Dear B.,
Many cloth toys can be washed in the washing machine, and there will be instructions on the tag. If not, you can usually put them in a pillowcase or mesh bag and run them through the gentle wash cycle, then air dry in the sun or put them in the dryer on low heat. If the toy doesn't stand up to washing, it probably won't hold up under play.
As for the plastic ones, soap and water will clean and then I would use a non-toxic disenfectant - nothing with cholorine or ammonia - since toys usually go into the child's mouth. You can find these online, Whole Foods and I have found an entire line of products for bath, body and home which are economical, free of toxic chemicals and they work. I love them, and I would be happy to tell you about them.
