How can you safely and effectively surface clean baby toys without ruining them?

My son has toys that crinkle, chime, play cute little tunes, rattle, have all sorts of different kinds of textures, etc. that I really do not want to ruin for him. I was thinking of maybe just wiping them off with a washcloth soaked in a solution of baby wash and warm water, then line dry them. Is that the general idea of what they mean by surface wash only with mild soap and damp sponge and lay out to dry? Any better ideas on how to clean these things? Just stick to it? What do I do?? I sure would appreciate some advice!! Thank you!
