Got this from my 1986 manual for canvas.
IMPORTANT:
The canvas should never be stored wet for extended periods of time because it may mildew and lose its strength. If the canvas must be stored wet, set it out to dry as soon as possible.
Should mildew develop on your canvas or vinyl enclosure due to the necessity of closing the unit wet, the mildew can be removed in the following manner:
Mildew Solvent:
A simple but effective solvent to remove mildew from tents or other canvasโlike fabrics can be made using ordinary household items. In about eight ounces of water, dissolve two teaspoons of salt and two teaspoons of concentrated lemon juice. Wash the mildewed cloth with this solution, then rinse with fresh water. Let dry in open air before using.
The vinyl over the bed areas can be cleaned in the same manner as the canvas. When necessary, automobile convertible top cleaners can be used to remove stains.
IMPORTANT:
Follow the manufacturerโs instructions carefully for use of such cleaners or damage to the vinyl surface could occur.
The use of insect repellents, hairsprays, and deodorants inside the camper when sprayed on the canvas surfaces will cause a breakdown of the water repellency of the fabric. We suggest, therefore, the very limited use of such sprays inside the unit during camping as damage to the canvas enclosure could result.
The zippers on your canvas can be lubricated by using a paraffin wax. The use of paraffin on the zippers will enhance their ease of operation around the canvas sections and windows.
