Disana ox gall soap

Ox gall soap is an old household remedy for removing stubborn stains from wool and silk clothing. It is used when a regular wool shampoo is not strong enough to remove the stain.

When a stain occurs, apply a drop of soap to the affected area as soon as possible and gently massage it into the fabric. Then wash or rinse the soap out. If you only notice the stain later, you can still use ox gall soap. Sometimes it is necessary to let the soap soak in for a few minutes or to apply it several times to get sufficient results.
