Not something I thought I’d be asking, lol. I left the bath mat hanging over the bath to dry a few weeks ago. It’s the spare bathroom so forgot about it. When I went in today I picked the bath mat up off the bath and it was sticking to it, so I pulled it off, and the underside of the bath mat has stuck to the bath! Little sort of lumps of rubber backing (I assume that’s what it is). Any awesome domestic goddesses have any idea how I get it off please? Without obviously putting a new mat down and never moving it again/shutting the door and never returning/moving house..
