Before using any stain removers in particular try it on a hidden part of the product. This rule is applied to all products from linen. After dripping of stain remover, let it soak in and hold 2 to 5 min. Then rinse well. If there are no colour changes, you can use selected stain remover. Never pour remover directly into your washing machine and never mix two different stain removers.
