tolulene / chloroform cleaning validation

tolulene / chloroform cleaning validation

(OP)
Good morning, we're processing using toluene, methanol, chloroform and one or two other materials, and are looking to perform a cleaning validation to ensure these chemicals have been rinsed off the equipment as well as residual product. What test methods would be best (outside of visual inspection) to validate and ensure the material has been cleaned?
