I have a lot of questions about how to clean and take care of bags or other products made of sailcloth. Depending on the cloth you will need different products but…
First thing to remember when washing your bag is not to use harsh chemicals or solvents. (Paint thinners, Acetone, . . . ). In most cases soapy water will do the job.
Grease, oil and many organic substances can have a permanent staining effect on the fibers of your bag without much risk of damage so proceed with caution in your attempts to rid the bag of these stains as your efforts may cause more harm than good.
Woven Dacron, Spectra or Vectran (mostly white cloth without a plastic film) are a very forgiving material and with a good scrub will come surprisingly clean. We recommend, commercially available organic or environmentally sound detergents or bleach. Before scrubbing begins, pre-treat heavily soiled areas directly with a concentrated detergent solution and let it stand for few minutes while keeping the product wet. This will greatly help to loosen and break up the pollution and dirt particles that have set into the weave of the fabric. Attentively scrub with a sponge or stiff, bristle brush, rinse and air dry.
For bags / products made of aramids (mostly colored yarns covered with a plastic film) we recommend to clean with a commercially available detergent solution and sponge. The reason is that the stains or dirt won’t stick to the film and are easily removed.
Canvas, in general features a soil- and stain-resistant finish that makes clean-up a breeze. Spot wash by sponging briskly with a soapy solution of natural soap in lukewarm water. Rinse thoroughly with clean water to remove soap and air dry. For stubborn stains or suntan lotion, use a fabric stain remover. Follow directions on container. Rinse thoroughly with clean water, and air dry.
Do not use bleach to clean the liner or the inside of the bags.
Note: Bleach will not affect polyester (Dacron), Spectra, or Vectran fabrics. DO NOT use bleach on nylon, aramids (such as Kevlar or Twaron), or Technora. Bleach will destroy these fabrics.
