Seems to work really good for cleaning flat top grills at the bar I cook at very impressed on how well it worked!

I'm relatively new to pumice-based grill cleaning. I bought these as a replacement to my original set of two pumice stones (which I sadly can't find anymore), which I loved—I'm a pumice convert for life from using them—but of course they eventually run out. With this purchase my thinking was, "If these are so much bigger, imagine how long they'll last!" That thinking didn't hold up at all in practice.To compare these side by side, the rough dimensions of each of these stones is 8" x 3.75" x 3.75". The pumice stones I was replacing were roughly 4" x 3" x 3"—less than half the size. I had used my previous (final) pumice stone a dozen times to do the nominal post-cook grate cleaning of my three grates, which had used up roughly 1/3 of the stone. This left me with 2/3 of the stone going into a deeper, top-to-bottom cleaning of the grates. I was able to do a thorough cleaning of 2 of the 3 grates with that remaining 2/3 of a stone. Then I broke into these replacement stones. Here's what I observed.- I exhausted a single stone before even finishing the final grate.- It did a *terrible* job for what it did "clean"—I couldn't fully remove a remaining black residue on the grate without busting out a sponge scrubber, hot water and soap.- Unlike my previous stones that left a powdery pumice residue to gently wipe off the grates, these brittle bricks flaked off large chunks like carbon shards, all over the place, making a messy clean-up after the fact.- This is the deal breaker: these stones off-gas with a smell like sulphur when you use them. Like, bad. Thankfully I was cleaning the grates outside, and outside of the grill.Needless to say, I didn't bother to open another stone to finish the job. They went straight into the trash.I wish I could get ahold of the previous stones I had. But I'll test drive some other ones in the meantime, because I can't imagine that I'll encounter a replacement that's worse than these are.

It scratched my flat grill to hell and back, you say it won’t but boy it does bad
