What is it and what's the USP? It's a small sponge all the way from across the pond especially designed to rub away all those fake tans mishaps. Used wet it'll slowly rub away all evidence that your tan was acquired in the bathroom and not on the beach. So whether it's stained palms, streaks, buildup around knees, ankles or toes or just that the colour is too dark you'll be able to gently rub it away.(£10 for a pack of two, thisisbeautymart.com)
How new is it? It's been available in the UK since last year.
I’d try... Using it dry to get rid of deodorant stains from clothes, I reckon it would do a great job...
