Swimwear – Always rinse after use in cold water and dry immediately. Do not soak, bleach or wring.  Line dry in shade. Do not tumble dry. Cool iron only if needed and never on the print or printed label.
Avoid rough surfaces.
If sand becomes trapped in your swimsuit, carefully stretch dry fabric over thumbnail and sand will pop out.
Some sunscreens and water will mark our fabrics, if this happens use a stain remover like Sard wonder soap.  Gently rub it into the swimsuit and rinse out.
