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.
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.
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.
A good quality sink should last 10 to 15 years, whereas a cheap sink may only last for a couple of years. Of all the widely available materials, composite sinks like quartz or granite are preferred in many homes today. This is due to their virtually stain-proof, heat-proof, impact-resistant, and scratch-proof surfaces.
Composite sinks really don't require super harsh cleaning products to keep them looking clean. Whilst they are generally more durable and resistant to scratches, it's also best to avoid particularly abrasive cleaning products or methods.
Yes, composite sinks can withstand boiling water. There is no issue with pouring hot water down a granite, quartz, or solid surface sink.
On a lighter-coloured sink, you can use bleach diluted with water (50/50) to scrub the stains with a nylon brush. Rinse with clean water after cleaning. Most of the time, you will find that a quick rinse after use is enough to keep your composite sink clean.
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.
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.
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.
'The easiest kitchen sink material to maintain is going to be one made of stainless steel, copper, cast iron or enamel because they will not support microbial growth as they are not cellulose material,' says Darren Hudema, director of training and technical services at PuroClean.
1. Stainless Steel. When choosing your kitchen sink, you pretty much can't go wrong with stainless steel. This top kitchen sink material is extremely durable and able to withstand heavy drops from pots and pans while also resisting scratches from sharp knives and utensils.
Quartz Composite
Best for: High durability, heat-resistance, and sound dampening. If the vulnerabilities of solid surface acrylic resin or enameled kitchen sinks are concerning, then a quartz composite kitchen sink is a great option.
When compared to wrought materials, composites are more brittle and more easily damaged. There are some issues with their repair. For instance, materials need refrigerated transport and storage. Similarly, special equipment is required for hot curing in many cases.
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.
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.
Stain Resistant: Unlike natural granite, this non-porous material requires no sealing and will keep from staining by design.
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.
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.
EASY MAINTENANCE: Black sinks, especially those made from granite or quartz materials, are easy to clean and maintain. They do not show water spots or stains as easily as white or stainless steel sinks.
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.
Instead, it recommends bleach, Soft Scrub and a Scotch-Brite pad and warns not to leave the cleaners on the surface for more than 15 minutes. "There are certain acidic compounds such as coffee and spaghetti sauce, etc.
For daily care, all you need to do is to rinse the sink out thoroughly after each use. If you have a dark coloured sink and are concerned about water spots, you can use a lint-free towel to dry the sink after each use as well.
