Can a cap be washed in a washing machine?
For many people, washing a cap in a washing machine is a last resort. It can be done, but only very carefully and by using a special washing machine programme.

- Take a sponge, dip it in the water, drain off excessive water and start scrubbing gently. Remember to do this gently to avoid damaging the seams on the cap and getting stained. If you want to wash the cap with extreme precision, you can use a brush to reach all the corners, even the dirtiest ones.
- At the very end, rinse the cap gently to remove any detergent, squeeze out any excess water and you’re done! Hand-washing is time-consuming but it’s really effective.
