    Product Exchange Program: Cleaning, automotive, and garden products can be donated by residents to the ProductExchange Program for other residents to take home and repurpose. This free program is available at all of the county's permanent HHW sites. Quantities and types of materials available vary, and participants will be required to sign a liability waiver and standard release form.
