How do I clean the rubber trim on my RV?

It is easy to clean the rubber trim on your RV, as you’ll need just a few drops of bleach, dish soap and plenty of water.

RVs spend so much time on the road traveling that they often become layered with dirt and grime caused by road grime, exhaust fumes and flying debris. You will need to regularly detail your RV in order to get the vinyl or rubber exterior trim looking new, clean, and fresh.

  1. Combine an equal part solution of liquid bleach, dish soap and water in a spray bottle and spray on the areas of extreme soiling on your rubber trim. Use a soft RV brush to clean the area thoroughly. Rinse off with water.
  1.  Add 1/3 cup dishwashing liquid for every gallon of water you use in a bucket. Use a large and soft sponge soaked with the mix to evenly clean the exterior of the RV, making sure that the soapy water does not dry out before you have time to rinse it off. 
  1. Scrub the remaining hard areas with the brush to remove excess dirt.
  1. Use the spray nozzle on a hose or pressure washer to thoroughly rinse the siding. If you are using a pressure washer, stand a distance of 4 feet and do not use temperatures above 120 degrees.
  1. Finally, spray the RV trim with a protector such as 303 Aerospace Protectant, following the manufacturer’s instructions.

Note: Avoid using harsh abrasive brushes or cleansers which will scratch the vinyl or rubber trim. And a 30% vinegar and water solution can also be used to clean rough rust stains.

How do you remove mould from your RV trim?

To permanently eliminate mould from your RV trim, you will need the following products and tools:

The best way to eliminate mould and prevent it from forming again is by fixing the root problem. For this, it will be necessary to combine several products that eradicate it, along with others that prevent it from reproducing again. The steps are as follows:

  1.  Remove the mould: First, to remove existing mold, the plaster moulding will be sprayed with the mould remover cleaner and allowed to act for about 10 to 15 minutes. After that time, it will be rinsed with a damp sponge.

In the event that mould has also settled in the tile joints, a joint cleaner should be applied with a sponge or scouring pad. After leaving it to act for 2 or 3 minutes, it will be rinsed off with water.

  1. Prevent the appearance of mould:  Once the area affected by mold has been cleaned, a product that destroys the fungi and spores will be applied so that they do not reproduce again. For this, use the Fungistop gel. Its application is very comfortable since the tube contains a sponge that makes it easier for the product to penetrate the affected area.

Unlike the two products used above, Fungistop should not be rinsed with water. You just have to wait until it dries.

In any case, it is advisable to renew the joints over the years for better maintenance and preservation of them.

On the other hand, to avoid condensation and prevent the formation of mold and humidity due to this problem, put on the plaster or plaster with Aguaplast Anti-Condensation. Its application is similar to that of other plates:

  • Mix a part of powder with half of the water until obtaining a homogeneous paste. For example, for 500 g of powder, you will need 250 ml of water.
  • Apply with a spatula or trowel depending on the size of the surface to be covered.
  • Wait between 12 and 24 hours for it to dry. The time will depend on the thickness of the layer and the environmental conditions.
  • When it has dried, the entire surface will be sanded to smooth it and prepare it for painting.
  1.  Paint the rubber trim: The last step will be to paint the surface with special paint for walls where condensation moisture is generated. In this sense, Lisomat Anti-condensation has the following advantages:
  • It is a matte acrylic paint with anti-condensation, thermal insulation and noise-damping properties.
  • Resists water and humidity, protecting against the appearance of bacteria, mould and fungi. It is also breathable to water vapour.
  • It is water-based and can be used both indoors and outdoors.
  • For its application, you can use a brush or roller and dilute it with 5% water to achieve greater penetration. The drying time to the touch is one hour and the repainting time is 24 hours.
