When it comes to cleaning your RV, the exterior should be washed regularly with a mild detergent and warm water. The interior should also be wiped down using soft cloths and a mild detergent. You can also use special products designed specifically for RV interiors. To protect your motorhome or caravan from the elements, you should apply protective coating or wax to the exterior. This will help keep your vehicle in good condition and prevent any rust or corrosion from forming. For the interior, you should make sure to use breathable covers for furniture and other materials. You can also use dehumidifiers to help keep moisture levels down in the air and prevent any mildew or mould from forming inside your RV.
