Hi Kathy,
Costco sells a wonderful product called “Oil Eater”. It’s in the
auto section. I’ve been using it for several years as a pre-wash spot
cleaner on washable clothes, salvageable rags, etc. (it helps to
keep Ruth from telling everybody that I’m still a little boy who just
loves playing in the dirt!). It’s very irritating on my skin however,
so I use rubber gloves if I have to touch it. In general, oils and
greases wash out completely. You could also use it on your machinery,
bench top, floor, etc; rinse it up with water very generously and
throw all the rags in the washing machine.
