I have decided that it would be nice to have a solvent parts washer. I'm tired of going through cans of carb cleaner and engine degreaser. Kragen has an OK looking 3.5 gallon unit that goes on sale for $39.00 or so from time to time, but the fine print on the box says it's for water based solvents only. I like the barrel mount ones, and ebay has some good deals, but the shipping always kills the 'deal'. I'm just looking to clean small to medium sized parts, not blocks or heads, the biggest thing might be a junkyard diff. carrier, and of course I'd use it for cleaning my 'utility' and 'project' firearms, SKS and whatnot. I'm also thinking of finding a solvent pump and trying to fab up something of my own. I'm sure I could scrounge up one of those mini-barrels somewhere. I'd like to hear everyone's thoughts on parts washers. What's a good size for a small home shop? Are the ones that use water based cleaners any good for the extreme layers of greasy grime we encounter with used parts?
