I used this for the first time over the weekend and was blown away at how good it is.
Now I know that warm water and other cleaning products can be used but I have found them not to be good at getting any other than fresh droppings off.
So on Saturday I noticed mid morning a certain amount of deposit on the roof of the scooby. Out I went to discover it was baked slid and dry in the awesome sun we had over the weekend, good conditions for testing it out.
A quick spray, counted to 5 like the instructions said and a wipe over with a MF and boom gone, and I mean completely no residue at all. So as far as I am concerned this stuff works as well as it smells (peppermint) !
