After 30 minutes use a brush to scrub, and then rinse off with water. Once done, apply mineral oil (or baby oil or olive oil) to the entire sink surface. Using mineral oil regularly on the sink surface will prevent hard water and mineral deposits from building up on the sink surface.
After you have cleaned the stain, you can use a small amount of mineral oil to restore your sink's shine.
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.
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.
You can use Mr. Clean Magic Eraser, then thoroughly rinse with dish soap and water. You can then apply mineral oil on the sink once dry to bring back its dark sheen.
Once done, apply mineral oil (or baby oil or olive oil) to the entire sink surface. Using mineral oil regularly on the sink surface will prevent hard water and mineral deposits from building up on the sink surface.
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.
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.
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.
Don't worry if the mineral oil leaves a mark. Even if your counters need to be sealed, the dark spot from the mineral oil will evaporate in about 30 minutes.
Cooking oil
Any typical oil will work, for example vegetable or olive oil. Apply a small amount of oil to a soft, clean cloth, and buff the granite using circular motions. Don't forget to polish the edges of your counter! Oil will give your granite a nice shine, and also help it repel water.
Lemon essential oil is another excellent option for cleaning and adding shine to your countertops. This oil, unlike lemon juice, does not contain any citric acid, making it safe for granite.
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.
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.
Stain Resistant: Unlike natural granite, this non-porous material requires no sealing and will keep from staining by design.
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.
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.
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.
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.
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.
