Tip: Boraxo or Limeaway For Porcelain

I too have had problems cleaning, here in Hawaii, my porcelain tub. I have been researching it for a month now. I have come across some very good cleaning agents for your porcelain, old or new. It is Boraxo or Limeaway

I've tried Lime-A-Way and it works. Lately I've found different kinds of stains on my old porcelain sink and will try Boraxo next. The sites I've found say they work great. The taste of water in Hawaii has changed and there are green stains on my plumbing which suggests minerals in the water, thus the stains on the sink. Good luck and great cleaning! Thanks.

Coffee cups stained with coffee? Make a thick paste with simple table salt and warm water and use a soft rag and wipe the coffee cup inside and out with the salt paste. Sparking new!

Question: My Dirty, Old, Pitted Tub! Keeping it Clean

I have a very old, pitted porcelain bath tub that I can't afford to refinish or replace. It collects a lot dirt in the pits and I cannot get it clean. it no longer shines at all! It isn't stained, just has hard to remove dirt. I have done the bleach thing, Comet, various cleaners, even some from the janitorial supply house, throughout the years but nothing seems to work (scrubbing bubbles is the best) I have tendonitis in my arm and cannot scrub for long periods of time. If I do get it clean is there an economical finish or wax that I can use on it so it stays cleaner longer? Thank You!!!

    The blue and green stains are likely copper from your pipes dissolved in lime from hard water. Vinegar may remove the stains, or any product advertised for cleaning up lime residue, such as CLR or the CLR Tub and Tile cleaner.

    I had one in my kitchen sink. When my sister-in-law saw it, she suggested that I put the sink stopper in, pour 3-4 cups of Chlorox in it (enough to cover the bottom), add a couple inches of water and let it sit over night.

    It worked. The sink was sparkling white when I drained it out the next morning. I've done the same thing every few months when I notice it getting stains in it. Chlorox definitely pulls the stains cleanser doesn't.

    If you don't want to pour a whole container of Chlorox in your tub, possibly soaking an old rag in it and put the rag dripping wet (do not wring it out) on your stain and leaving it overnight might work.

    Pour straight vinegar on it, or line with vinegar soaked paper towels, and remove the towels and wipe up loosened deposits before the towels dry. Re-wet if needed. (09/07/2006)

    Zud Cleanser works well on porcelain tubs, but don't leave it on for any length of time. Scrub, then rinse thoroughly.

    How would I remove hard water and rust stains from my old porcelain bath tub? It's from the 1920s, so I don't want to replace it. I've tried using advertised cleaners, but they start to strip away from the tub and leave behind the stains. Does anyone have an alternative?

    RE: Cleaning a Porcelain Tub

    If you've tried most everything imaginable to remove the stains, you might want to consider hiring a professional to refinish your 1920's bathtub. We had a porcelain bathtub refinished in our second house. It should be refinished during the warmer weather so if you have a window in your bathroom it can be opened to let out the toxic fumes.

    Look in the yellow pages under bathroom fixtures/bathtub refinishing. Or go to:

    How do you clean an old, scummy porcelain tub?

    RE: Cleaning a Porcelain Tub

    Spray with engine cleaner. The kind you buy at AutoZone. You may have to do it more than once, but it will get it cleaned and shining. I remember when I was young an old man who cleaned tubs did this and it worked, made an old nasty tub shine like new. (05/06/2010)

    RE: Cleaning a Porcelain Tub

    Use Dow scrubbing bubbles. Spray it on, let it sit for a few then wipe off. You may have to repeat a few times, but it works well. (05/07/2010)

    RE: Cleaning a Porcelain Tub

    Put in two or three cups of baking soda and a little liquid detergent, such as Dawn and fill with hot water. Let stand for a couple of hours then scrub with a long handled brush (saves bending). Hopefully this will take care of the problem. (05/07/2010)
