“What is the best cleaning procedure for contaminated oil drums? We are starting a project for off-line purification of 80,000 liters of varnish-contaminated turbine oil. The oils arrive at our workplace in 55-gallon steel drums. The challenge is washing and cleaning dirty drums and filling them again with purified oil. Is there any standard procedure for cleaning tight-head drums, or should we dispose and replace them with new ones?”
