Shouldn't need to do that. Many people report months of doing no rez cleaning, just adding more pool shock solution while perpetually running clones. I clean my cloner after every batch is rooted. Just fill the cloner with warm water and add regular laundry bleach (sodium hypochlorite) and a few drops of dish soap liquid, I add about a cup to a 5 gallon cloner. Have everything submerged, the pump with spayers, the pucks, etc., and run the pump for about an hour or so. The submerged pump and spayers will clean themselves and circulate the water throughout the cloner and neoprene pucks. Afterward, dump the bleach water and run fresh water into the cloner for about 15 mins, again with everything submerged and the pump running. Lazy man's effective way to completely disinfect and rinse your cloner. You're welcome
