I use PBW hot, 140 - 160 degrees for lines and plate chillers that I can recirculate solution. Doesn't seem to work as well at room temperature, and doesn't seem to keep its cleaning ability very long.
I use oxyclean at room temperature to clean everything else. Really does a nice job on glass carboys. Keep a 5 gallon bucket of solution at all times and toss in the dirty equipment to soak. Seems to last longer.
