Cheap Tweak?

Guys, seems I have my cleaners(Kontak) mixed up with my cameras(Contax)and I expected you to understand that my wife not letting me buy a bottle of $30 contact cleaner was a joke. Cheap tweeks are one of the best parts of this hobby and I thank all of you with legit suggestions.

I checked out the ingredients in Contax. Heptane(50%), cylclohexane(10%), propane(20%), ethyl alcohol(10%), isopropyl alcohol(10%). Based on this, you can make a cheap, effective substitute using butane and 99% isopropyl alcohol, in a 3:1 or 4:1 ratio. Cost would be less than $2(for a hell of a lot more than you get from Contax), from your local CVS, RiteAid, etc. Also looked into the other two products. Neither of which contains anything most people would easily be able to purchase. However, a can of one of the tv tuner, contact, etc. cleaners that tv repairmen use would be equivalent. I knew they used to be about $12, for a large can. Not sure how much they go for now, but would be a fraction of the cost of Kontac or ProGold.

Osclib: The Kontac was priced $38.00 at a local shop and my wife's comment was "and for what" - no joke. Compared to her Yves Rocher toiletries is seemed to be overpriced. I wonder what it smells like?
