Sprinkle baking soda or Borax directly on the hard water stain in your sink, then spray on the same vinegar and water solution you used on the bathtub. Let the cleaners sit for 15 minutes, then scrub with a soft brush or sponge. (Remember to wear gloves when cleaning with Borax.)
Start by coating the wet sink in baking soda and adding a little dish soap and hot water to your sponge. Whenever you scrub a sink, start with the sides of the basin and work your way down, pushing any grime directly into the drain. Keep adding soap and water as needed or until the surface is scum-free.
Try cleaning your sink with a paste of baking soda and water. You can then rinse the sink with vinegar, which will bubble and fizz. Vinegar naturally disinfects while helping remove hard water stains from your stainless steel sink. Once your sink is clean and dry, you can easily add an extra shine.
Mix a solution of one part bleach to 20 parts water or around 180 ml of bleach for a gallon of water. Let the solution sit in the sink overnight and then drain it. Rinse off the sink with just water and dry it.
Bleach – just plain old bleach will work. Bleach really takes the sink back to original shiny white again. Wipe a small amount of bleach on your sink after rinsing away the bar keepers friend and dish soap and prepare to be amazed! White Vinegar – just regular old vinegar is one of my favorite all-purpose cleaners!
Use a Natural Cleaner
Begin by pouring up to a whole box of baking soda down the drain, depending on the severity of the slime. Then pour in the vinegar, up to half a bottle. You should hear or see the fizzing. Let it react for about five minutes, then slowly pour the boiling water down the drain.
Unlike chemical drain cleaners, hydrogen peroxide won't destroy your pipes and drains. It is safe for regular use so you can do a hydrogen peroxide flush once every few weeks to keep your drains and pipes in good shape. However, for more complicated issues, it is always better to call your plumber.
Make sure to use a 1:1 solution of distilled white vinegar and water. Spray it onto the sink, leave for a minute or two, then wipe and rinse. The solution shouldn't be left on the sink for longer because it can damage the stainless steel in the long term.
Put a cup of hydrogen peroxide in a spray bottle. Spray evenly over the porcelain. Let the hydrogen peroxide sit for 15 minutes to an hour. Rinse and buff with a microfiber cloth for a clean, bright shine.
Porcelain is a highly durable material for dental restorations, but it is not entirely indestructible. Stains will not penetrate the surface of quality porcelain restorations unless the porcelain has been damaged by: Highly abrasive toothpastes that wear away the outer glaze of the porcelain.
The brown stain is from a large amount of iron in your water. It is closely related to simple rust that you see on metal, which is iron oxide. Your water probably comes from groundwater that filtered through rocks containing iron-rich minerals on its way to the well.
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.
For white porcelain only, bleach can be used to remove stains; never use chlorine bleach in colored or vintage porcelain, as it can damage the finish. For both white and colored porcelain, liquid oxygen bleach (such as hydrogen peroxide) is a good alternative.
Hydrogen peroxide will gently brighten up a white sink. Fill a spray bottle with hydrogen peroxide, spray your sink all over and leave it overnight. The hydrogen peroxide will whiten and brighten your sink. Simply rinse and wipe the sink dry the next morning.
Stainless Steel
Be careful. The abrasive nature of the Magic Erasers can also scratch up the finish of your stainless steel sinks and appliances, especially if you use them and press down too hard. Too much scrubbing can cause the high gloss finish that seals most stainless steel appliances to break down.
Avoid cleaners that can damage steel and finishes. Instead, clean your stainless steel appliances with a dish soap like Dawn® Platinum. Its unique formula is tough enough to break up grease and grime while staying gentle on stainless steel surfaces.
Spraying the sink with an enamel-based paint will restore the luster of the finish. Avoid scrubbing the sink with any type of abrasive cleaner for at least a week.
Many homeowners ask if Magic Erasers® can be used on porcelain or if they will damage ceramic tile. The good news is that they can be safely used on ceramic tiles and porcelain, so you have nothing to worry about if you plan on using them this way.
The bathroom sink, especially a porcelain one, can tend to get quite nasty over time. You see a lot of discoloration around the drain and the overflow hole. Just apply the concentrate solution to both areas, let it sit for a few minutes, then scrub it with a cleaning toothbrush.
The best way to clean your porcelain kitchen sinks is by using bleach. Spread the cleaner on stains and let it sit overnight, then wash away in the morning. The stains in a porcelain sink can be removed using white vinegar. This method will also sanitize your sink and remove any harsh smells, making it clean again.
