To use the ASSOS Men's Chamois Creme, simply apply a thin layer to the areas that come into contact with the saddle before your ride. This will help reduce friction and keep you comfortable. Remember, a little goes a long way, so don't over - apply. As for maintenance, keep the cream in a cool, dry place. Avoid exposing it to extreme temperatures. After each use, make sure to close the container tightly to prevent it from drying out. Also, when washing your chamois, the cream should wash out easily without leaving any stains. If you have any skin sensitivities, it's a good idea to do a patch test first.
