I just found this one called 'ToyLife All-Purpose Foaming Toy Cleaner' and tried it out on a couple of toys. Smells very fresh and clean, and the foaming action gets it right where it needs to be. Would buy again.
I'm an advocate of mild soap and water. Good for most materials too.
Edit: I amended it from 'all' to 'most'. I should remember to never talk in absolutes, as there's always something I forget. Fleshlights hate soap. For those a spray cleaner is recommended.
