

This was the most helpful video I've seen on this subject. The first time around, I didn't take the time to do the extra cleaning. I did it this time. Thanks!

removal process is a bit faster with a shopvac . it keeps the scraper from pushing in the old caulk and helps remove mold and gunk. i like to scrap with the vac right behind it so loose stuff is never in the way . Vacs also speed up dry time

It's a great job, but I want to say people now used epoxy tile grout to caulking the joints, it's different from traditional silicone sealant, it has advantages of waterproof, mildew proof, antimicrobial, easy to clean of the surface, and it will be same as ceramic after curing, but still have toughness, many colors can be selected to suit various tile or shower. Two-component epoxy tile grout is really a good partner for tile accessory.

Thank you for sharing this. You made it simple and easy to follow.

Thank you for posting! I now know I can do this myself...this weekend’s project :)

This is super helpful, thank you!

Thank you! Simple, effective instructions. You rock.

Wow you gave my the confidence to tackle this job. Thankyou so much.

Very good explanation on how to properly attempt a tricky job. This video helped me a lot. Thank you!

excellent and detailed video, thanks

Good video. Always satisfying to see new..cawlk ;)

Man, that’s some high quality work there. My caulk lines look awful.

Great upload. Straight to the point, no idle chat. Thanks

Thank you - I just finished mine today! it did help me a lot... My girlfriend will be happy! ;-) aahha Thanks again!

Took me around 4 hours to remove old caulk, clean up, and install the new caulk. New caulk needs 24 hours to dry before you get it wet.

Thanks for this great instructional video. I like that your audio was well in sync with the visuals (and delivered so very calmly). Perfect DIY guidance for laypersons like me.

Doing our tub this weekend and been dreading it but thanks 2 your EASY and CLEAR instructions I am READY 4 the task 👍🏼🐢👍🏼

Now you can tell your landlord you made the repair and request a rent reduction. :)

You have to remove the cleaning agents, residue with some sort of spirit, methylated spirit, acetone ....no worries

I followed the advice of the DIY store. He did say to use a sponge dipped in water to smooth the grout out but it was your tip of dipping the finger tip in the water that did it. My work is not bad for a first timer. THANKS a lot!!

Fantastic video. This is exactly what i was looking for, when removing and replacing moldy shower caulk.

Is it ok not to fill spaces with grout before using sealant? Also. I tried removing the caulk with a stanley knife but it was a stupid cheap plastic one. I cut below and above but wasn't able to get right to the surface so it left lots of caulk to get off. Spent well over an hour using a razor blade and a broken plastric rule as a small makeshift tool to remove it. It's hot and I'm sweating like a fool lol.

Thank you. I am a woman, and I want to do this by myself.. save my money on labour.

Great video again. I really like the simplicity of your projects. It works great for someone like me who's technically challenged.

I liked your video. You did a good job removing and installing a new sealant

Pro tip - if you’re a weekend DIYer , wear gloves as much as you can while any work

better tip for smoothing - wait 5-10 minute, deep your finger in a warm water with soap and smooth the silicon. This way nothing get sick to you finger.

Great video! Today I got super tired of my moldy caulk. I am going to tackle it with the tips from your video. I am super excited about my project and can't wait to start. Thanks!

I still cannot believe I did it. Looks so smooth and no leaks. After all these years finally I did it with your VIDEO. Super (((:))))

I didn't want to caulk over the existing caulk because it had mold in it.

It took less than one tube to do my shower.

you have the patience I do not have - god bless you - thanks for the vid

Thank you very much. You show us the great tricks to remove and clean the moldy silicone. I will try to do it this weekend per your instructions. Previously, I did not clean all the mold 100%; therefore, it came back so fast within a few months. This time, I will.

Another great tip but most wont take the time. Each time you shower squeegee the walls and then use a dry washcloth go over the walls and all the caulk lines. The dryer the better. We’ve been doing this in our bathrooms for 19 years- no mold whatsoever... never once. I remember as a kid with 6 kids and 3 adults there was always mold around the tub & shower. It was gross and no one cared.. lol There are only two in our home. It takes 3 minutes to dry the walls. Then you won’t have to do this every year.

Thank you. One suggestion: I would much prefer to see you using gloves when you're using the spray cleaner and especially the Clorox wipes. Bleach is hard on your skin and may be toxic. Why take the risk? Take care!

Very helpful! Simple and easy to understand. Thank you!

wow this is great tired of asking my landlord to do it ,i did not know how simple it is well u made it easy thank u love youtube.

What they don't tell you in these videos is to WEAR GLOVES. I taped mine off first. And when I pulled off the tape I got caulk all over my hands. It is nearly impossible to get it off! So wear gloves.

I prefer not to mix Clorox with other chemicals because I dont want to die.

Great video - simple, straight-forward and effective.

Thanks for taking the time to share this project.

What a pain in the cojones!!! When will there be a way to have seals without caulk? This way I could just wipe this stuff away without all the drama

I've yet to find a caulk that won't mold! All seems sales BS to me! lol

Good tips, thanks for posting. My caulk gun didn't have those features but most new ones I see do.

Excellent video, thanks for posting. Re-caulking my shower now. Good tips

Single Ladies, this is what we need men for...this and money for shopping.

One of the better videos I have seen on this topic

This was so helpful... easy to follow and it made the job so much easier. Thanks so much for posting.

I did IT. Yahoo! Your way went so smooth and fast. Looking swell.

Thanks iScaper 1. I have never worked with grout and hope I never have to in this lifetime. The caulk will be much easier. Thank you.

Thanks for the video - the straight edges were great to do but had trouble with my corners.

I’m about to attempt to do this for the first time ever and have been a little nervous about the process 😬 i came across your video and now that I’ve watched your process, I feel much more prepared to try it out - thanks so much for this helpful video and useful tips! 🙏

thanks so much! I'm going to do this tomorrow after school and surprise my parents :) can't wait for a clean bathtub!!!

The water on finger method alone has me subscribing..it helps so much blending or tapering.

Thanks for sharing. You took the mystery out of a very simple DIY project.

I'm going to be tackling this project in my shower this weekend. This has helped me out tremendously, there were some things that I didn't know about, that I do know now. Thanks for making a great video!

Thank you! I’m watching this to give myself the confidence to re-caulk my shower.
