Features

Mop has the interconnected pore structure of P.V.A which, unlike fibrous fabrics, will not produce lint.
Highly water affinitive, they quickly absorb water while remain resistant to solvent.

Care instruction
Soak in water and wring well before use.
Make sure the cloth is clean
Refer to the following table when using with solvents
