Ospho Metal Treatment: Pure Metal Cleaning Magic! 

Advertise this to motorcyclists. Our headers can be seen and we like our rides clean.

please use STAINLESS steel wool so you won't impregnate the material with carbon steel that rusts instant

Matt, I know it has been a year now since the video, but "Oshpo" does work well on flash rust on many metals. The brand "Klean Strip" concrete and metal prep is much cheaper at under $18 per gallon and phosphoric acid is the active ingredient at 30-40% (Intellectual Properties) but Oshpo contains some wetting agents and other non-cleaning active agents. Wetting agents are not surfactant like soap. Soap like "Dawn" dish soap is a slight alkaline which stop or neutralizes acids activity. Use "0000" steel wool works but a gray or maroon Scotch-Brite work fine depending on desired finish on the metal. I am a repair tech, an ASE Master Tech since 1978, retired, doing my due diligence by researching products by results, cost, ease of use and results for cleaning metal prior to painting or if not seen but protected, spray with an automotive grade of Epoxy 1:1 mix sealer the blocks oxygen from forming or allowing more rust to form. The "Metal Prep" cleans surface rust just like your video, but is cost effective and since this restoration is for myself, I prefer maximum protection over a long time. Few look inside a door, metal inner fender or bedside on a truck, but I do. I bothers me knowing that 90% or rust perforation occurs from the inside out. While new metal is welded in to replace thin rusted metal, if the back of the weld is obstructed, no room for one's hand, cover a small detail paint gun w/PPG 2.0 cup system can spray epoxy upside down to run into pinch welds, behind structure, door skin folds, but simply by gravity and viscosity (10% Urethane reducer or 20%) will allow it to float in under air pressure currents & Eddie's will cover a great deal. Spray a cavity / frame wax into any area water will collect due to humidity and drops in temperature just making sure OEM drain holes are open with a wire or pick! I just prefer best practices to achieve an internal protection worthy of the external finish. DK, ASE master tech since 78, retired.

Everybody needs someone that looks at them like Matt looked at the Ospho 🤣😭

Great video. I have 2 suggestions: #1: When opening any container for a smell test, try waving your hand at the top of the opening to spread out the fumes before breathing. #2: sometimes 0000 steel wool is referred to as Four Ott. Example: One Ott, two Ott, three Ott and four Ott.

I can’t tell you how many hours I’ve spent watching Matt on here. I have NEVER seen him react like that to anything.

One word of advice to anyone that might use this on a surface that is to be painted later. You HAVE to rinse every last bit of Ospho off and dry the surface completely. If you don't, you will have paint adhesion issues later on.

The first I heard of this was when Scott (Dryceman) used it on the M3. After watching this I went out and got some (my hardware store had it) and used it on the stainless exhausts on my trucks...it works amazingly well. And that reax at 3:38. Priceless.

That looks so good Matt.

Unbelievable results! Definitely giving this a try. Interestingly phosphoric acid is what makes fizzy drinks tangy and it’s metal cleaning ability is why coke is used to clean old pennies.

Please wear eye protection. Remember this is phosphoric acid. Neutralize with water then towel dry.

Never have seen Matt that excited! :)

The whole time I am thinking, “Don’t get any on the Porsche!” I always move my cars away if I am going to use industrial chemicals. My version of obsessed.

Hey Matt, when I smoke ribs or what have you my stainless steel water pan turns that color brown and steel wool in warm soapy water does the trick it always amazes me how like new it is after I clean it. the ospho is definitely doing something as I have to scrub twice as hard as you to remove The discoloration maybe some APC will work for maintenance after the initial cleaning i’m definitely gonna pick some up when it hits the store have a good one

Nice to see him very happy

You can buy ospho at Home Depot, Ace Hardware.

You gotta use that reaction clip on the store page for this. Only the reaction part it would be hilarious

This is outrageous at how easy it's cleaning the metal

Seeing you get blown away by a product is not only rare, its hilarious haha

my dad showed me what ospho and phosphoric acid (stronger) can do when I was growing up, but I didn't really realize how great it was until I was trying to clean up rusty stuff for paint or new zinc plating during a resto. leave bolts in it over night and boom no rust anymore, or use it as shown in the video to scrub light rust off a surface. as some other commenters have noted however, you may want to cut it off the surface after use, otherwise it can continue to react to a lesser degree and can create white powdery residue and issues with paint adhesion.

Glad I stayed up tonight :)

I bought it after watching M3 video. I works so good

Holy mackerel. I need this for my duramax exhaust, badly!

I cleaned a full factory exhaust front to back in 20 minutes. Looks like new

You officially made the short list to be the next Slap Chop guy with that reaction

Matt you crack me up .... I want some of that!

Mac's Aluminum brightener for about 45 seconds. (No scrubbing needed) a good spray down with the power washer and it will look brand new. $13 bucks for a gallon @ Napa auto parts.

Wow! That’s great!

Great!. I've been using Ospho on a 83 Cub Cadet restore. The locals here in rural southern Georgia highly recommended it. Also on an old Sears and Roebuck garden trailer that amazingly hardly has any rust and built like a tank. Subscribed and enjoyed your video. One of the guys at the paint shop emphasized to make sure you rinse it all off with water or your paint can blister.

3:38 Life changing moment. Ever since I saw the dry ice video with the E36, I've been thinking I need to get some ospho. Not sure where to get it local though in Ontario.

What does Ospho do on cast iron? I'm looking for a finish for my cast iron bench

Almost feels like a Shamwow infomercial! Ha!

Holy crap, now that's satisfying.

Good God I need a bottle of this ASAP please !

Unbelievable amount of content

Meguiars wheel brightener works very well when used with steel wool

Tip, do some Green Star afterwards to neutralise the acids - and Mat, you can sell it like a package 😉 great work 👌

Ospho is very common. Any hardware store should have it and it should be very easy to become a reseller.

It's always fun cleaning up metals with acid! If you've never tried this, take a VERY rusty bolt or nut and dip it overnight in a cup with some muriatic acid poured in it. Might not even take the whole night, anyway you'll come back to a completely rust-free bolt. Acid etches the surface, so you're gonna wanna paint it ASAP after you rinse and dry off the bolt or whichever part you treated. I hope you flushed out that acid you sprayed inside the exhaust. Otherwise down the road you might (or whoever has the car by then lol) encounter a little hole in the exhaust from all that internal corrosion finally making it to the other side :P.

So if you could carry this in the store will you be able to ship this across the country and how do you guys deal with the hazmat issue of shipping???

How would you use this on a truck frame still attached to the truck.? So you're pretty much working above your head..... Thoughts ? I bought a used truck. It has some rust underneath. I wanted to make it last a little bit longer.

Matt is the happiest kid in the room when something just works Ha,ha...

Dont all stainless steel cleaners/rust removers work like this?

You can find this stuff anywhere. I’m sure I’ve seen it at Home Depot

That was very cool. Try it on other metals

We would by this stuff in 55-gal drums to clean the inside surfaces of our stainless and aluminum reactors (250-gal to 4500-gal). Orthophosphoric (acid) is the chemical name and it's used as a converter to phosphate from an oxide. I think I used to purchase it from Skybryte.

But can it core a apple?

lookup concrete and metal prep by Klean Strip bro. Same exact product at half the price. One gallon is $18.

That stuff is birth control at its best!

Aluminum brightener/acid heavily used in the Big rigs metal polishing industry... spray bottle are almost instantly damaged once you spray any acidic additives. I actually do custom metal polishing.

Old rust, pitting, only the surface oxidation is affected by Ospho. 1993 Truck Frame (Texas / no salt) Under hood, no engine, Rusty Cross member and Frame rails, Power steering pump side of engine bay, no rust at all, guess why... Pressure washer was initially required to expose metal, Battery side of truck, pressure washed as well, built up rust was treated with Ospho, No Go for paint, the built up rust layer had to be removed before painting, Angle grinder with brush required to finish the job, Ospho made this task much much easier. Re-treat with ospho. Because i have the weather, re pressure wash with water and dried in the Texas sun, Primer applied, Paint to be applied when that damn sun isn't overhead. (Rust-oleum Pro.)

Yeah you’re right it’s from the marine industry, I worked on hatch’s in Fort Lauderdale for 23 years & we usually used Awesome OSPHO on stainless steel rails & everything metal all the time….. you can either wipe off the excess or even rinse it with water because once it’s on there it itches the metal & can go straight to priming then paint….you’ll get to enjoy the smell ! Lol

I like how you say , " every time you get your car up in the air just wipe it down" like everyone is fortunate to have a lift in their garage!🤦🏻‍♂️😂

That was fun to watch. Fun starts at 3:34 people.

You can buy that stuff at any ACE hardware

Would this work on Titanium exhausts?

As others have said, stainless steel wool only on stainless steel. Otherwise your rust issues will return with a vengeance and combine with stress corrosion cracking.

😂 Haha that reaction 🤣

« It really doesn’t smell » (meanwhile Matt’s nose hairs have disintegrated).

can you use it on motorcycle headers?

Matt, Any eta on this being in the store?

First...lets go. Get this on the store Matt

PFM! Get me some of that.

Matty's money shot 3:35

On this episode of Obsessed Garage: Matt cleans a thing! Ole Matty is amazed by a cleaner! Matty might make a dollar selling a used part! 😅😅

awesome

It’s the steel wool. You’d get the same results with water. Old body shop secret. Your happiness when cleaning is unparalleled.

This is similar to "bar keepers friend" for your stainless steel cookware. That stuff is also magic in the kitchen lol.

I'm a retired painting contractor of 40 years, ospho is a product I kept on the vans. It's main purpose is to neutralize rust by chemically changing rust into a primer. One word of caution, don't get it on anything made of aluminum because it will permanently corrode it. You can buy it in gallons at any paint store or any of the big box stores. Also every painter in America has used ospho to treat rusted iron and steel.

If you are trying to smell something like that you should waft/wave it to your nose so you don’t get a lot of the vapors and possibly hurt yourself.

Quad zero steel wool.

"But wait........there's more"

Klean Strip Metal Prep. Same shit 1/2 the price.

About to take the exhaust off mh tesla and do this 😁

RIP iK sprayers

Perfect for cleaning up the nasty Weber grill.

I need it where can I get it

There’s nothing better than Matt shitting on something

wow

I see the results you are getting, but I am also reading this " Ospho chemical alters rust into a stable surface which looks black"

Douch zoom lol

👍

How long until Matt start cleaning undercarriages 🤣

Did you guys see Matt's 'O' face?

#0000

The only problem I see with this is the fact that its 45% orthophosphoric acid which means that your spray bottle will now be single use after this has passed through it!

Oh come on man, water/vinegar would have done the same thing. That is SURFACE rust and very LIGHT surface rust at that. That's no test for that product.

It is a Rust Treatment product...please treat it as such....

Ospho is diluted muriatic acid.....
