This depends on the toy that you choose. Remote control excavators probably need the most care, since they have electric parts. Most likely, this will involve wiping them down and/or spot cleaning them. The plastic trucks and toys are much easier, as you can hose them down or dunk them under water to wash them. Some, like the Green Toys digger, can go in the dishwasher. Follow the manufacturer’s recommended care instructions for the best results.
