I like the idea
Unfortunately I often have to 'rescue' very large spiders from my sink that have dropped in and cannot climb out. I am not too frightened by spiders yet I still coax them into a glass to retrieve them from the sink. So the thought of cleaning the sink 'blind' and maybe touching one of those large hairy spider legs sends shivers.........
Even worse how about doing a great cleaning job and then opening your eyes to find a wonderfully clean sink........with a couple of small black..what are they..look closer....disembodied spider legs......To find you have enthusiasticaly cleaned a spider to death!
Just a thought
