Pinole Cleaners practices the science of green cleaning. This process involves first the distillations tank, which gets rid of 80% of impurities, and then dry cleaning, which provides a second filtration. A strict regimen of non-toxic, non-carcinogenic, non-pollutant solvents is used, which also happens to be biodegradable. This mom-and-pop shop, owned by David and June Choi, also offers fine alterations and heirloom preservation. The couple has been in business for 27 years in Pinole for 10. Items dropped off by 10am can be picked up by 5pm.
