How can I remove stains from a stainless steel sink?

Buy and install a new stainless steel sink.

Look on the package of the disinfectant cleaner. There should be some phone numbers for the company's customer service department. Call them and ask the question. They'll know what best works to counteract their product.

if it contained chlorine it may not be possible. Chlorine is one of the most powerful oxidiing agents out there. If the SS is pitted then itll have to be resurfaced by using emery wheels on an angle grinder.
Start with 200 grit and go up to 1200 as you get a smoother surface

I always use this stuff called CLR, that will take out most stains, at least for me it has.

Im thinking that these aint stains this dude is talking about but "Pits" that could very well happen of one left a chlorine agent in wet contact with the metal or porcelain.

Yikes! sounds like he will need a new sink

naah, the stainless steel sinks can be resanded and look pretty good. Just that th Rockwell numbers of stainless tend to be not so high that it can be sanded , but one needs to be careful

One could also stain the rest of the sink to match, if it's not pitted.

Hello Community,

Extra care must be taken when cleaning a stainless steel sink. Stainless steel can scratch easily if steel wool or some scouring powders are used, and harsh chemicals, such as bleach, can damage the color and even cause pits in the surface. The best cleansers to use are non-abrasive and non-toxic and they won't break your budget because they can be found right in your refrigerator and cupboard. Here are some instructions for removing stains from a stainless steel sink.

1. Cut a fresh lemon in half and rub the cut side on the stain in your sink. Different stains respond to different treatments, so if the lemon doesn't work, there are other options you can try to remove the stains.
2. Leave the lemon juice on the stain and sprinkle on a little common table salt. The two elements together have a light bleaching action, yet it's non-toxic.
3. Wet the surface of the stain with water and sprinkle on a little baking soda. This works as a non-abrasive scouring powder. Rub with a damp soft cloth.
4. Place the stopper in the sink's drain and pour some white vinegar on the stain. Let it sit for 30 minutes. If the stain is even more stubborn, heat the vinegar on the stove top or in the microwave and pour the warm vinegar on the stain, again allowing it to sit for 30 minutes.

Hello Community,

Cleaning stainless steel can sometimes seem tricky, but is a very resilient surface. When problems happen, it is best to start with the basics to help repair the surfaces. Baking soda mixed with liquid dish soap can make a good paste to gently rub on stains. Be sure to rinse the stainless steel surface thoroughly, and towel dry. If the stains still remain you can try vinegar. Remember to thoroughly rinse and towel dry. If stains still remain I recommend trying a stainless steel cleaner and polisher. Barkeeper's Friend is a good powder formula that can clean without scratching. Be sure to follow the directions, rinse thoroughly, and towel dry. These methods should help remove the discolorations.
