A common issue amongst camper trailer, tent and caravan owners, is packing up the canvas material before it’s 100% dry, or storing it in a humid location for an extended period of time. Next time the camper trailer, tent or caravan canvas is unfolded, there is minor and sometimes heavy mould growth. Once mould gets into canvas or similar heavy fabrics, it takes a lot of elbow grease to remove, and quite often the mould will not come out without leaving stains… if at all. We have the solution.

Vinegar is something that can be done in between the deep cleans with product. Think of the vinegar as a mid maintenance step that can be done on a more regular basis. This can also be done with borax.
The waterproofing step will be done after cleaning proceedures such as concrobium moud stain eraser or heavy Borax treatment.
