I just recently purchased this product for the first time, I have used a couple of times and feel comfortable in giving it high rating. It has a pleasant smell, cleans well and leaves no residue on fixtures.

I purchased this product to try as I like many other BioKleen products. Particularly the boat detailing products. Our bathroom tub was pretty bad with grime, mineral stains, soap scum, etc. After two applications, a little scrubbing, and a hot water rinse, the tub is night and day and took less than 10 minutes.
