How to prep solid plastic toys for donation
Toss solid plastic toys in a sinkful of hot water and add a splash of natural dish soap, and wash them by hand.
You can also plop them into a mesh bag on the top rack of the dishwasher for a good, sanitizing clean.
Otherwise, scrub them down thoroughly with natural disinfecting wipes or a microfiber cloth dipped in a solution of 1:1 cleaning vinegar or white distilled vinegar and water. (Why microfiber?)
