Never mix bits of leftover hazardous material. Don’t rinse out empty containers.
If almost empty, bring to a HHW collection.
In general, you can place empty HHW product containers, such as quart containers for oil and paint cans, the trash. If no more can be poured or used from the container – it is considered empty and therefore a solid waste.
HHW days are not open to contractors – they are for private use only.
