Can I use Bathroom & Shower Cleaner with a Diamond Sponge?Updated 10 days ago

Yes. Diamond Sponges pair well with Bathroom and Shower Cleaner for the toughest bathroom build-up: hardened soap scum, limescale rings, neglected grout lines and mineral deposits on glazed tiles. The foam softens the grime and the sponge mechanically lifts it off. It is the most aggressive scrubbing tool in the Koh range, so think of it as a last resort rather than an everyday tool. Start with the Ultra Pro Bathroom Mitt for general bathroom cleaning, step up to Scrubby Pads for stuck-on grime, and only bring out a Diamond Sponge for extreme build-up. Never use it on plastics, chrome, stainless steel or coated surfaces.

Work your way up the abrasion scale and start with the gentlest tool that gets the job done. The Ultra Pro Bathroom Mitt handles the large majority of bathroom cleaning: general soap scum, body oils and day-to-day grime. For stuck-on or thicker build-up, step up to Scrubby Pads, which are more abrasive but still safe for most sealed bathroom surfaces. Only bring out a Diamond Sponge when the first two have not shifted it. Going in with the most abrasive option risks damaging a surface you never needed to touch with that level of scrub.

Spot test first in a hidden area. Wet the sponge before you use it, because dry use increases abrasion and surface risk. Spray Bathroom and Shower Cleaner onto the target area and let the foam sit for five to ten minutes to soften the build-up. Then use a gentle circular motion with light pressure, because the sponge does the work rather than your arm. Rinse the surface thoroughly afterwards and check for any dulling or marks. Stop immediately if you see any surface change.

A Diamond Sponge will leave microabrasions on anything shiny, soft or coated. Never use it on plastic, including shower screens, toilet cisterns and tap handles, on chrome or polished metal fittings, on stainless steel, on powder-coated surfaces, on painted or gel-coat finishes, on acrylic or fibreglass baths and shower trays, on mirrors, or on any surface with an aftermarket protective coating such as EnduroShield. Stick to the Ultra Pro Bathroom Mitt for anything on that list.
