Back on Track products should be kept clean for maximum effect and can be washed multiple times without damage. Always follow the washing instructions on the label attached to the garment. The minerals that create the "Back on Track" effect are woven into the products. However, there are a few points to consider.
Garments should not be tumble dried.
Do not wash with bleach or rinse aid.
Wash colors separately and turn garments inside out before washing.
For knitted garments, it is recommended to dry the product flat on a towel.
Waterproof products should be washed with a suitable detergent.
Iontex garments or other sportswear containing cotton or viscose may shrink when washed for the first time. If this happens, gently stretch the garment while it is still damp.
Do not store products in direct sunlight unless necessary.

In many cases, minerals neutralize unpleasant odors, meaning washing them with a regular mild detergent is sufficient.
Sportswear detergents generally contain substances that can damage textiles; please check this before use. Products should not contain: Aluminum chloride, enzymes, silver, or citrine. These substances can alter the structure of minerals and, therefore, their properties.
