Scratches and chips on the surface of the sink can be removed using sandpaper and then a coat of polish.
For deep scratches on the sink
The recommended cream-based non-abrasive cleaners are effective solutions to polish, restore, and fix scratch in composite sink. It also eliminates deep scratches caused by sharp kitchenware from other composite countertops. – Always remember to clean and wipe the sink after every use.
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.
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.
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.
Composite Granite Sink Disadvantages
Hardness: While some sink materials are more forgiving, composite granite is hard enough to break glassware when dropped onto the surface. This granite composite sink problem is something to consider if you frequently wash breakable dishes in the sink.
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.
Yes, composite sinks can withstand boiling water. There is no issue with pouring hot water down a granite, quartz, or solid surface 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.
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.
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.
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.
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.
Instructions: Spray NuVibrants onto a dry sink and spread evenly with a soft sponge or brush. Allow to sit for 15 min, then wipe excess puddles off with a soft sponge or paper towel. Allow to sit and gel over for 30-45 min, then repeat.
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.
Stain Resistant: Unlike natural granite, this non-porous material requires no sealing and will keep from staining by design.
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.
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.
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.
We wouldn't recommend going in with any acidic or super strong general cleaners for your composite sink. Instead, it is suggested that a simple solution of 50% white vinegar and 50% water is your best bet.
While some types of countertops and sinks are pretty susceptible to stains, granite composite isn't. Because it is non-porous and tightly packed, there isn't much room for stains to seep in. Not to mention, there is usually a good sealer added to the top and polish that can also keep stains away.
Although composite sinks are considered heat resistant, they are not heatproof. Thus, extremely hot pots and pans can potentially warp or melt the acrylic resin binders and damage the sink.
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.
