Question

How do I clean blue-green stains caused by a dripping tap?

Brad Bane

Community Answer

Most corrosion problems show up as blue-green staining. The stain is copper deposited from the corrosion of the water piping and fixtures. The corrosion will eventually cause pinhole leaks in the water pipes. The most likely cause is low alkalinity, which typically results in low acidic (low pH) water.

Question

How do I remove the gritty dirt left on a porcelain tub from a bathmat that was left on bottom for a long time?

If you have any tough-to-remove stains on the tub, cover them with salt and squeeze the juice of half a lemon on top. Or, you can try two parts baking soda and one part hydrogen peroxide set on a stain for about 30 minutes. Use a clean cloth or sponge to scrub the salt mixture into the stain and remove it.

Question

I have yellow residue in my bathtub, what is best way to get rid of it?

Stephanie Atilano

Community Answer

For yellow stains, use vinegar. For yellow stains and soap scum, vinegar will do the trick. This is the preferred bathtub stain remover, to use on the delicate surface of an acrylic tub.

Question

How do I remove pink hair dye from a porcelain tub?

Maverlie Carey

Community Answer

To remove hair dye from a tub, fill it with hot water until it covers the stain. Add a cup of vinegar and mix, then add half a cup of baking soda (it will fizz). Let it sit for about 10 minutes, and repeat if necessary.
