It is important to note the following when cleaning 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.
First, we want to make sure we do not accidentally damage the surface. Avoid using any harsh/acidic/alkaline-containing products on your sink. This means avoiding lemon juice, vinegar, bleach, window cleaner, oven cleaner, and most leading brands formulated to remove Calcium, Lime or Rust, ammonia, et cetera.
Use soft or micro fibre cloths (eg. E-cloth). A 50% mix of water and white vinegar can be used to remove limescale deposits, ensure to rinse thoroughly after use, do not leave the vinegar in contact with the surface. A nylon scratch pad or toothbrush can be used on difficult areas.
Hard Water Mineral Deposits (Calcium, Magnesium, Lime)
Unless you wipe your sink dry after every use, water left behind will eventually evaporate. When water evaporates, minerals such as calcium, magnesium, and lime are left behind, bonding to the surface. These spots are called mineral deposits.
Instead, it is suggested that a simple solution of 50% white vinegar and 50% water is your best bet. Make up the solution into a spray bottle, spray the afflicted area, and with a sponge or brush give it a gentle scrub. Follow this up by rinsing away the vinegar with water and drying off the sink with a towel or cloth.
Get some white vinegar, put it in a spray bottle with water (50:50 should do it) and give that sink a good spraying, all over. Then wipe down with a microfibre cloth. You should find that vinegar will keep your sink looking sensational.
Yes, composite sinks can withstand boiling water. There is no issue with pouring hot water down a granite, quartz, or solid surface sink.
Removing Stains and minor scuff marks
Rinse well. Also, the use of Bar Keepers Friend (directions included on bottle) will help remove stubborn stains. Finally, clean with BLANCOCLEAN to put a protective coating back on the sink's surface.
— These sinks are built to withstand the test of time. Not only are they extremely durable, but if you take care of them properly, they can handle the most vigorous scrubs and dishes. They won't tarnish or rust, so you can rest assured that your black sink will remain spotless.
If your composite sink has limescale staining or hard water stains, these can show up clearly against a dark-coloured sink. For these, you do need to use a diluted vinegar to help remove them. The key is not to use straight vinegar on the sink, but to make a mixture that is 50% water and 50% vinegar.
Black stainless steel is more resistant to smudges, fingerprints, and water spots. Black granite composite sinks are more likely to show hard water spots and limescale deposits. It's important to clean your black kitchen sink weekly to keep it tidy and prevent the need for deep cleaning.
This type of sink is easy to clean
Using a non-abrasive cleaner will keep it clean. Taking care of it properly will preserve its color for many years. Keeping it clean is also important. You can use a magic eraser sponge to remove stains and a 50/50 water-bleach solution for cleaning.
Bleach will cause your composite deck to fade and chip. It is incredibly corrosive and will eventually discolour and damage your deck boards. Bleach and industrial cleaners contain harsh chemicals and should be avoided. Instead, use a cleaning product that is made specifically for composite decking.
CLEANING of GRANITE COMPOSITE SINKS
Generic stains should be removed immediately. Cleaning powders and creams which are even slightly abrasive should not be used, nor chemically aggressive detergents.
Step 1: Run some warm water through your composite sink. Step 2: Wipe your sink with soapy water. Step 3: Apply baking soda paste to the stains. Step 4: Use a vinegar/water solution to deal with limescale or water stains.
Do Not Use On Granite or Marble. If you have soft surface countertops like granite or marble, step away from the magic eraser. You can use them on laminate, Corian, quartz, and other solid surface countertops, but do a spot check.
Clean the heck out of the sink, then clean it again with rubbing alcohol. Soak/dip the cups in hot water to make them more pliable, then apply a little petrol jelly around the cup.
For a more thorough clean, sprinkle baking soda over the whole sink, then spray with a 75/25 solution of white vinegar and water to create a fizzing solution. A gentle scrub with a soft sponge and an old toothbrush is enough to give your sink a thorough clean.
If you know your suburb is prone to hard water, a black sink may not be the right choice for you. Hard water can leave a white marks on the sink. You can not use harsh chemicals in the sinks either as these can leave marks too.
Quality composite granite sinks are formed under high pressure, making them nonporous, hygienic, and resistant to heat, stains, scratches, and chips. However, cleaning and removing stains from a granite composite sink can be tricky.
Use a moist sponge to make the inside of the sink slightly damp. Sprinkle baking soda over the stain until it is completely covered. Use a sponge or cloth to gently scrub in small circular motions until the stains are gone.
