Bar Keepers Friend should remove most stubborn stains with multiple cleanings. If you continue to have trouble, use a mild abrasive cleanser, along with a soft scouring pad. For more stubborn stains, a solution of 50% bleach, 50% water can be used, but only in these situations.
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.
Deep Clean
For a more thorough clean, sprinkle baking soda over the whole sink, then spray with a 75/25 solution of white vinegar and water to create a fizzing solution. A gentle scrub with a soft sponge and an old toothbrush is enough to give your sink a thorough clean.
You can usually use mild dish soap and warm water to clean a granite composite sink. For tougher stains, sprinkle baking soda into the sink, add vinegar, and gently scrub with a non-abrasive sponge.
Hard water (rain is soft) is the presence of calcium, magnesium, lime and iron in drinking water. The microscopic iron particles, upon mixing with oxygen, form iron oxide and cling to the surface of bathtubs and sink. As they build up, they create an orange or brown stain.
Brown water can be caused by the corrosion of water pipes as materials flake away and find their way into water supplies, making the water an orange-brown color (from iron pipes) or even black (from lead pipes). Certain elements from sulfur dioxide can cause water to turn brown when combined with hot water.
Light brown or tea-colored stains: Usually caused by manganese. Manganese is also a common component in the Earth's crust and is also found in many ground waters.
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.
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.
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. Aluminum cookware can scratch the surface of the stone.
Since granite countertops have a sealant on them to keep them shiny and stain-resistant, you want to avoid using anything too acidic or basic on the granite. Frequent use of vinegar, Windex or bleach will dull the granite and weaken the sealant. Instead, a little soap and water should do the trick.
While it's not generally wise to use abrasive cleaners on your natural stone countertops, you can safely treat stubborn hard water stains with a paste of baking soda and water. Simply apply it to the affected area and scrub it with a soft-bristled brush, then rinse with water and dry with a microfiber cloth.
Granite Sinks: What to Know
In addition, it is very important that you never use harsh chemicals such as bleach in an attempt to clean your granite sink. Using harsh cleaning products, including many multipurpose cleaners, can cause damage to natural stone surfaces.
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.
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.
Stain Resistant: Unlike natural granite, this non-porous material requires no sealing and will keep from staining by design.
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.
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.
Stain Removal:
Make a paste of baking soda and water. Apply the paste to the stain and let sit for five minutes, then rinse off with a soft cloth. Baking soda is a mild abrasive, so don't scrub. Repeat if necessary.
When dissolved in water, iron and manganese typically leave rust-orange or black stains in sinks, bathtubs, toilets, and any other household appliance that uses water. These minerals are found in many water sources distributed throughout homes.
You can eliminate brown water from your home for good by running cold water from your tap for at least 20 minutes. If the water is still brown after this, contact your city's utility provider and request that they flush out the brown water with a fire hydrant. If the problem persists after this, call the professionals.
