Staining of fabric can sometimes occur with sunscreens. The body oils and acids reacting with the sunscreen, causing discolouration where the product rubs into the fibre. These stains can be removed if a pre wash stain remover is used. Soaking the garment overnight in a product such as Napisan may be required for stubborn stains.
SunSense Sensitive/Sensitive Matte Staining:
As SunSense Sensitive and SunSense Sensitive Matte are not water soluble, any stains caused by the product will not be removed by soaking the clothing in a stain removing solution. For this reason, the product label carries the warning- “Contact with clothing may cause discolouration”.
Experiments in our laboratory have shown that staining caused by pigments can be removed successfully from clothing by using a stain remover such as Sard Wonder Soap or Sard Powder mixed with water to form a paste. Rub either of the above products onto the stain and try to push the pigment particles out of the fabric by using a circular motion and then wash the garment as per label instructions.
Above statement is also applicable to other tinted SunSense sunscreens.
