I've heard that you can use a 10% bleach solution to sterilize non-porous toy materials such as silicone, glass, ceramic, and stainless steel. I also know that you can't sterilize porous materials.
Even though it won't sterilize them, could you still use the bleach solution to clean other toy materials like PVC or TPR? Would it break down or harm the toys in any way? Inquiring minds want to know!
