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.
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.
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 you need to perform a deep clean due to deep stains - use a homemade mixture of baking soda or white vinegar (either is good, just make sure it's a small amount) and combine it with water. Add this mixture to a soft cloth or a brush with soft bristles to tackle the harder stains.
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.
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.
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.
Stains can be easily removed if you are proactive. You can remove the stains by using a poultice or a paste. The particular ingredients that make up the poultice will depend on the type of stain. Never attempt to clean the countertop or remove the stain using harsh products like bleach.
Mix a poultice paste of baking soda and water (for oil-based stains), or baking soda and peroxide (for others), until it's as thick as peanut butter. Spread the mixture over the spot, cover it with plastic wrap that you've poked a few holes in, and secure it with masking tape. Let the poultice paste stand for 24 hours.
Stain Resistant: Unlike natural granite, this non-porous material requires no sealing and will keep from staining by design.
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.
Use Soft Scrub with Bleach Cleanser or Soft Scrub with Bleach Cleaner Gel to free your sink of soap scum, dirt, and stains.

Use a moist sponge to make the inside of the sink slightly damp. Sprinkle baking soda over the stain until it is completely covered. Use a sponge or cloth to gently scrub in small circular motions until the stains are gone.
To clean an oil-based stain, make a baking soda paste with water. If you're dealing with a water-based stain, mix the baking soda with hydrogen peroxide. Apply the paste generously over the stained area: Gently scrub the counter with a soft cloth and rinse thoroughly. Repeat as needed.
Some DIY resources claim vinegar will work as a household cleaner for natural stone, but this information is incorrect — vinegar is acidic and can harm your granite's sealant. An expertly sealed granite countertop should last your home for years with proper care.
Vinegar is made up of acids that can severely harm your granite. Even if it is diluted, vinegar may still leave acids on your granite countertops. This can cause your natural stone countertops to etch. You can tell that your granite countertops have begun to etch by seeing a small ring or some sign of a watermark.
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.
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.
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.
Quality composite granite sinks are formed under high pressure, making them nonporous, hygienic, and resistant to heat, stains, scratches, and chips. However, cleaning and removing stains from a granite composite sink can be tricky.
