Yellow Bike Project in Austin is investigating the purchase of a parts washer. Maybe a 15-20 gal capacity with a pump, and possibly a heater. We currently use donated rags and T-shirts with simple green to hand clean parts and frames. We do not launder the rags,but  just send them to the landfill. We are wondering what is the best solution, ecologically and economically. Advice and recommendations are appreciated. Robert, YB Board Memebr
