Mum has a stand alone shower in the corner of her bathroom. Two doors slide aside to allow entry and then you pull them shut behind you to stop the shower from soaking the floor.
Over the weekend she mentioned that the doors seemed to be sticking slightly, and that they would no longer open smoothly.
“Can you do me a favour,” she asked, “and have a look at them for me?”
Not a problem for me, so of course I agreed.
“I think they just need some UB40 or something.” she added, in all seriousness.
