To ensure your rash grad stays in good condition, you need to clean it out properly. Rinse out your rash guard as soon as you come from the water, as that will ensure that any particles that might have been embedded in the fibers are removed. If you plan on washing it, then ensure you avoid hot water because it will make the fibers warp used to the cold or lukewarm water. Since it is so fragile, ensure you hand wash it and use biodegradable soap. That way, you do not have to worry about contaminating the water you plan on surfing or swimming in. You can get the biodegradable soap from any green stores that are working. It ensures a better ecosystem. Once you hand wash it, let it hang to dry away from direct heat or sunlight. Do not roll it up when folding or store it in your car where it might get too hot.
