This is the LC blue grout spomge that Justin from Obsessive Detail carries. The sponge is very thick. Firm, but still soft. Cross cut. Holds a lot of water and suds. I found it easy to clean off the dirt when using the 2BM and rubbing the sponge across the grit-guard in the rinse bucket. It was my 1st time using a sponge of this type, but I liked it very much. I think this is a good sponge, and cleans well around washer nozzles, grills,and the like. I noticed it didn't cause any scratches or micro-marring (easy to notice on black, non-metallic paint). Overall, I am pleased by this tool, and happy to add it to my wash media arsenal. I would highly reccomend it. I took a couple of pics just to give you and idea of the size of it compared to the DD "uber" sponge. ^^^ Like I said, it's thick. Thanks to Justin from Obsessive Detail for the hook-up I hope this review was helpful. Enjoy Roger.
