Where can I find a toy sterilizer in Manila? Online shops may do.

I think ordinary bottle sterilizers may do. But just remember to never clean battery-operated toys using it. In cleaning toys, I just toss them inside the sterilizer, especially the ones made in plastic and silicone. Plush toys go to the laundry.

You can check Aller Plasma Toy Sterilizer on Facebook. Not really sure how much one costs as they give the price privately. They have their details posted in their page anyway if you have questions.

In lieu of toy and bottle sterilizers, you may want to also try using baking soda and vinegar. They're effective in swipping off bacteria and 100% natural too
