What I am about to post many people will be using already but I have just "discovered" them as I am always the last to know.
When I was working I never knew anyone was pregnant till they were in the last throes of labour.
Anyway I have discovered Flash Anti Bacterial wipes are very useful for wiping lockers out,wiping the floor and many other applications ( inc. little accidents around the toilet when the grand kids are there).
The best place to get them from is the pound shop where you will be amazed to discover they are only a pound.
Disclaimer :- Other brands of wipes are of course available and from other outlets.
