Got stains that won't come out of your sink? Use nail polish remover on a cotton ball and it will come right off, no matter what the stain.

Got a stain on your tub or sink? Clean them quick and easy. Add cream of tartar and hydrogen peroxide and make a paste. Spread the paste over the stain and scrub lightly with a brush. Let the paste dry and then wipe or rinse it off. That's it you're done. No back-breaking work here! Hope this helps. Take care of you and those you love.

Editor's Note: There are health concerns about mixing bleach with other cleaners, like vinegar. Please use caution and avoid breathing in the toxic chlorine gas.

I am not at all proud to let you see the mess I let my kitchen sink get into. I am kinda happy to let you in on how I cleaned it up.

My sink is old and pitted, just like me. The deeper the pits and the more the smooth surface has been worn away, the more difficult it is to clean. Not only that, these older sinks with their eroded surfaces, stain more easily and hold onto those stains, tenaciously.

Erosion and pitting cannot be cleaned away. If you are bothered by these two, your only recourse is to have the sink re-glazed or to buy a new sink.

The biggest offenders to a sink's surface is not protecting the bowl bottom with a mat, and believe it or not, cleaning the sink with scouring powders specifically designed for cleaning porcelain sinks. These cleaning agents, including the 'soft scrub' type, will in time etch the sink surface, making it porous and open to real staining. By the time you notice the dulling of the surface, the permanent damage has been done. My sink was not new when it came into my possession. Had it been, its surface would not be in the shape it is.

There is a product called Barkeeper's Friend. My understanding is that it is of a totally different composition than regular scouring powders and therefore much gentler to a sink's surface. I cannot speak to its effectiveness or gentleness. I have not used it. I can speak to its cost. It is not moderately priced.

Seeing what a mess my sink was in, I decided it was time for some serious cleaning. While getting out my cleaning supplies, I happened to remember something.

My home is covered with vinyl siding. The north side develops a heavy green layer of scum. This scum is very difficult to remove. I mentioned this to a sister, who suggested I try something she had heard about. A painter had said that the easiest way to remove this scum was with a mixture of equal amounts of household bleach and white vinegar. Doubtful, I tried the suggestion. It worked better than anything I ever tried. I even took pictures, I was so happy with the results. A tip within a tip. One you might want to remember if you have vinyl siding.

I always use bleach when cleaning my sink. First, I scrub the sink with a paste of dish detergent and baking soda. This will never dull a porcelain surface. After rinsing the sink, I pour in bleach and let it sit for a while. The sink is then much whiter and sanitized.

Well, I wondered if a combination of bleach and vinegar would clean and whiten the sink better than bleach, alone. I can tell you emphatically, it does.

I cleaned the sink as usual with dish detergent and soda and then rinsing. Then, I poured in the bleach-vinegar mixture. I could tell immediately it was whitening better and faster than bleach, alone. It even lifted some of the rust stains.

For the deeper rust stains, I used something I discovered long ago, a pencil eraser. Unless the rust stains are really deep, the eraser will remove 100% of them. Don't go out and buy a big block eraser. It won't work. The older and harder the eraser, the better it will remove the rust. It will not harm the porcelain. Expect to use some elbow grease if the stains are deep. A good use for those old pencil stubs you're meaning to throw away.

A quick rinse and another application of bleach-vinegar if you think it necessary and you finished. You will note that I did not remove 100% of the rust stains. I came close. By next Saturday, I will have found more old pencils and finish the job. I still have the other bowl to do, too!

Final tip: Never use anything harder than baking soda on porcelain sinks. That includes those newer, flat nylon scrubbing sheets. They will etch the sink surface.

There are concerns with mixing vinegar and bleach together, just as there are for ammonia. Here is a warning I found in a PDF from the Health Department

"Mixing hazards: USE ONLY IN WELL-VENTILATED AREAS. Adverse effects of inappropriate mixtures of household cleaners usually are caused by prolonged exposure to an irritant gas in a poorly ventilated area. The most common inappropriate mixtures of cleaning agents are bleach with acids (like vinegar) or ammonia (Windex ®). Potential irritants released from such mixtures are chlorine gas, chloramines, and ammonia gas. "

Definitely be sure to have the space well ventilated and it would probably be best to wear a mask as well.

Here is a link I found with more complete information:

I use Electrosol liquid dishwasher detergent. It completely removes all stains and deodorizes the sink. My sink is white composite material, and comes up like new every time.

I use either Bon Ami or Bar Keepers Friend. You can purchase both by the Ajax and Comet cleansers in your grocery store cleaning products aisle.

Please dont use cleanser on your new sink. I did that when mine was new 30 some years ago and have since learned it takes the finish off the sink. I use Tilex for stubborn stains in the sink. Just spray the sink, let set for about 20 seconds and rinse.

Also, a friend of mine suggested I try baking soda to clean my stained bathtub. I didnt think it would work as I'd scrubbed and scrubbed with Comet. I tried it and she was right. Sometimes baking soda can clean better than cleanser!!

Once you get your sink clean you may want to consider putting paste wax on it to keep it that way. Water beads up and it shines. The wax also protects the sink. I'm wondering how Rainex that is used for car windshields would work... hmmmm

Best of luck,

I'm going to try some of the other users' suggestions. I've used Restore-4 for porcelain, and it works well. Just a note though - it stinks! Open your windows. Make sure sink is completely dry before spraying it on with a spray bottle. Let soak for 15 minutes, then scrub with a scrub brush. It's a pain, but it works.

My wife likes to use Windex to clean everything! Well, she was cleaning the guest bathroom sink and there was an area where the porcelain enamel had rubbed off unbeknownst to her. Once the spray hit that spot, it absorbed the blue spray and now there is a big discolored blue spot where the enamel had rubbed off. Does anyone have any suggestions how I can remove the stain? Any help would be greatly appreciated.

I have a friend that has two yellow stains in his sink (each about three inches in diameter) that will not come off. We do not know the source of the stains as they were there when he moved in. He has tried bleach, baking soda, lemon paste, and Soft Scrub all to no avail. Any suggestions?

If the porcelain surface is in tact it is unlikely the sink itself is stained. Have you tried a mild abrasive cleaner? Or try filling the sink with water, adding bleach and leave overnight.

I would try mechanics hand cleaner, the goop in a jar that gets motor oil and grease off your hands. It is available at the auto parts store. Put some on a rag or paper towel and rub it into the stains. Wipe clean with another paper towel or rag and see if it is gone. Repeat as necessary. Hopefully that will dissolve the oil so it comes out.

Well, we are deisel freaks here and teh only thing I use on grease any where any time gets it ever time from carpet to refridgerator door handle to teh knobs on the tub and the faucet in the sink and everything in between..... DAWN (the old blue kind not with any lotions or oils or scents) dishsoap and a little sponge and water..... I am often ask by others in our trucking field how we keep teh clothes and carpet and driveway and tools and selves clean from the grease.. I jsut smile and say DAWN. I leave a bottle in the bathroom at all times so he and I can wash with that instead of bar or liquid soap. the grease just lingeres with everything else!

Dollar general store still carries teh old blue kind I have come to know and love for still only a dollar a bottle. wallmart I think has it for 97 cents. and if that doesn't work let sink dry completely rub a genours amount of WD40 on all effected areas rub it in to the stains..... this will loosen teh stains , Now use the DAWN and it will come out. Good luck.

I have used hand soap dispensers on my porcelain bathroom sinks. Unfortunately, they have left yellow circles/rings on the sinks now. I have tried many things, but I just can't find a solution to remove these stains. Please help. My bathrooms are only 3 years old. Thanks.

If the stains are on the sink itself like my stains from soap dispensers are try using dishwasher gel. Put some on the area, with a rag rub it in, let it sit a bit and then rub and rinse off. This is all I ever use to clean my sinks and tub after wondering one day why the side of the sink the dishwasher drained on was always so clean. Sadly, I no longer have the dishwasher, but I do have my gel to clean with. I use a store brand, but any kind should work.
