DO YOU STRUGGLE WITH SWEAT STAINS ON PRIMARY HATS?
Washing instructions from Supplier:
If your child perspires heavily you will notice a white substance form on the bottom of the crown and where the brim meets the crown. This substance is a build up of salt from the perspiration.
In this event you can rinse the hat out in cold water ONLY on a weekly/fortnightly basis to remove the salt build up from the fabric.
If left unattended, this salt stain will fade the fabric.
Do not soak in Nappy San or other soaks or scrub with detergents as this will fade / mark the fabric.
