The Right Way to Rinse and Dry a Large RV or Motorhome

Rinsing and drying a full-size RV can feel overwhelming — miles of panels, windows, and chrome trim that seem impossible to finish before the sun leaves water spots behind. But with the right technique and tools, you can dry your rig quickly, safely, and streak-free every time. Here’s how to rinse and dry your RV like a pro without scratching or wasting hours.

Why Rinsing and Drying Properly Matters

Rinsing and drying may sound simple, but they’re two of the most common steps where RV owners damage their paint or coatings. Poor rinsing leaves behind soap residue and minerals that can etch into the surface. Rushing the drying process can cause swirl marks or water spots that are hard to remove later.

The key is using the right water pressure, drying technique, and microfiber tools that are large enough to handle your RV’s massive surface area.

Step-by-Step: How to Rinse and Dry an RV the Right Way

Step 1 – Rinse Thoroughly from Top to Bottom

Always start from the roof and work downward. This ensures that dirt and soap flow off the panels instead of drying in streaks. If you use a pressure washer, choose a wide-angle tip (like 40°) to safely rinse without damaging decals or seals.

Step 2 – Use The Super Soaper for Lubrication

Before final rinsing, apply a layer of The Super Soaper using a foam cannon or pump sprayer. This step adds lubrication and helps remove any remaining grime. Let it dwell for a minute before rinsing it off again with steady water flow.

Step 3 – Perform a “Sheet Rinse”

After your final foam rinse, remove the nozzle from your hose and allow the water to flow freely over the panels. This technique “sheets” the water off, minimizing beads and cutting drying time by 50% or more.

Step 4 – Dry Using the Massive Drying Towel

Once the water has sheeting off, fold your Massive Drying Towel into quarters and gently lay it flat on the surface. Drag it across the panel using the towel’s weight rather than pressure. The dual-pile microfiber will absorb gallons of water quickly without streaking.

Step 5 – Blow Dry Remaining Water

If you have access to a leaf blower or dedicated car dryer, use it to blow water out of mirrors, seals, and vents. This prevents hidden drips later.

Step 6 – Apply Tough As Shell Ceramic Spray

Once fully dry, mist Tough As Shell onto a microfiber towel and wipe it over the surface for long-lasting shine and protection. This also helps future washes rinse cleaner and dry faster.

How to Avoid Water Spots When Drying an RV

Water spots happen when minerals are left behind as water evaporates. To avoid them:

  • → Wash and rinse in the shade or early morning.
  • → Avoid washing on hot panels or under direct sunlight.
  • → Use filtered or deionized water for the final rinse.
  • → Dry immediately after rinsing — don’t let water air dry.
  • → Use Tough As Shell regularly to reduce water adhesion and spotting.

Method Time Required Water Spot Risk Recommended Tools
Traditional Hose Rinse 45–60 minutes Medium Super Soaper + Massive Drying Towel
Sheet Rinse + Blow Dry 30–40 minutes Low Filtered water + blower + drying towel
Filtered Water Rinse (DI) 25–30 minutes Very Low DI Rinse System + Tough As Shell

Pro Tips for Faster, Safer RV Drying

  • → Fold your drying towel often to use fresh, dry sections.
  • → Dry glass and mirrors first before water dries.
  • → Use a separate towel for lower panels to avoid cross-contamination.
  • → Apply Tough As Shell to wet panels for a drying aid effect.
  • → If working alone, dry in sections to prevent spotting.

Best Practices for Maintaining a Spot-Free Finish

Even if you wash often, following these small habits will keep your RV cleaner longer:

  • → Store your RV under cover or use a high-quality RV cover to reduce dust buildup.
  • → Rinse the front cap after long drives to remove bugs and salt.
  • → Keep a bottle of The Super Soaper ready for touchless rinses between full washes.
  • → Apply Tough As Shell every 4–6 weeks to maintain slickness and gloss.
  • → Always dry with clean, edgeless microfiber towels to prevent scratches.
