FAQs
Q: How often should I wash and wax my RV?
A: It depends on how often you use your RV and the conditions it’s exposed to. As a general rule, washing your RV every 2-3 months and waxing it twice a year is a good starting point.
Q: Can I use regular car wash soap on my RV?
A: While you can use car wash soap, RV-specific wash products are formulated to be safe for fiberglass and often contain additives that provide extra cleaning power and UV protection.
Q: What’s the best way to apply RV wash and wax?
A: Follow the manufacturer’s instructions on the product label. Generally, you’ll want to wash your RV from top to bottom, using a soft sponge or brush. Rinse thoroughly and dry with a microfiber towel. Apply wax in thin, even coats and buff to a shine.
Q: Can I use a pressure washer to wash my RV?
A: Yes, but use caution. Keep the pressure low and use a wide fan nozzle to avoid damaging the fiberglass. Avoid spraying directly at seams or seals.
Q: Are waterless wash and wax products as effective as traditional wash and wax products?
A: Waterless wash and wax products are great for light cleaning and maintenance, but they may not be as effective for heavily soiled surfaces. For the best results, use a traditional wash and wax product for deep cleaning and a waterless product for quick touch-ups.
