How to Remove Salt and Road Grime After Winter Travel
If you’ve driven your RV through snowy or coastal regions, road salt and grime can wreak havoc on your paint, trim, and undercarriage. Salt buildup causes corrosion, dulls your finish, and eats away at metal components if left untreated. The good news — with the right cleaning process and products, you can safely remove salt without damaging your RV’s surfaces.

Why Salt Removal Is So Important
Road salt works by breaking down ice — but it also accelerates corrosion. When salt sticks to your RV’s paint, metal, or undercarriage, it attracts moisture, leading to oxidation and rust. This is especially dangerous for RVs with exposed frames or lower panels. Removing salt promptly extends the life of your RV’s paint and prevents costly repairs later.
What You’ll Need
- → Pure Magic Cleaner (acid-based wheel and metal cleaner)
- → The Super Soaper (high-foaming soap for salt removal)
- → Orange Wash Microfiber Towels
- → Undercarriage sprayer or pressure washer (low PSI)
- → Massive Drying Towel
- → Gloves and eye protection
Step-by-Step: How to Remove Salt from Your RV
Step 1: Rinse the Undercarriage First
Always start from underneath. Use an undercarriage sprayer or pressure washer on low pressure to flush out salt buildup from the frame, axles, and suspension. Work slowly and make sure to rinse all corners and hidden spots — especially if you’ve driven through salted roads.
Step 2: Pre-Soak with The Super Soaper
Mix 4 ounces of The Super Soaper in a foam cannon and coat the entire RV, including the lower panels and wheel wells. Let it dwell for 2–3 minutes to loosen salt crystals and grime. This step helps minimize contact washing and prevents micro-scratches.
Break Down Salt Fast
The Super Soaper safely removes road salt, dirt, and grime from RV paint and trim without stripping wax or coatings.

Spray Pure Magic Cleaner directly onto wheels, chrome, and any metal surfaces affected by salt. Let it sit for 20–30 seconds, then rinse. For lower side panels and bumpers, use diluted Pure Magic (4:1 ratio) to dissolve tough grime safely.

After pre-soaking, hand wash the RV with microfiber towels or mitts. Use The Super Soaper in a wash bucket and work from top to bottom. Focus on the front cap, fenders, and trim where grime builds up most. Rinse thoroughly with low-pressure water.
Step 5: Dry and Protect
Use your Massive Drying Towel to remove water safely. Once dry, apply Tough As Shell Ceramic Spray to paint, metal, and plastic for added protection against moisture and UV rays.
