I have a lot of power steering fluid under the RV due to leak in air to air charger. What can happen use that is safe to clean off underneath and some of the engine? Thank you in advance.
If you have access to a car wash that has an outside bay so you can wash your coach, simply using the high power sprayer on the underside of the engine will clean a lot off. However, a good shot of an engine degreaser would be even better. Then, all the residue can go down the drain, designed for grease and soap (at the car wash), and not hurt your yard, or stain your driveway at home.
