Scent: Lemon Size: 64 Fl Oz (Pack of 1)
I am giving it 5 stars because I can't imagine it doesn't work as well as Camco black tank treatments. If nothing else, it smells good lol 1) We think Camco makes quality and durable products (overall) 2) We have not had any issues with Camco products 3) Their products are worth the price, which we think is pretty affordable. ... show more
