Certain fabrics don't behave well when submerged in water and will likely end up with damage. Be especially on guard with items made from velvet, suede,
Velvet is an incredibly popular choice for apparel and home décor, but the fuzziness and composition mean it's not the best suited for cleaning with water.
Suede is one of the most classic and refined fabric choices available, but never saturate suede with water, as the fabric will become brittle and lose its texture.
Instead, regularly brush or vacuum away debris, use a damp muslin cloth to spot-clean, and look for a specialized velour cleaner for more set-in stains.
