Bruce's GSR Cleans Water Spots

[Bill Shaheen]

After several days of trying every concotion imaginable to remove the hardwater deposits from our glass block shower stall, we tried Bruce's GSR Glass Water Spot & Stain Remover, which I found at the local ACE hardware.

Also found their website:

Used with 0000 steel wool, it removed the spots entirely, albeit with a couple passes of heavy scouring. But, it was a 5-year buildup.

I suspect the mineral deposits may have actually been etched into the glass and that in fact I was polishing a layer away, rather than removing a deposit.

At any rate, the glass looks terrific.

How can deposits be etched into something?

[Phisherman]

Ouch! Steel wool will scratch glass. An acid or CLR should have dissolved the deposits. You could scrub glass with a nylon brush or net without concern about scratches.
