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. Dry the sink after use to delay future build up.
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.
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.
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.
Spray vinegar on the entire sink surface and let it soak for 30 minutes. You can place paper towels on the sink to allow the vinegar to stay soaked on the sink surface. After 30 minutes use a brush to scrub, and then rinse off with water.
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.
Removing Stains and minor scuff marks
Rinse well. Also, the use of Bar Keepers Friend (directions included on bottle) will help remove stubborn stains. Finally, clean with BLANCOCLEAN to put a protective coating back on the sink's surface.
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.
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.
Avoid substances like bleach and harsh chemical cleaners as this could damage the surface of your sink and cause staining. Chemicals to avoid include ammonia, sodium hydroxide, hydrochloride and sulphuric acid.
Mineral deposits can lead to discolouration, which you can remove with proper care and attention. It is important to note the following when cleaning your granite composite sink: Do not use full strength bleach or cleaners with ammonia. Do not use chemical drain openers.
Yes, composite sinks can withstand boiling water. There is no issue with pouring hot water down a granite, quartz, or solid surface sink.
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.
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.
Clean the heck out of the sink, then clean it again with rubbing alcohol. Soak/dip the cups in hot water to make them more pliable, then apply a little petrol jelly around the cup.
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.
As with all types of sinks, granite composite kitchen sinks are heat resistant. However, they are not heat-proof, and cannot withstand extreme temperatures such as a hot pan taken off the hob and placed directly into the sink. The acrylic resin in the mix of a granite composite sink could warp or melt.
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.
Durable — Owing to its mineral content, composite sinks are very hard and durable. As a result, they are unlikely to chip, dent or scratch and generally handle everyday wear-and-tear well.
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.
