"Acid and alkaline-sensitive" means that products such as vinegar, window/glass cleaner, CLR, lemon juice, oven-cleaner, and bleach should never be used on granite. Using any of the mentioned products leads to a chemical damage called "etching."
Removing Hard Water Stains and Mineral Deposits:
These can be tough to remove. Best way to remove these stains is using a hard water stain remover such as Lime-Away or CLR. You can do this once every 1 or 2 months.
While composite sinks are quite resistant to stains and scratches, it's important to note that they can be damaged by harsh chemicals and abrasive scrubbing devices.
For a daily clean, use some soapy water and a sponge or soft cloth and be sure to dry off the sink when you're finished. This will allow you to remove any stains, limescale and water spots before they have a chance to take hold.
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.
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.
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.
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.
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.
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.
Composites are non-porous – This makes them much more sanitary than granite, which can conceal bits of food and bacteria in its crevices. Composites also can withstand disinfectant products without damaging the material, unlike granite.
Clean water and rust stains from sinks and drains effortlessly with CLR Calcium, Limescale & Rust Remover. Before you get started, always use gloves and check if CLR is suitable to be applied on the material you are trying to clean. Test the CLR on an inconspicuous spot first before applying to entire surface.
We recommend not leaving CLR on a surface for longer than two minutes. Always ensure that the CLR is rinsed off thoroughly after use.
Unlike natural granite, a composite granite surface won't require sealing.
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.
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.
Yes, composite sinks can withstand boiling water. There is no issue with pouring hot water down a granite, quartz, or solid surface sink.
It is essential you avoid extreme variations in temperatures coming into contact with your sink – such as pouring out a pan of boiling water followed by ice cold water. This can cause thermal shock in composite sinks and will result in hairline cracks appearing.
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.
Once your granite composite sink is cleaned, you can restore its shine using mineral oil. Apply a tablespoon of mineral oil to a soft cloth and buff using a circular motion. Wait 1 minute, wipe away and enjoy the luster.
Quartz tends to be more affordable, and it comes in a vast array of color choices because it's basically a manmade product. Granite composite, on the other hand, although a little pricier, is indestructible as a countertop or sink because a large percent of the product is actual stone from the earth's crust.
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.
