In Dublin, you can return up to five gallons of used paint to Sherwin-Williams Paint store at 6309 Dougherty Road. The paint must be part of the PaintCare program and must have a valid label on the paint can. Visit the PaintCare website for detailed information on how to recycle your paint cans. We suggest that you also call Sherwin-Williams at 925-551-8355 if you have a question about what they will accept. The Alameda County HHW facilities will also accept paint.
