Faults, stains and damage: diagnosis before treatment

Identify what has actually gone wrong with a commercial floor or fabric before anyone puts a machine on it.

Most failed cleans are failed diagnoses. Greying that looks like dirt is often abraded fibre; a stain that keeps coming back is usually wicking from the backing rather than a stain at all.

Each page here explains the mechanism, why the usual in-house attempt makes it worse, what correction is realistic, and where a floor has genuinely passed the point of being cleaned back.
