Gallon jug of Famous Fog Machine Cleaning liquid. Engineered to increase the output of heavily used fog machines that have a reduced output due to residue build up in the heat core. This will not usually help a fogger that has no output at all because the cleaning fluid can not travel through the heat core if it is completely clogged. For use in all water base foggers. Run some Famous Cleaner thru your fogger every time you have to refill the tank, use until only steam comes out. Then follow with fog fluid. 9 lbs per gallon.
