Kroil Original Penetrating Oil (Drip-8oz Can-Case of 4), Penetrant for Rusted Bolts, Metal, Hinges, Chains, Moving Parts, Rust, Corrosion Inhibitor (AZKL081C4)

Back in the 1960's when I was a kid, my Dad would hire me to shovel metal chips out of his cutting machines. Dad had a small machine shop that employed two and sometimes three people. I would shovel chips out of each machine and then oil the machines with different lubricants. That was my job for a couple of days after school. I learned a lot about maintenance of machine tools. One day, I bought an old three speed bicycle so I could get back and forth from school to job. It was old, rusted, and needed some TLC. I needed to change the tires and tubes so I did, after I got done with my job at the shop, but could not get the wheel off the bicycle frame because of rust on the axle bolts and nuts. My Dad was an avid Kroil user and taught me how to use this penetrant. My Dad always bought the gallon cans and filled an old Eagle metal pump oiler that had Kroil printed on the can. He told me to squirt a little of this oiled on the threads and wait a couple of minutes so that the oil could creep into those thread and and break-up the corrosion between the nuts and threads. WOW, it worked! All four axle nuts came off so easy. When I took over the family business in 1982, I made sure we always had the Original Kroil in stock. But then I discovered aerosol SiliKroil and that became a standard in the shop too. It works just as well as the original Kroil but has so many more applications. We machine a lot of aluminum and when we don't use a coolant, we use SiliKroil as a cutting oil on the dry lathe. It works so much better than Kerosene and smells a whole lot better. All the other machines use a water base coolant. If I'm hand drilling a piece of metal, I always lube it up with SiliKroil because it cuts down on the drill wear and the drill won't grab as you drill through the metal piece. We are still using the same old push lawn mower Dad purchased back in the early 1960's to mow the shop lawn. But I noticed one day it was getting hard to pull and excessive black smoke was coming out of the little muffler exhaust. I thought there goes the piston rings. I was placing a shop order through my supplier and noticed Kreen was a gas treatment, so I ordered a gallon. Mixed it in with the gasoline and over a couple of weeks I noticed that it was easier to pull start and very little black exhaust coming out of the muffler. Again, I was impressed! You got to love those Briggs and Stratton engines! I've been an avid fan of Kroil products since 1965 and will continue to use Kroil products as long as I am still the shop owner. And by the way, I'm still using that Eagle pump oiler with the original Kroil penetrant in it!
