Review on Hard Water Stain Remover with Drill Pads - Shower Door Cleaner by Bring It On Cleaner by Shane Grosland

We have very hard water and I've tried everything to clean our shower glass with no success, well. so far. I wet the glass first, plus I wet the pad, then I applied the cleaner to the pad and started cleaning. If your pillow is really wet it will get a little dirty but it's worth it. I worked in 2 x 2 foot sections, starting at the top and working my way down. You should continue to wet the pad (and/or glass) and reapply the cleaner, but a small amount of cleaner will do. When I was done I rinsed everything off and bought a shower mop to wipe it all down. Once it dries you can tell if you missed anything (which I did) and you can easily get into the little spots you missed. I use a mop after every shower to keep water from collecting on the glass. Make sure you use white pads on the glass and NOT red ones. Red is more natural and may scratch it. I've even used white in my porcelain sinks and they've worked great. I highly recommend this product as it does what it can.
