Skyley Flexible Scrubbing Screen Cleaning Mesh for Household 5.5 x 4 Inch Cleaner Toilet Hard Water Ring Remover Scouring Pad Abrasive Grit Cleaning Screen for Remove Carbon, Rust and Scale(12 Pack)

Seems to work very well. A lot better than other things we have tried.

Used this on some hard water stains on porcelain and worked very well

Love used these. Use them in stoves, and glass to clean. Also use on toilets and ceramic tubs and sinks.

LOVE these "scrubbing screens" - they were originally bought because a friend recommended them for scrubbing the hard water stains out of the toilets, which they did do - takes a little patience and elbow grease but it did remove ALL the hard water stain. Now we hit the toilets once a month to keep them looking great. Hubby also discovered that they do a stellar job on our old Weber gas grill grates! They are the heavy round stainless steel grates from our 2009 Weber and these screens managed to get ALL the old baked on grease and black stains off the grates, they look like new! It was a combination of soaking and scrubbing but it did work and now hubby just knocks the new stuff off each time we grill something sticky/greasy and the grates stay as near to perfect as 15 year old grates are gonna get. Just ordered 24 more of these, don't ever want to run out.

Smaller than I thought. Hard to hang on to when scrubbing the toilet. I will get bigger next time. It does work for heavy stains.

This is my "go to" last resort when cleaning shower doors and tile with hard to remove deposits. Works every time. Check to be sure it won't scratch surfaces before use.

Buyer beware scratches cook tops

These are really nice little scrubbers. So far I've only used one and cleaned my bathroom sink, fiberglass shower pan, entire stovetop and hardwater ring out of my toilet. It's now relegated to toilet only, but I think I can get quite a few more uses out of just that one. I gave two of them to my mom and she was also very happy with them.A lot of cleaning power for a very low price.
