I've had a 3 gallon plastic bucket with a lid holding my Ed's Red for years. I get a lot of WWII bring back pistols with old grease and oil in them from 60 years ago. I night or two soaking in Ed's and it cleans up in jiffy. Got to be careful as it will remove painted safety dots such as are on Walther pistols.
Make you own. It's cheaper and last years.
