When I purchased this I didn't realize there were two different formulas. I have been using the natural for years and been very happy with it. When I started using this formulation it would just run off an apple leaving very little to rub with. It is very watery and did not remove the wax. Then I realized my mistake. I am going back to the natural and dumping the organic.

Ex Output:

negative
