F.B.
I dip into my cupboards for this sort of thing. Something oily, something acid, and something gritty.
avocado and sugar/ salt.
honey lemon and sugar
coffee grounds and olive oil
I haven't had any on hand in a longtime. I used to keep some in a glass jar in the tub. Leaves the tub slick, but hey, its gotta be scrubbed anyway.
Best,
F. B.
