All of their products are great, but this cleaner is extraordinary! Cleans well with a fresh, natural scent. Get it when you see it, because it is sometimes difficult to find.

Have been using for a couple years, couldn't purchase in stores, tried several different stores and locations, ordering on-line worked out very well, purchased the largetst size, filled my four bathroom containers. This product is everything it claims to be, and more. I use numerous Boulder cleaning products, all are great, will continue using and order on-line in the future, much easier.

Works so well. I’ve been using the blue goo for years. After one use of this stuff there was so much gunk that came from under the rim, Lol! Smells wonderful.

love all the boulder clean products--and I am from the original organic era in the 60s
