Hi folks, I am converting an acid washer I bought at work to a parts washer. I will post some pictures later but it is probably 2.5ft deep, 2.5 feet wide, 4 ft long, made of 304 stainless and has 3 120 volt heaters on the bottom. What I am looking for is a solution I come put in there that is not flammable and will not freeze. I know the freezing part is going to be the hard part. Also if you guys have seen any kits that include the pump and cleaner hose that would be great.
