Our formula does not contain harsh oxidizing agents such as peroxide or chlorine bleach and is generally safe on all washable fabrics EXCEPT rayon and acetate (which hate getting wet anyway).
To be safe, you should check any labels and if you read, "wash separately," "wash in cold water," "hand wash," "do not use detergent" or "turn inside out to launder", it may indicate the dyes in these items are not colorfast. If you are under any doubt we recommend you do a colorfast test before using any of our products.
