5.0 out of 5 stars Super concentrated and effective – Love it!, August 19, 2010

By kcroswhite (Great Northwest, United States)

We’ve had a jetted tub for two years now. Despite regular cleaning with dishwasher detergent and bleach (as recommended by the service rep for MTI), a few months ago we started noticing gunk showing up in our baths. I purchased a 2oz container of this cleaner a month ago and have used it 5-6 times. The first few times I saw a lot of disgusting looking debris getting cleaned out of the system. The last few times less and less, as the tub is now finally clean again!

Each use, I scoop a bit on the back of my fingernail, and that is enough (anymore and it foams right out of the tub). I would estimate I have used less than 15% of the 2oz. Since I will be using it slightly less often to just maintain cleanliness, I expect this will last at least as long as advertised (probably another 6-8 months). It is in fact a great bargin, in my opinion.

I also appreciate that the manufacturer hasn’t succumbed to bulking it up with fillers just to make it look like your getting more. Small, concentrated products are much better for our environment.
