So, I need to clean down behind a radiator but I don't want to have to get a plumber out to remove the whole thing... and I reckon I can create a sort of long cleaning device with a cloth attached to do the job. However, the gap is relatively small (about 1 - 2cm) so I'd need something quite thin. Any ideas about a long (say 4ft), thin (1cm or less), rigid (so it doesn't bend) pole-type device I could use to create this? I thought like those bamboo canes that everyone USED TO have in their gardens when I was a kid and we of course used as swords but those don't seem to exist any more?? You can get them on Amazon bt it's like £20 for a bundle of loads and I don't want loads! I just want one! Or two... for sword fights after...
