found a good degreaser

[Livolsi, Stephane]

It's called Chomp! Environmentally safe and non-toxic.  Ingredients list
includes non-pathogenic single cell organisms....WTF?  Claims it works
naturally by using enzymes to break down the grease, oil, etc.

I found it worked quite well, very immediate on light spots, but you have to
let it sit on heavier stuff, it eventually breaks it down quite well and
just wipes away.

I got it at Canadian Tire
