Cleaning, automotive, and garden products can be donated by residents to the Product Exchange Program for other residents to take home and repurpose.

The Product Exchange Program is available at all of the county's permanent household hazardous waste sites (view locations). Quantities and types of materials available vary, and participants will be required to sign a liability waiver and standard release form.
