Hoppes Elite (water based) is probably ok for Triple7 but not #9 which is a oil based solvent. Triple7 should be cleaned with a water based solvent or just some slightly soapy water. Windex with a drop or 2 of liquid soap and some isopropyl alcohol would be at the top of my list for Triple7.

A little 91% rubbing alcohol or ISO-HEET fuel line deicer will greatly speed up evaporation of the water and prevent it from freezing. ISO-HEET is nearly pure isopropyl and easily found at any place that sells automotive stuff. Even Walmart has it. Regular HEET is methanol and should be avoided or at least avoid skin contact as much as possible.
