Re: hard water stain remover

mayroon akong nagamit to remove acid rain marks sa windshield, bought it at handyman, it's in a glass bottle w/ glass cleaner marking, color blue liquid, forgot the brand name, a friend borrowed it, naubos niya, pero effective!

Re: hard water stain remover

To remove water stains on your bathroom fixtures especially the chromed ones...Use vinegar.

Re: hard water stain remover

oo nga meron ba off the rach na product, tried using vinegar, walang effect, kasi deep well kami dito kaya meron mga hard water stains, hinde matanggal ng maid kahit anong linis gawin eh

Re: hard water stain remover

deep well din ang water sa amin, sa tiles i,ve tried many brands second to the last was turco rust remover, sample ako kaunti, it was effective, disadvantage is pati grout tanggal, and the smell di ka makatagal. the last i've tried very effective din was sandpaper grit 60 yung cloth type, tanggal talaga, disadvantage is masakit sa kamay, try to send picture, before and after, sa mga bathroom accessories wala pa...

Re: hard water stain remover

wala problema sa amin sa flooring tiles, sa toile bowl lang talaga, I wll try the sand paper nga..thanks

Re: hard water stain remover

I guess these are calcium deposits, and if my chemistry is right, an acid should remove it ?? There are different types of 'household' acids (different strengths).

Keep the acid in contact with the stain by applying it liberally and/or repeating the procedure.

Using sand paper to mechanically scour the tile could do the trick but you end up with a 'scoured' (scratched & non glossy) appearance. Use the finest grit sand paper (2,000 grit ??) you can get and maybe it might work all around !!

Yuck, I wouldn't want to get my hands in the innards of a toilet bowl !! 🙁

Do keep us posted on how it panned out !!

Cheers 🙂

Re: hard water stain remover

This might help, we've been using this to de-scale our hotwater line out-of-lime deposits. Phosphoric acid, apply gradually over affected area (cremics, tiles) then flush with water.

Re: hard water stain remover

where can u buy phosphoric acid?

Re: hard water stain remover

if you are near UP Diliman, try going to the shopping center and look for B.E. Supplies. They sell in small quantity, practically all chemical supplies, intended for students.
