02 Why: the two sides
Wool rug
A wool rug has a pile: cut or looped fibre ends standing up from a backing, which hides how far liquid has spread.
A wool rug cannot be rinsed through, so whatever you put on it partly stays in it.
A wool rug is made of keratin, the same protein as hair, so it reacts to alkalis, oxidisers and protein-digesting enzymes the way hair does.
Melamine sponge (magic eraser)

None of the 38 files for wool rug uses it. Absence from the model does not establish either effectiveness or safety.
How long can melamine sponge stay on a wool rug?
Do not use it as a routine home treatment on this material. For accidental contact, follow the product and item instructions and obtain advice if needed.
