Is it cheaper than neat washing up liquid? That's what I've used in
the past for engine oil drips on concrete. Liberal application of
neat washing up liquid, work it in with a scrubbing brush and leave.
Let the rain wash it away. Not "instant" but it works.

I'm not convinced about the biological side of that product. I'd like
to know an awful lot more about the bacteria it contains.

I used a dry powder version of that oil-eating bacteria on mineral oil
stains a few years back and it was amazingly good. Hadn't seen it
offered for a while though.

Agreed, a natural oil like 'teak' should be relatively easily saponified and
will then wash out. Second thoughts, would the carbonate in the concrete
then turn it to scum instead. School chemistry getting rusty!
