Mineral deposits can lead to discolouration, which you can remove with proper care and attention. 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.
If you do notice that there are darker stains, or if you have a light-coloured sink that is showing more surface staining, you can clean these with a mixture of 50% bleach and 50% water. Dip a nylon bristled brush into the bleach solution, and use it to scrub the stains. Rinse well with water when you're done.
Combine two parts of water with one part of vinegar in a spray bottle. Lightly mist the basin. You don't want to wash away the baking soda (you just want to get it damp.) Use the cloth or brush to loosen the grime, soap scum, and stains.
You can also use a 50:50 solution of bleach and water to remove any stains. You should always make sure to dry granite composite sinks thoroughly after using them. To prevent any permanent staining, don't leave standing water or dishes in your sink.
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.
Yes, composite sinks can withstand boiling water. There is no issue with pouring hot water down a granite, quartz, or solid surface sink.
If you are concerned about water marks being left on the surface, which are more likely to appear on composite sinks of a darker colour, then wiping your sink with a lint-free cloth to dry it off should do the trick. Drying your sink after each rinse will help prevent the build-up of water stains and limescale.
You should always avoid highly harsh chemicals or abrasives such as ammonia and steel wool. Keep in mind that granite composite sinks can be damaged by extreme heat and aluminum cookware. Aluminum cookware can scratch the surface of the stone.
Stubborn Stains – A solution of 50% bleach, 50% water should only be used for tough, stubborn stains. Let the solution sit in the bottom of the sink for one hour; then scrub. Rinse well. Also, the use of Bar Keepers Friend (directions included on bottle) will help remove stubborn stains.
Stubborn stains
Use a mild abrasive cleaner such as Bar Keeper's Friend and a soft scouring pad. A diluted bleach solution may also be used. Mix 1 part household bleach with 1 part water and let soak in the sink for 1 hour. scrub area thoroughly with a Mr.
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.
A little squirt of washing up liquid (called dish soap, by some) into a cloth will work wonders with soap stains. Just make sure that the washing up liquid you use doesn't contain bleach or any enzymes that might chomp their way into your sink's surfaces.
If you notice stains on your white composite sink, simply make up a mixture of dish soap and water, and wipe the sink down with a lint-free cloth or non-abrasive sponge. For the really difficult stains that just won't budge, try a mixture of vinegar and water and scrub the area with a soft bristle brush.
Do not use a pressure washer with greater than 3100 psi pressure and do not hold it any closer than 25cm above the composite decking boards as doing so, you will be more likely to damage your boards. The sheer force of the water pressure can cause the surface of the decking boards to splinter, causing long-term damage.
If your deck is made from concrete, pavers travertine, brick, stamped concrete or composite decking, you can clean and refresh it for summer using OxiClean™ Versatile Stain Remover.
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.
It is best not to use undiluted vinegar, but you can make a solution with 50% water and 50% vinegar to use on your composite sink. Spray the solution onto your sink, focusing on the limescale stains. Scrub away with a nylon brush until it is removed. Finally, rinse the sink with some clean water.
If you have a modern white porcelain sink, then bleach can be used sparingly to lift tough stains, but it should not be used as an everyday cleaner, or on large areas of porcelain. You should also avoid using bleach on vintage or colored porcelain, as this could cause permanent damage.
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.
SURFACE LUSTER
Clean, rinse and dry sink completely. To restore luster and extend the time between cleanings apply a thin, even coating of Quartz Sink Conditioner, food-safe mineral oil, or olive oil to the entire sink surface with a cloth. Remove excess with a cloth or leave overnight. Reapply as needed.
