Just reached up to clean dd's velux bedroom window (high so never get too close) and have found that the little butterfly gel shapes we stuck up there a couple of years ago have melted and are now drippy butterfly shapes Has anyone else had this experience? She'd like new ones but I'm not buying more if this is going to happen again...Surely they're designed to cope with the sun shining on them and warming them up through the glass?
TIA
