Paint, tar and other adhesives are extremely difficult to remove and may not come off. We will do our best to remove these problem areas as best we can. Cans that have not been washed in several years may also require a few more cleanings before these problem areas are broken up and removed. Please remember… if you have newer cans, they are sure to look brand new after cleaning. If your cans are several years old, they will be clean but may have the “worn look” still present. Please be reasonable. Although we cannot take a can that is 20 years old and make it look brand new, it will be cleaned and deodorized. Bins with unbagged pet waste WILL NOT be cleaned due to contamination of the equipment and health hazard to our employees. We take great pride in offering this new and unique service
