Q: Spraying the bottom of the car during car wash

asked by on May 16, 2016

Is it usable to spray underneath my car during the car wash with spray cleaner? Are there delicate components that shouldn't be exposed to pressure?

You are just spraying the bottom. The bottom itself doesn’t have any delicate stuff under there. Everything under there is sealed so you go ahead and spray under there, especially the area where you get a lot of salt in the Winter. The fanciest car wash actually sprays from the bottom to get the salt off.
