Picked up a pre 64 model 94. Not bad shape but action is really dirty. Good news is the bore it bright and shiny, no pitting or any signs of corrosion. I was told the best way to clean is by soaking in Brownell's d'solve. Sounded great until I looked up the price. Just under $50 a gallon (which makes 5 gallons). If I were 30 instead of 68 I could see possibly using it in the future but that is not the case. Is there a cheaper alternative that is equally effective?
