How to Wash An RV?

To ensure your RV stays in excellent condition and lasts for years, regular cleaning is essential. However, it's not just about splashing water and scrubbing. Knowing the correct methods will help avoid damage and keep your RV looking as good as new.

Here's a simple, step-by-step guide to help you wash your RV effectively and safely:

1. Gathering Supplies

Before you start washing your RV, make sure to gather all the necessary supplies. You'll need a bucket, RV-safe soap, a soft-bristled brush, and microfiber towels for drying. A hose or pressure washer will help with rinsing, and a ladder on hand will help you reach higher spots, especially on the roof.

 2. Pre-Rinse the RV

Start by giving the RV a good rinse with a hose or pressure washer at a low setting. This will help loosen dirt and grime, making it easier to wash.

3. Mix Your Cleaning Solution

Fill up your bucket with water and the RV-safe soap, following the product’s recommended dilution ratio. Avoid harsh chemicals like bleach, as they can damage the RV’s paint, seals, and roof material.

4. Wash from Top to Bottom

Start by washing the roof, using a soft-bristled brush to scrub away dirt and stains. Be careful not to stand directly on delicate areas. Carefully work your way down the sides, front, and back of the RV, washing in straight lines to avoid swirl marks. You can use a ladder if necessary to reach high spots, but be cautious when scrubbing to avoid damaging windows, decals, or seals.

5.    Rinse Regularly

Rinse off soap and grime regularly to avoid drying soap marks. Use a hose or low-pressure washer to ensure all areas are thoroughly rinsed, including the roof and undercarriage.

6.    Clean the Wheels

Use a separate brush or cloth to scrub the wheels. You can use a specific wheel cleaner or the same RV soap, ensuring all brake dust and grime are removed.

7.    Dry the RV

After thoroughly washing the wheels and body of your vehicle, use microfiber towels to dry it. It will prevent water spots and streaks from forming on the surface. Pay attention to windows, mirrors, and metal surfaces to avoid streaks.

 8.    Look Out for Missed Spots

Once dry, look around the RV and check for any missed spots, streaks, or dirt. You can use a cloth to clean up any small areas that need extra attention.

9.    Final Rinse and Touch-Ups

After cleaning everything, give the RV a final rinse (if using wax) and do any touch-ups on spots that might need extra cleaning.

How to Clean the RV Roof?

Cleaning your RV roof is a crucial part of maintenance, as it helps prevent leaks, mold, and premature wear. To clean it without damage, start by determining the material of your RV roof—typically rubber, fiberglass, or aluminum—so you can choose a suitable cleaner.

1.    Determining the Roof’s Material

If you have an EPDM or TPO rubber roof, make sure to use a rubber roof cleaner. For PVC roofs, you can use household cleaners like dish soap. Fiberglass roofs can be cleaned with a mild detergent or a designated RV fiberglass cleaner, along with a soft-bristled brush or sponge mop.

2.    Cleaning the Surface

Start the process by rinsing the roof to remove loose dirt, then apply the cleaner in sections, allowing it to sit briefly on tough stains. Gently scrub back and forth, paying attention to edges, vents, and seams. Once cleaned, thoroughly rinse the roof to ensure no soap residue remains, which could lead to streaks or damage over time.

3.    Inspecting Damages and Applying Protectant

After the roof dries, inspect it for any cracks or wear, and consider applying a protective sealant or UV protectant to extend its lifespan. EPDM or TPO rubber roofs often benefit from a protective UV coating every two years. This helps prolong the roof's life and protects it from the damaging effects of the sun's rays. Remember to follow the product instructions for the application process.

What Soap Should I Use to Wash An RV?

Choosing the suitable soap is a critical first step in ensuring a thorough and safe RV cleaning. Unlike regular vehicles, RVs often have more sensitive exteriors, including rubber roofs, decals, and sealants. For this reason, avoiding products like Dawn or Bleach is essential, which may seem effective but can dry out rubber materials and deteriorate paint or sealant.

Instead, opt for RV-safe soaps that are gentle on your vehicle while still removing grime and dirt effectively. Let’s have a look at some of the highly rated recommendations:

The Camping World Premium Gel Gloss Wash and Wax is a highly concentrated, biodegradable, and environmentally friendly cleaner designed specifically for RVs. It cleans and shines the vehicle's surface without removing the original finish.

Can I Use Power Wash on my RV?

Using a power washer to clean your RV can be efficient and effective , there's also a risk of damage if used incorrectly.

For instance, applying too much pressure can cause damage to your RV's decals, paint, or even seals. The key is to use a lower PSI setting, typically between 1200 and 1900 PSI, which is enough to clean without harming the surface. Always keep a safe distance—around 2 to 3 feet from the RV surface—to avoid stripping off paint or sealants. Focus on using the pressure washer to target stubborn areas like the undercarriage, wheels, or hard-to-reach spots where dirt and grime accumulate.

If you’re concerned about using a traditional power washer but still want the convenience and efficiency of pressure washing, consider the RV Cordless Pressure Washer from Filluck.

Tips and Mistakes to Avoid While Washing an RV

Washing an RV all by yourself can be a tricky yet intriguing event. With the proper methods and techniques, you can safely complete the cleaning of your RV on your own while avoiding common mistakes that can potentially damage your home on wheels.

Let’s look at some of the most important things to consider while completing your DIY washing project:

Never Use Circular Motions to Scrub

Always avoid scrubbing in circular motions, as this can leave swirl marks on the surface. Instead, wash in straight lines to minimize the risk of scratches.

Never Let Water Sit

Allowing water to pool on the surface can lead to water spots or even damage. Be sure to quickly dry the RV after washing to avoid these issues.

Never Ignore the Roof

Many RV owners forget to clean the roof, but it’s one of the most critical areas to maintain. A dirty roof can lead to leaks and damage from accumulated debris.

Work from Top to Bottom

Always start by cleaning the roof first to prevent dirt and water from dripping onto already cleaned sections. This ensures an efficient cleaning process and prevents streaks.

Use a Soft Brush or Sponge

To avoid scratching the paint or decals, always use a soft-bristled brush or sponge. A high-quality RV wash brush with an extendable handle can help you reach higher spots without too much pressure.

By following these tips and avoiding common mistakes, you’ll keep your RV in pristine condition and avoid potential damage during the washing process.
