Thanks, I think I have seen that but stopped reading after the person who had it a week was talking about it, back when I wasn't that interested. Should have made it to the end when long term use was discussed.
Just a recap: the "rocks" can be loose and fall off, though you can rub them off (safety hazard if you dont rub the loose rocks off), hard to clean with traditional methods, although no one had mentioned steaming.
I don't think it would melt or anything if it was steamed. I would assume it would be like a plastic hide. I'd be interested to know if steaming would work for maintenance and not make additional rocks fall off or anything. Or produce fumes possibly.
