Nature's Secret Weapon Ultra Concentrate Instant Odor Remover has been reformulated to work even better than before.

Please note the following changes to the instructions on our bottles:

Spot Treatment: 1:2 solution (1 part Ultra Concentrate to 2 parts water)
Use of 1:1 solutions and straight Ultra Concentrate is no longer recommended.

Shelf Life: Ultra Concentrate has a 2 year shelf life. 1:2 solutions have a 7 day shelf life. All other solutions (1:3 - 1:9) should be used the same day they are mixed.
