The foaming is great because it keeps the Remedy in one place as a foam, a cloud of the water-based product. Spraying on the watery product allows it to run and not just sit on the dirt/residue/oil and work its magic. It is an excellent adaptation. If you use Remedy, use it as a foam.

This morning I used it on a bet mark and was amazed at the ease with which it ate through it, after sitting there for, maybe, 15 seconds, if that long. I wasn't able to do that with the water based product.
