I have never been able to get a Ruger to come out of the tanks looking like the Ruger factory finish. I use the Du-Lite system and they claim that Ruger does too. I had a 1950 Ruger standard that was rusted all over from sitting in a leather holster for 30+ years. so I sent it and a check for 40 bucks to Ruger
and had it back in about a month completely overhauled including the bluing
check a current owners manual or call ruger to see if the pricew is the same35.00 plus 5.00 return shipping. you'll be glad you did
