How to Remove Oxidation from RV Fiberglass

As an RV owner, it’s crucial to maintain its condition, including knowing how to remove oxidation from RV fiberglass.

This not only looks unappealing but can also decrease your RV’s value.

There are several methods of how to get the oxidation off of your RV’s exterior, ranging from hand buffing to using power tools or wet sanding. With some effort and the right tools, you can restore your RV’s exterior and prevent further damage.

In this article, we’ll cover some effective ways to remove oxidation from RV fiberglass. We provide step-by-step instructions and tips for both experienced and new RV owners. With our guidance, you can keep your RV in top shape and travel with confidence.

Apply the Cleaning Solution

Now that you have prepared the surface of your RV fiberglass, it’s time to apply the cleaning solution. There are different types of solutions that you can use, such as vinegar, fiberglass restorer, or high-grade super duty polishing compound. Choose the one that works best for you and follow the manufacturer’s instructions.

If you are using vinegar, mix equal parts of vinegar and water in a spray bottle. Spray the solution on the surface of the fiberglass and let it sit for a few minutes. Then, scrub the surface with a soft-bristled brush or a sponge. Rinse the surface with water and dry it with a clean towel.

If you are using a fiberglass restorer, apply a small amount of the product to a non-scratch kitchen sponge. Buff the RV by hand, applying gentle pressure. Wipe off the product with a clean rag. Repeat the process until you have covered the entire surface of the fiberglass.

When using a high-grade super duty polishing compound, apply it with an electric buffer or soft cloth. Work in small sections and apply gentle pressure. Remove excess product with a clean rag and repeat until the entire fiberglass surface is covered. For extra shine, place a microfiber cloth over the power buffer and go over the area one last time. The results will impress you!

Remember to wear gloves and protective eyewear when working with cleaning solutions. Also, make sure to work in a well-ventilated area to avoid inhaling fumes.

Rinse the RV

After sanding your RV fiberglass with a wet sandpaper and applying an oxidation remover, it’s time to rinse the RV. Rinsing the RV is a crucial step in the process of removing oxidation from the fiberglass. Here are some tips on how to properly rinse your RV:

  • Use a garden hose or pressure washer to rinse the RV. Be sure to use a low-pressure setting to avoid damaging the fiberglass.
  • Rinse the RV from top to bottom to ensure that all the oxidation remover and debris are washed away.
  • Pay attention to the corners and crevices of the RV, as oxidation and debris can accumulate in these areas.
  • Use a microfiber towel or chamois to dry the RV after rinsing it. This will prevent water spots from forming on the fiberglass.

It’s important to note that you should never let the oxidation remover dry on the RV fiberglass. This can cause damage to the fiberglass and make it more difficult to remove the oxidation. Always rinse the RV thoroughly and dry it immediately after applying the oxidation remover.

By following these simple steps, you can effectively remove oxidation from your RV fiberglass and restore its shine. Remember to take your time and be patient, as removing oxidation can be a time-consuming process. With a little effort, you can have your RV looking like new again.

Dry the RV

After you have rinsed the RV thoroughly, it’s time to dry it. Leaving water droplets on the surface can cause water spots, which can be difficult to remove. Here are a few tips to dry your RV:

  1. Use a microfiber towel or chamois to dry the RV. These materials are gentle on the surface and absorb water well.
  2. Start at the top of the cleaned area and work your way down to the bottom. This will prevent water from running down onto the areas you have already dried.
  3. Dry the windows and mirrors with a separate towel to prevent streaks.
  4. Open all the doors and compartments to allow air to circulate and dry any hidden areas.

It’s important to make sure that the RV is completely dry before moving on to the next step. If you’re in a hurry, you can use a leaf blower or a compressed air gun to blow the water off the surface. However, be careful not to scratch the surface with the air stream.

Once the RV is dry, you can move on to the next step, which is waxing and polishing. This step will protect the surface from future oxidation and keep it looking shiny and new.

Apply Wax

After you have removed the oxidation from your RV’s fiberglass, it’s important to protect the surface from future damage. Applying a coat of wax can help prevent oxidation and other forms of damage caused by exposure to the elements.

Here are a few steps to follow when applying wax to your RV’s fiberglass:

  1. Clean the surface with soap and water to remove any dirt or debris.
  2. Dry the surface completely with a clean towel.
  3. Apply a small amount of wax to a clean, dry cloth.
  4. Using circular motions, apply the wax to the surface of the fiberglass.
  5. Allow the wax to dry completely.
  6. Buff the surface with a clean, dry cloth to remove any excess wax.

It’s important to choose a wax that is specifically designed for use on fiberglass surfaces. Look for a product that provides UV protection and is easy to apply and remove.

By regularly applying wax to your RV’s fiberglass, you can help protect the surface from damage and keep it looking great for years to come.

How To Prevent RV Oxidation

Now that you’ve removed the RV fiberglass oxidation, here are a few tips on how to keep it from happening again:

  • Wash your RV regularly. This will help remove dirt, grime, and other pollutants that can cause oxidation. Use a mild soap like Dawn, and avoid using abrasive cleaners or harsh chemicals.
  • Wax and polish your RV regularly. Wax protects the fiberglass from damage like oxidation. Use a marine or RV-specific wax and apply it according to the instructions on the package.
  • Cover your RV while in storage. Covering your RV will help protect it from harmful UV rays, which are what causes oxidation. If you don’t have a covered or shaded spot to park your RV, you can use tarps or RV covers.

By following these tips, you can help prevent RV fiberglass oxidation and keep your RV looking its best for years to come.
