Bring batteries to the Wastemobile too!

Get rid of old car batteries, oil, solvents and other household hazardous waste through a program that is available to all King County residents, at no charge.

The Local Hazardous Waste Management Program in King County provides a year-round Wastemobile hazardous waste service at The Outlet Collection (formerly the Auburn SuperMall), at  1101 Outlet Collection Dr. SW, near Sports Authority. It operates every Saturday and Sunday from 10 a.m. to 5 p.m.

The Auburn Wastemobile location offers the same outstanding service as the roving Wastemobile that travels to cities throughout King County from spring through fall.

Like the roving Wastemobile, the Auburn service accepts a wide range of household hazardous waste, including oil-based paint, household cleaners, propane tanks and other chemicals.

By properly disposing of these wastes and keeping them out of the trash, sewers and storm drains, King County residents are helping safeguard the environment and reducing hazardous materials in their homes.

King County businesses with small amounts of hazardous waste can also visit the Wastemobile service up to four times a year. This program is not for businesses that: regularly generate hazardous waste; have regular pick-ups by a contracted vendor; or generate extremely hazardous waste. More information is available by calling the Businesses Waste Line, 206-263-8899, or via email,

Looking for reusable household products? The Wastemobile provides free products to the public, such as oil-based paint, stain and primer, plus wood care and cleaning products. Items are subject to availability, and residents must sign a release form prior to receiving the materials.

For more information about safe disposal of household hazardous products, including acceptable materials and quantity limits, visit, or call the Local Hazardous Waste Management Program’s Household Hazards Line at 206-296-4692 or 1-888-TOXIC ED (869-4233); TTY relay: 711, Monday through Friday between 9 a.m. and 4:30 p.m., except holidays.

The Wastemobile has been traveling King County for 25 years and is one of the services provided by the Local Hazardous Waste Management Program through a partnership of more than 40 city, county and tribal governments working together in King County to reduce threats posed from hazardous materials and wastes.
