I had someone approach me the other day about cleaning his sealed concrete driveway. My question is, can I use the surface cleaner just like I regularly do or should I treat it like a painted surface and just use a low pressure. (spray on, dwell, rinse off)? Thanks, Erik
 
Maybe..depends on integrity of the seal and/or what type. Solvent type or penetrating type seal is doing to be more able to withstand cleaning forces...
You can make clear to them that if it is actually still sealed then the dirt would not have penetrated in and it might only take low pressure and chem to clean. If the dirt didn't penetrate or low pressure moisture just sits there then it is still sealed and you will not want to harm it with high pressure cleaning without approval and plan to reseal ater cleaning. Determine this as a test process and involve owner. Put it to them and ask how they wish to procede.
