Review on Tinfomyou Cleaning Sponge Bathtub Kitchen by Renee Robinson

So far I've used 2 brushes out of 3, the big flat round one and the one that looks like a toilet brush. The large round one I used for my textured bottom plastic tub. Even with a grocery store dishwashing brush, I couldn't completely clean the bottom of my tub. (Note: I have four boys who like to play in the mud). The large round flat brush worked well, but when I tried using it at an angle or in small areas, the black plastic on the brush would rub against the tub and create a large black streak. So I would recommend only using this brush on absolutely flat surfaces. I also used a toilet brush in my china sink with a bartender friend cleaner. It worked, but I did notice that the brush took longer to remove the stains than using the scrubbing side of the sponge with bartender's friend and elbow grease. I think I'll stick with a sponge on this one to save time cleaning the sink. I recorded the results before and after the sink cleaning. For the top edges of the sink I used a regular dish brush and for the bottom of the sink I used a toilet brush with a drill bit. I used a consumer grade Dewalt drill bit for reference.
