Unlike natural granite, a composite granite surface won't require sealing.
Applying a light layer of food grade mineral oil will add a protective repellent layer to your sink - simply leave the oil on the surface for 45 minutes then buff with a cloth. Repeat the process if needed. With a granite composite sink, prevention of stain and limescale build up is key.
Yes, composite sinks can withstand boiling water. There is no issue with pouring hot water down a granite, quartz, or solid surface sink.
Heat-Resistance—while composite sinks are heat-resistant, they aren't heat-proof. It's important to note the acrylic resin binders found in composite sinks can warp or melt when exposed to extreme heat. An example of this is when a hot pot or pan is placed directly in the sink.
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.
Stain Resistant: Unlike natural granite, this non-porous material requires no sealing and will keep from staining by design.
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.
Use Soft Scrub with Bleach Cleanser or Soft Scrub with Bleach Cleaner Gel to free your sink of soap scum, dirt, and stains. Marble and Granite: Tough on stains, yet gentle on your most delicate surfaces, Soft Scrub's Multi-Surface Gel is a rinse-free gel that cleans and polishes marble and granite sinks.
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.
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.
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.
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.
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.
In fact, composite granite is harder and heavier than its natural counterpart, though exponentially less expensive. And, it will maintain its look and strength well, thanks to its non-porous, stain-resistant nature.
Well for those of you who don't like either and are interested in something new, granite-composite sinks have some great benefits but some downfalls as well. Granite composite is the most scratch resistant sink material on the market today.
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.
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.
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.
Some black sinks may show smudges or scratches, but this depends on the sink's material. 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.
Durability. Composite granite sinks are primarily made up of a mixture of quartz granite particles and resin, both of which are incredibly hard-wearing and durable. The result of this is that any knocks that would usually dent, chip or scratch a regular sink will not show up on a composite sink.
The most stain-resistant sink is a stainless steel sink. A stainless steel sink is the most durable and low-maintenance kitchen sink as they are resistant to heat, stains, and scratches.
We recommend using a mixture of baking soda and white vinegar to deep clean your granite sink. 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.
However, it is important to note that granite sinks can be susceptible to staining if they are not properly sealed. On the other hand, stainless steel sinks are also extremely durable and resistant to scratches, chips, and heat. They are also easy to clean and maintain, making them a popular choice for busy kitchens.
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.
