How to Clean Man-Made Franke Granite Kitchen Sinks

Stone sinks, such as marble and granite, are a popular choice for kitchens of all decor and design. Franke granite sinks are non-porous, stain-resistant and have an added acrylic resin to the granite to increase its overall durability. If not cared for properly, your Franke granite sink can become dull and scratched. Regular cleaning will keep your man-made Franke granite sink free from stains and mineral build-up.

Fill a container with warm water and add ΒΌ cup of liquid dish soap. Mix together with a wooden spoon.

Saturate a nylon scrub brush in the mixture and scrub the granite sink thoroughly.

Rinse the granite sink with cool water to remove the soap residue thoroughly and dry with a soft towel.

Repeat this process daily to keep your man-made Franke granite kitchen sink looking its best.

Mix 1 part cool water with 1 part bleach in a small container. Saturate a white cloth in the mixture and scrub the stain until it is removed. Rinse with cool water and wipe dry.

Combine 3 parts cool water with 1 part white vinegar in a clean spray bottle. Thoroughly coat the inside of the Franke granite sink with the mixture. Gently scrub the sink with a sponge to remove lime scale deposits. Rinse with cool water and dry with a towel.

Saturate a cloth with white vinegar. Lay the cloth directly on top of tough-to-remove mineral scale and spots. Leave the cloth on the area for 15 to 20 minutes. Wipe the kitchen sink with the vinegar-soaked cloth and rinse with cool water.


Do not use abrasive cleaners or cleaning tools on granite. These items could scratch the granite sink.
