Exterior Maintenance

How To Maintain Our Trailers

Caring for the exterior

Taking care of the exterior of your Lang Trailer is very much like caring for a RV or  Boat.  The more care given the better it will look and the longer it will last. 

Washing, Waxing, Polishing

Although we do not endorse any specific brand of cleaning products, we recommend using products specifically formulated for Gel Coated Fiberglass normally found in the RV/Marine section of most auto part stores, Camping World, West Marine, Amazon, Etc.
Try to select a brand of product that you are familiar with, or feel comfortable with and follow the How to Use section located on the label. 

Start by spraying off the entire trailer including the roof and undercarriage with plenty of water to remove all the grit and grime from all surfaces of your trailer before hand washing.
  • This will help remove grit and road debris which may become lodged in your sponge, rag, or brush which could scratch the surface when hand washing.
The use of abrasives or industrial cleaners such as Xylene type products can damage and or remove the gel coat layer and therefore should never be used on any fiberglass surface


Lang Specialty Trailers goal is to create innovative restroom trailers that are not only eye appealing, but are durable, easy to install, easy to clean, and functional for the professional restroom trailer operator.
