Sell a few bits of junk, a DVD for a buck, kids toys sell, you buy a load of them from someone whos kids no longer plays with them and put them up for 50p/£1. Shove them in a huge bucket and jet wash them if a bit dirty or old. I used to work in a preschool and don't waste money on the expensive cleaners for toys. A bucket or tub with a cup of bleach and water is more than enough to clean germs on any toy. Don't use it on battery toys though, corrodes the parts.
