Well I do. I have been using a grout sponge from Home Depot but they don't flex or fit into tight areas very well. As it was I had a sponge from Detailers Domain that I had for a while and hadn't been using for a while. Well my last grout sponge went to crap and forgot to pick up another one!! So I remembered I had the DD sponge and it turned out to be the best thing!!! I ripped in half and made it even better. I have ordered another sponge to have on back up for the next go-round
