I have used breakfree clp for years, including 2 years on outdoor connex containers in wyoming. Never a problem, also used it on
cardboard bailers and forklift. And numerous other power equipment. I have used it on black powder rifles and pistols. It deactivates the acid in the black powder, cleans and lubes is non gumming doesn't freeze even in -40 plus. It's a bit expensive but works so well, and it also is available at most sporting goods stores and Walmart.
Still use this on anything on the homestead that doesn't get grease. The other lube I use but is hard to find is 3 in 1 teflon. I only use this in very specific places it is a dry film lube. Works great on indoor locks and items prone to dust and sand. But must be protected and clean first.
Great thing about breakfree clp is you don't have to even pre-clean. I used it to lube and clean chains, padlocks, hinges, fittings, bicycle, and guns. Freed up a guys ar-15 this winter at the range, wouldn't work at the cold temp. Couple squirts and it was running like a champ. I also use it on all moving surface's on the truck and
tractor. It has breathed new life into old bearings and frozen bearings on hand trucks.
Thanks
