How To Clean Stainless Steel Sink Hard Water Stains?

Nothing can beat the beauty of a shining and gleaming stainless-steel sink in your kitchen. It literally glams up and lightens the whole space. However, there are some issues that you are likely to face even with a great sink made of stainless steel.

The most common one is hard water stains. When you use the sink for daily needs, some lime and other minerals in water tend to leave white spots on it.This basically appears after the moisture drying out. The matters can get worse if you are recycling the RO waste water. The stains tend to be worse in such cases since the RO waters have high TDS levels, refer to  for details on this topic.

If not taken care, the sink might gradually damage and you’ll have to think about replacement. Nobody would really like it. So, the best way to avoid such hassle is by maintaining and cleaning on a regular basis.

Get Rid of Hard Water Stain from Stainless Steel Sink

Let’s talk about removing the white spots from your stainless-steel sink. I’ll tell you a process to get back the lost shine and say goodbye to that ugly spot.

Get Some Stuff

The most common thing that many homeowners these days use is a Water Softeners. It has some amazing chemical formulation that easily gets rid of such hard water spots in no time.

However, I believe some homeowners won’t want to put chemicals and harsh elements on their lovely farmhouse-style stainless-steel sink. So, they look for homemade solutions that can easily get rid of such spots.

There are quite a few cleaning recipes using vinegar, baking soda, and water. I’ll talk about it in later sections. For now, just get a good pair of gloves, scrubber, sponge, fabric and a bowl with water. Also, get some Brasso for polishing.

Dry the Sink

  • First of all, wear the rubber gloves you just got yourself. Make sure they have no hole at all. Now putting glove pair, simply start the cleaning process.
  • You need to wipe the stainless-steel surface using a soft clean cloth. Let it become completely dry and moisture-free.


Pre-polishing for Easy Clean Up

  • For this process, you’ll need a store-bought product like Brasso. You can also try a similar natural ingredient for the purpose.
  • Once you get a store-bought version, make sure to read the instructions well. You should also do a simple patch test on a small portion of the surface. If it’s safe, proceed with complete polishing.
  • Use a drop of Brasso on a cloth. Now use this cloth to rub the spot with a gentle hand.
  • Sometimes, the stains come off at this point and you don’t need to go further. You can simply polish and clean the area to finish off.
  • Make sure there is no product left on the surface. If the spot is still visible, go for next steps.

Kitchen Cabinet Recipes

Your kitchen cabinet already has some mind-blowing cleaning ingredient that does amazing job for hard water stains.

Baking Soda & Water

  • Get some baking soda and water. Now create a creamy paste mixing them well. Make sure you don’t get the consistency too runny or thick.
  • Now use a brush or hand to spread the mixture all over spots. Use a soft sponge or cloth to rub the area gradually. Never apply too much force. Go with a circular motion for cleaning it safely.
  • If the stains are not too hard, then avoid using any harsh sponge or steel wool. These might leave ugly scratches in stainless steel.
  • Once you have applied the whole mixture, use some cool water to rinse it off. Thoroughly wipe and dry it out.
  • Your sink should shine without any spot. You can also use this solution to get rid of greasy food from your stainless-steel sink.


  • Another effective ingredient is vinegar. It is an old and great element to remove spots from stainless steel material. The acid level of vinegar is trusted for centuries to clean stainless-steel sink. It literally disinfects that whole surface and keeps it germ-free.
  • Use a similar ratio of vinegar and water. You may want to put a little bit more vinegar if the spots are too hard.
  • Now let this solution spread evenly over the spots. Keep it that way for the whole night. The solution will probably create bubbles and frizzes.
  • Next morning, simply rinse it with cool water and blot dry the area. You should find a shiny, sparkling and spot-free surface.


Extra Sparkling Sink (Optional)

  • After such cleanup, you may want to try a bit more for an extra glowing and sparkling look. If that’s the case you may want to try this optional step.
  • Simply use some olive or baby oil for this purpose. Get a clean white cloth and pour a few drops of oil in it.
  • Now use this cloth to gently buff the surface of your stainless-steel sink. Do so until you get a satisfying sparkle on your sink. Make sure to use lint-free cloth for this step.


Common Tips for Stainless Steel Sink

Just don’t let your sink be wet for a long time. Regularly wipe and keep it dry to avoid rust marks and hard water stains.

Don’t let any waste or liquid sit for too long in your sink. Always have a light and simple clean up habit after each use.

If you are using a store-bought cleaner, never work barehand. Wear some rubber gloves.

Don’t even think about mixing cleaners. This could be enough dangerous to completely ruin and damage your stainless-steel surface.


You’ll never have to go through such cleanups. If only you care enough to maintain your stainless-steel sink right. Yes, I know we all lead a very busy life and sometimes a simple rinse-and-wipe step gets missed out due to so.

I’m completely aware of your situation and to be honest, that’s something we all deal with. But still, try to have some regular clean up regime.

So that in the long run, you don’t have to spend a whole amount of money for replacing your sink. It may be a bit irritating now but so much more helpful than dealing with hard water stains.

I hope you’ll use this technique and get rid of the ugly stains just like that. However, if the sink still seems stubborn with no changes, go for professional cleaning services. Sometimes it also ends up with a replacement. Good Luck!
