I see lots of information on using Dawn Dish Soap mixed with water for cleaning. What step is it used and should that step be followed by wiping off with water?
the dawn keeps the water from evaporating quickly and leaving spots and its suggested since it leaves less residue that would need to be rinsed off. your final wipe with wax and grease remover will take care of anything that is left.
I mostly hear about it after the car is blasted, so I guess if you are sanding to bare metal it will do the same thing of taking the dust away and cleaning the steel.
Dawn dish soap is a versatile cleaner, we use a strong solution to wash incoming vehicles that have been recently detailed. Helps get rid of excess wax and silicone.
I wash everything with Dawn before doing any sanding or bodywork.
After priming and sanding the primer I wash it with it again,
just before paint. I see no reason for wax and grease remover after Dawn.
Haven't used W&G remover at all in the last 10 years.
The idea of washing before sanding, blasting or body work is to eliminate the chance of grinding contaminants into the metal.
One of the teachers at the local college had us use Tide Laundry detergent. Yes it cleaned great but was rough on the skin. Dawn seems to clean every bit as good but not so harsh.
I use it to wet sand with as well, like said before, it increases surface tension some and doesn't evaporate as easily. I use it in the same bottle that I use for working with my shrinking disc. Best hand cleaner I have found, I keep the pump type by both sinks.
