How Often Should I Wash My Car? -- My Take 

How often do you feel its necessary to clean/wash/detail the exterior of your car?

For those of u who came here for an answer, the answer is: It depends.

Thanks a lot. Explained completely.

Before/After washing and detailing a car. I think it would be good idea to grab a paint depth gague to know where to add more coat.

I live in California and I have a black 2014 Toyota Camry and I use that thing everyday and especially in traffic and I usually get a lot of break dust.

Education by far my most expensive investment.

Strange. The other side of the coin is, never wash it. Unless you get bird poo or something acidic on it which will eat through your clear coat. I have considered this years living in a snow salt state, I've been undercoating. Meticulous with brushless car washes, hand washing. Still lost cars to rust, lost clear coats. Washing under the car heavily removes the undercoat (just applied undercoat to my truck today). Washing the top removes the dirt particles etc. But now your top clear coat is exposed to u.v. sun. Unless you plan on waxing it by hand every couple weeks with a good wax the u.v. sun will hurt the clear coat overtime. Almost seems a quick easy rinse under neath and on top to remove salt is the way to go. But not actually washing it. That removes undercoating. It doesn't matter if the cars dirty or not along as it's not actually against the metal. There are people that never even wash their cars that seemed to have better luck than me (who is pretty meticulous). Maybe just not washing it at all. Reapplying oil undercoat twice a year is the way to go. Yeah, it'll be dirty. But the necessary elements needed for rust won't be available to the under carriage. It'll be oil and dirt. Basically. Top of the car, the pollen, dirt, whatever might actually protect the clear coat from the suns rays. The clear coat on most cars is something like .004 thick? Dont remember. But everytime you scrub that thing its good to remember you are messing with, might even be removing a fractional amount of that clear coat. Sure, you can wax it, make it shiny. But that fraction of clear coat is forever gone. Eventually you'll have so little clear coat you'll have to wax and polish it. As there won't be any shine or any protection for the base coat. Lot to think about. Quick low pressure rinse and a spray sealer once or twice a year might be the way to go. Actually washing it. Might be the worst thing you can do. My girlfriends car is actually in better shape than mine (and she never washes it, maybe car wash once a year or two years). Myself. Meticulous. Have lost 2 cars to rust. Which i can only explain by washing removed the undercoatings. And washing hurt the clear coats. Considering this now as to where i have gone wrong. Another channel (guys a auto technician does undercoat/rust too) i was watching other day he basically says never wash your car. Just keep applying oil undercoat. It'll look dirty, but underneath it'll be fine. This is for snow/salt states. Basically these are the elements that are necessary to cause corrosion, rust, hurt the clear coat. Deprive science of those elements. Dont wash it. Just oil it. Bird droppings. Accidic maybe spot remove? But even then if the car is dirty enough. Like only gets slightly rinsed when it rains. The droppings still arent on the clear coat. Its on the dirt and scum on top of the clear coat. Not on the clear coat itself. The grime on it protects it from the sun too. Food for thinking.. Other thing.. If its that cold, the car can't rust anyway. Even salt has a minimum effective temperature. The stuff they put on the roads does. Granted pretty low but a minmum effective temperature. If it's ten degrees, probably too cold to rust. The warm says, humid near feeezing or above freezing days is when i (think?) rust could activate. Thats why people that use heated garages (i have one i dont use), this isn't necessarily good. You've covered the car in road salt driving. Then put it in high enough temperature it'll activate rust. Better to use the garage only when its warmer and more humid outside. If it's cold outside. Car probably better off outside. Rust requires air, oxygen to happen. Added is corrosive (road salt) which requires certain temperatures as well to activate. The suns rays beat down on the clear coat. Sealing from all of the above, with dirt, grime, oil, lanolin coatings. Seems scientifically logical. Deprive it of oxygen. Consider the dirt on the top the clear coats sunshade. Came here through inquiry "how often should you wash your car". Answer might be. Never. I've moved from spraying fluid film underneath to use crc marine ( salt water boat protecting it's anti salt). Haven't figured out what to put on the clear coat. Tempted to coat the entire truck (it's brand new) in a crc marine oil,wax. Washing regularly, been there done that. Didn't work. Thoughts?

It will be better if you put 5 or 6 scenarios and tell us, it depends is not the answer we are looking for

Wow, so many words...

So pretty much when someone wants to.

Maybe once a year if it's really dirty. Other that that, clean the lights and the windows if I can't see out of them due to road grime. Other than that there's no point as it just gets covered again. The Civic is 15 years old, used every day, 204k miles, never misses a beat and looks BETTER than most it's age. The only thing it gets on the dot is servicing. If it needs parts, it gets them.

Sorry I could not finish watching this video. This is too long for this topic. You need to get to the point right away. You’re losing your audience dude!

Mate you need to get to the point alot quicker. Stop waffling. Dude detailing has got to your head. Your a car washer not a doctor.
