What does fabric protector actually do?
A fabric protector coats the fibres with a thin layer that reduces how quickly liquids soak in during the first minutes. The idea is that the liquid beads on the surface so you can blot it before it sinks into the cloth.
But that layer does not stop contamination completely and it does not last for ever. Friction, washing and cleaning wear it down gradually, so protectors are reapplied from time to time according to the product.
We do not promise that any product makes a sofa resistant to stains by a set percentage. It is a helper, not a full shield.
