I make a solution of 50/50 winshield washer fluid summer blend and 91% isopropyl alcohol. I use it for swabbing at the range because it pulls fowling excellent and drys out of the barrel fast. I also use it when it comes time to clean the rifle. I use the homemade solution to basically clean the rifle to a point where there is no fowling left in it or on it. Then I use a good solvent like Butch's Bore Shine, Birchwood Casey Bore Scrubber, or Rusty Duck Black Off to make sure the job is really done well.

I use this homemade solvenet because it is so inexpensive to make and I see no reason using a solvent that cost $6.00 a pint for a job that a homemade cleaner I make for about $1.00 a pint (if that) will do the same thing.
