hey guys, i'm having a problem finding a chemical to use in car washing, we do a couple of auto auctions and its taking us too long to get the jod accomplish. I've heard of guys around my area using some type of touchless chemical to wash limos with out touching them just spraying soap and rinsing off with DI water. i do two steping in trucks but i wouldn't spray acid on a $ 90,000 vehicle. any suggestions ?

Those auctions I guess are HIGH end used cars huh and the trucks you wash are under the price range of 90,000.

Just make your 2-stepping little weaker and wash them,the big trucks has the same clear C as the 90,000 cars.

thank you for the assistance, about making the mix weaker but wouldn't it damage the glass and stainless metal on mercedez or BMWs. I dont just do expesive vehicles, the auctions we do are police impounds, i'll just like to move a little faster than brushing each single car. Here in Los Angeles everything its so comperative you have a mobile car wash almost on every other business, its hard when you have to compete weekenders.

Really I think your acid rain in your area would do more harm than a weak 2-step.Now days windsheilds are made more so for acid rain protection.Spraying it on a hot dry surface and letting it dry made burn SS,other than that I think you would be ok.I wash trailers with SS fronts and backs without doing any harm,however I have seen some trailers that look like they have been burnt by some type chemical or letting the chemical dry on a hot surface.Thats what I'm basing my judgement on what caused it to burn.They do make a cheaper SS on some trailers that even a strong saop will burn if applied to it hot and let it dry.

I wouldn't be afraid to try it on the BMW's,this would be a good time to learn flashing if do not already know how.

When In Doubt Think It Out

I dont know what is flashing, i never heard of it.

Unless you know 100% what you are doing when working with any type of acids why take a chance of ruining a vehicle unless you don't mind submitting claims to your insurance company. I have a extensive training program when working with all our different types of chemicals. If you do not have an idea if it will do more harm than good research it first then test drive it in the field. There are many products out there that claim to be this wonder wash but fall short. You will always walk this fine line between Quality and Productivity, choose your poison. assets your bottom line. I always try to have a detailed conversation with the client on what they expect and go from there. You wouldn't expect to purchase a Cadillac for Volkswagen prices. If there willing to pay for detailing then price it for detailing. But if they just want a soap and a rinse then put your brush away, afterall if the customer is happy your happy right? Good luck

Most drive-thru car washes operate on the two-step principle, but as has already been said, don't spray EITHER chemical on a hot surface. Cool the surface first, then apply chemical, then a good rinse.

i appreciate your assistance guys.
