How do I test for colour fastness?
More and more garments are manufactured using non-colourfast fabrics. As such, it is essential to pre-test most laundry additives prior to use to avoid colour loss. To avoid costly mistakes you may wish to follow the instructions below:
Test in an inconspicuous area of the item to be treated e.g. The hem, under arm, inside pocket, zip placket. Dampen the area with water and apply a small amount of the stain removal product. Allow the product to soak in for up to 10 minutes. Blot the area with a white cloth. Check for any colour transference onto the cloth. If any colour appears on the white cloth the item is not colourfast to the product and is not suitable to be used. Then, allow the test area to dry out. Check for any colour loss before rinsing thoroughly. For Dr. Beckmann Colour Run Remover, follow the colourfast test instructions exactly as directed on pack.
