The composite material is easier to clean and won't require constant babysitting, which makes it a better choice for households with children. The low maintenance cost of a granite composite sink makes it ideal for households. This means that harsh cleaners can damage the surface of the 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.
Stain Resistant: Unlike natural granite, this non-porous material requires no sealing and will keep from staining by design.
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.
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.
Hard water and minerals in the water can leave white stains on your sink. 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.
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.
'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.
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.
Yes, composite sinks can withstand boiling water. There is no issue with pouring hot water down a granite, quartz, or solid surface sink.
CLEANING of GRANITE COMPOSITE SINKS
Generic stains should be removed immediately. Cleaning powders and creams which are even slightly abrasive should not be used, nor chemically aggressive detergents.
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.
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.
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.
Team the clean modern lines of a contemporary kettle tap with a stainless-steel sink, composite kitchen sink or a modern ceramic sink and fuss-free cabinetry. If your kitchen has country or period style, or a Belfast-look sink, classic boiling water taps have an elegant detail that will pull the look together.
Porcelain, ceramic and fireclay kitchen sinks have extremely low water absorption characteristics (making them easy to keep clean on a regular basis).
Stainless steel sinks are very low maintenance; they are corrosion and rust resistant, and as long as they are cared for properly and wiped down after every use, they should not stain. Find out more about how to clean a stainless steel sink by reading our guide with handy tips and tricks from our experts.
Stainless steel has long been a material of choice for its hygienic properties, resistance to stains, rust, and corrosion, and affordability. But it is not the only metal on the market; copper and brass sinks can be used to make a design statement.
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.
Composite quartz sinks are some of the most solid and robust sinks available with a superior resistance to heat and scratches. Combining their hardwearing build with a stylish design, they offer fantastic value for money and superior resistance.
Best for: Affordability, durability, and low maintenance. The most common option for a kitchen sink material is stainless steel. This material is well-known for its water-resistance, durability, and scratch-resistance, and is also often recognized for superior rust-resistance and antimicrobial properties.
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.
