I always use a quality car wash soap, and never use dish washing liquid. Dish washing liquid can remove wax and leave your car’s finish unprotected.

I always start at the top of the car and work my way down.

I prefer to use a wash mit, instead of a sponge, and make sure that I rinse the mit of any dirt, before I put it back into the bucket.

Work in small sections and rinse often to prevent the soap from drying onto the finish.

Always wash in a shady area when possible.

When done washing, chamoise to dry your car, but make sure whatever you use is clean, so you do not scratch
the finish.
