How to Care for your Granite Composite Sink
Granite composite sinks are attractive, versatile, durable and long lasting. By following the suggestions below, your granite sink will maintain a new appearance.
Routine Care & Maintenance
The best way to avoid stubborn stain build-ups is to clean your sink with a sponge and soapy water after each use. Rinse and dry with a clean, soft cloth to avoid water spots or soap film buildup.
Removing Stains & Scuff Marks
For a deeper clean, we recommend using a mixture of baking soda and white vinegar using a soft cloth or soft-bristle brush to clean the sink and problem areas. Non-abrasive cleaners such as Bar Keeper’s Friend or Soft Scrub along with a soft scouring pad should remove most stubborn stains with multiple cleanings. (Do not use for daily cleaning.) Use caution not to leave any cleaning product on for long periods of time. Always rinse thoroughly and dry with a clean, soft cloth. Applying a thin layer of mineral oil to the sink using a paper towel will help keep the the sink looking new.
Mineral Deposits
Hard water and minerals in the water can leave white stains on your sink. The best way to remove these stains is with a hard water stain remover such as Lime-Away or CLR. You can do this once every 1 or 2 months. Follow the instructions on the bottle. If you want to avoid chemicals, you can use vinegar instead. Spray vinegar on the entire sink and let it soak for 30 minutes. You can place paper towels on the sink to allow the vinegar to stay soaked on the sink surface. After 30 minutes use a brush to scrub and then rinse with water. Apply mineral oil (or baby oil or olive oil) to the entire sink surface. This will prevent hard water and mineral deposits from building up on the sink surface.
It is important to note the following about your granite composite sink:
- Do not use full strength bleach or cleaners with ammonia.
- Do not use chemical drain openers.
- Do not use harsh chemicals.
- Do not use steel wool and abrasive sponges.
- Do not use the sink to clean paint or grout materials.
- Granite composite sinks can be damaged by extreme heat.
- Aluminum cookware can scratch the surface of the stone.
Degreasing
Take a sponge or soft cloth and mild dish soap. Scrub gently in circles. Flush the sink with warm water.
Descaling
Use a regular descaler without formic acid. Follow manufacturer instructions. Rinse the sink with water.
Removing Scratches
Over time, scratches from silverware, pots, and pans may occur in the sink. Using a Scotch-Brite eraser pad and water, gently scrub the surface until the scratches disappear. Do not use scouring pads or scouring powders.
Brightening
Fill 2 cm of water in the sink. Use chlorine or oxygen-based bleach. Let the bleach set for 25 minutes, then rinse the sink thoroughly with water.
