Re: hard water stain remover
for calcium deposits sa toilet bowl, use muriatic acid.
Re: hard water stain remover
Hi there...
The reason i didnt' recommend muriatic acid initially is because it is hydrochloric acid (+30%) and water. Yes, it can remove lime or calcium deposits, but it will also pose additional harm to anything inside your bathroom, aside from burning your lungs. Fumes that will evaporate is acid and when it contact moisture in the air, a hydrochloric acid is again formed. If you decide to use, be carefull and neutralize immediately all stainless/metal fittings, from acid (fume) contact inside your bathroom.

For vinegar to be effective against hard water stains, its a weak acid and has to be left to stand for some time I believe. It has to have time to eat away the deposits. You could put vinegar in a spray bottle, or get an old dish rag and fully soak it in vinegar. For faucet fixture and the like, wrap the rag around the fixture so its constantly in contact with the vinegar. Leave overnight for best results.

Hey folks, glad to be back after months of hibernation!!
Am not sure of TURCO's formulation. All i know is rust converter has phosphoric acid and tannic acid. Each has its own unique function in the metabolism of iron salts. I will be back, will consult with my chemist friends.
Re: hard water stain remover
clarification re the vinegar suggestion, will this also work (babad overnyt or longer) on plastic fittings? changed bath and kitchen faucets to the plastic type para sana maiwasan yung hard water stains kaya lang may stains pa rin.

Re: hard water stain remover
has anyone any experience in removing hard water stains from the (external) side mirrors of a car ??
Mine has fantastic stains so much so that it is always unclear (blurry).
And since the mirror itself is movable (there is a motor & controls that focus it) and therefore quite breakable, what is the best way to remove the stains specially if it needs a vigourous rubdown ??
Cheers 🙂

If you are not comfortable using chemicals, try Scotch-Brite Eraser pad. Not sure if there are local retailers but I was able to purchase similar product (in Japanese packaging) at DIY. I was able to clean my glass windows from soap scums and hard water stains. Good also in cleaning my car windshield and whitening my monobloc chairs.
Re: hard water stain remover
yes UP shopping center and the previously know coop or dilimall are one and same. they also have boric acid there. btw, 1kg phosporic acid is around P235/kg the last time i bought, october last year.
Phosporic acid is also available at Neco, Masangkay St. walking distance from Recto Ave., price is 173 pesos/ltr. I just bought a gallon. Check their website for their other chemicals like citric acid, boric acid.....They are popular for food coloring liquid.
