Foam Gun?

[RIDE3311]

Hey guys,

My parents got a couple of new cars this past weekend. I am getting ready to get a big order of stuff, like a Flex or PC and some goodies. Included in that order is going to be a foam gun. I'm not about to learn how to use a polisher on a new car, but I wanted to wash and apply Zaino to my parents cars. I have read that it is good to wash a car with liquid dawn to get any old wax or anything off the car before applying new sealants. My question is:

Is it safe to use Dawn wash soap in the foam gun?

Thanks,
Harshil

Dawn has a very high pH around 10 or 11. I would go with a soap one that AG has with the pH around 7 for your foam gun. The best way to remove wax from your paint IMO is a alcohol/DI 50/50 water mix wipe down...Dawn over time can be corrosive on rubber, metal and some plastics...

Thanks Sparkie! I only planned to use the Dawn on the first wash. Do you think that is even necessary? I was just going to get the DP Xtreme Foam Shampoo with the foam gun. Also could you clarify on what alcohol/DI is?

Thanks

Do you just mix it into a spray bottle and then spray on and wife off after you wash the car?

there is NO need to ever use Dawn liquid on cars ... if your going to use a paint cleanser , AIO, or polish they will remove any old wax or sealant.

Zaino hyped the use of Dawn many years ago to remove wax specifically. It wont even dent a well cured sealant. Problem is it can dry out your weatherstripping and rubber surrounds.
