I have a few of those plastic caddies in the bathroom, the kind that stay up by suction power. Except, just recently, they don't. They keep falling sideways. I took them off the wall to clean them a couple of weeks ago and they just aren't sticking properly now. Are there any tricks to getting these suckers to suck?? I really can't be doing with my bits and bobs all round the side of the bath.
Thanks in advance!
