- Work in the shade if possible or wash early in the morning before the temperature gets too hot. A hot surface causes the wash and rinse water to evaporate too quickly increasing the likelihood of water spotting.
- Park on a slight incline to allow rinse water to run off moldings, trim, and recessed areas better.
- Wash tires & wheels first. If you clean the RV first, when you wash the wheels you’ll probably spatter cleaners, dirt and brake dust on already cleaned panels around the wheel wells.
- Start by thoroughly wetting the RV with a medium spray of water to remove loose grit and surface dirt.
- Wash from the top down and rinse the RV often. Frequent rinsing is especially important.
- Use a detergent specifically formulated for automotive or RV use. Follow the directions on the bottle for the proper mix ratio. Using too much soap is wasteful and may leave a soap residue on the surface.
- Most RVers use a scrub brush with an extension handle. You will want one with soft bristles and lots of them so the brush will hold lots of soapy water.
- Sheepskin wash mitts keep grit away from the surface and should last for years. 100% cotton chenille wash mitts and pads are also excellent but will need to be replaced from time to time.
