It's really easy to clear up. Just hot water. A shower head is required, that's about it.
It might take a day of sweating to take away that final 'tackiness' from your skin but only in the way that nearly all wam substances hang around in your pores the day after.
It's a nightmare to get off sinks/taps/bathroom furniture though.
It's worth it though... Genuinely one of the nicest substances to get messy with ever. It's SOOOO sticky and it feels like it increases the grip of your hands so every touch becomes a massage!
I used something similar which I stumbled across in 'Farmfoods' when I was looking for cakes to use in my last session, I can't remember the name but it had the Marshmallow man from Ghostbusters on the tub haha, it was cheap and I think because of the high sugar content ( I assume) it just dissolved when it came to washing it off but Fluff is available quite widely now, just thought I'd let you know of that cheaper alternative
