Cleaning & Maintenance – Composite Granite Sinks
A kitchen sink is a heavy duty utensil and over time may show traces of wear; regular cleaning to remove dirt is the best form of maintenance and extends its life and appearance.
To keep your sink looking its best, clean with washing-up liquid after use and wipe dry. Avoid leaving stainable waste such as tea bags in the bowl. Deep clean weekly in soft-water areas (twice or three times weekly in hard-water areas) using recommended products.
Blanco Activ, Franke Colour Sink Cleaner, Franke Magic Sponge, Cramer Mineral-Star and Schock Easy Care suit composite granite sinks. Regular use helps limit limescale and keeps the surface looking good.
