Very easy to use, just pour in head and add water. You need to be diligent about cleaning spills as it does stain if left on light surfaces for more than a few minutes. Very happy with the results. Much cheaper than buying the individual bottles although I must admit that I like the convenience of the individual bottles a little better.

I've used West Marines Exterminodor for a long time. I really like how long it lasts and how well it keeps the smells down.

However, I am treating some sludge buildup in my holding tank with a bacteria/enzyme treatment and I'm wondering if this is compatible. It doesn't say anything about being safe to use with this type of treatment, but it also says it doesn't use a formaldehyde base. A little clarity on this product would be much appreciated!

      Comments about ExterminOdor Tank Treatment:

      Couldn't get rid of the tank smell coming from the vent when we pumped out so we tried this product after cleaning out the tank. It has been controlling the odor so far and we like the mint odor better than the perfume odor normal blue products provide.

            Have tried several different products. This one is the best. Use minimal product with great odor control, even in 90 degree weather. We hold for a week.

                      If you ever have forgotten to add chemical to your head then you know how bad it can smell. This is must have for extended odor and bacteria control.
