In another thread, PeteH from Tarrytown New York made mention of Aero-Kroil from Kano Labs. He indicated that he thought it was the best penetrating oil ever, and in some ways I agree, it is great stuff. Kano bills it as the "oil that creeps" and it does have a way of getting into places that other oils just don't seem to succeed with. Anyway, Pete wanted to know if anyone knew of anything that worked better, so I thought I should mention it in a separate thread.

Keep in mind that what follows are my opinions based on my experiences, I have no connection with either manufacturer, nor with any retailers.

I don't necessarily think that there is anything better than Kroil, but I do believe that there is an equal out there, called K&W Knocker Loose. I first found this brand at a NAPA parts store 20 years ago or so, and it was recommended to me by someone else.

I have found that there are cases where one product excels above the other, as follows:

Where heavy rust and corrosion are the only concerns, I usually use Kroil, and I allow it to soak as long as possible.

In cases where rust is not so heavy, or where old caked grease is an issue, or maybe some light lubrication is required, I use Knocker Loose. It is cheaper than Kroil and much easier to obtain. Works a bunch better than WD-40 or Liquid Wrench.

Just my $.02 Hope that someone else might find it useful.

WD40 has little value as a penetrating oil, protectant, or a rust release agent. However, it does work well at what it was designed for, water displacement, hence the WD in the name. It's also great for cleaning greasy and oily surfaces and for removing the tacky remains from sticky lables.

I remember reading a test on products like Kroil, PB Blaster etc., and the best value which was equal in effectiveness to the best of the rest was a 50/50 mix of acetone and ATF.
Obviously it doesn't have the same convenient delivery system as an aerosol, but I've found it to be very effective in breaking free seized and rusted parts. Just like the others, it needs to soak in, and don't use nail varnish remover in lieu of neat acetone as the nv remover contains water.

Mac hit the nail on the head, ATF and acetone or naptha and douse on liberally. Otherwise I am a strong supporter of PB Blaster as a close second. The ATF concotion works great and has plenty of solvents to help clean sludge and gunk build up if used fathfully. Just remember it will burn if you get it hot enough or expose it to open flame or heavy sparkes. So remember shop safety and exercise caution always.

I first saw Kroil used a few years ago when a friend used it on his auto brake repair job. He lived in the east where a lot of road salt is used and the bottom side of the cars are held together with rust. It is the best rust penetrant I have used and I now keep it on hand by the gallon. Getting it for me is not hard as the company is local and I can drop by when in the city and pick up a gallon. I
have heard about K&W Knocker Loose but have not used it. Sounds like I should.

I know what you mean about the cleaning action of other oils/penetrants. I have used WD-40 for cleaning and removing labels forever but have recently changed to a cheaper mixture of 50/50 ATF and kerosene. The kerosene is a good thin solvent and the ATF adds a little lubricant and rust protection. I keep it in an old recycled plastic spray bottle so it is easy to use. It sprays almost as good as the aerosol cans.

Darn it, now I have to go find some K&W Knocker Loose to try.

When I was in the Navy and aboard the USS America, the guys would come up to medical and get me to get them some Evergreen out of the pharmacy, they used it to break loose rusted bolts and studs on the planes. That with a needle would get the job done.

As for Kroil, I use it alot when it comes to cleaning my rifle barrels.

I have used Kroil Products for over 25 years and I have never found their equal. I buy regular Kroil in a gallon can and use it with a pressurized sprayer. I have two examples that make my point. I was once disassembling a rollform machine that had been stored outdoors for years. There were about 16 shafts five feet long by 4" diameter that had various tight fitting rollers and spacers that had rusted in place. We tried setting the shafts on end and poured Liquid Wrench on and left them over the weekend. Come Monday morning most of the rolls wouldn't budge and the ones that moved needed a lot of persausion. We cleaned up the mess and got a gallon of Kroil shipped overnight. It got there the next morning right before our break. We doused them the same as with the Liquid Wrench and took our break. We came back 15 minutes later and I banged the roller on one of the shafts with a hammer and the whole stack of them fell to the floor, I was lucky I didn't break a foot! The other case was a toolmaker's clamp of my dad's that had rusted up when our garage roof leaked when I was about 8. Over the years I had tried various products without success. I was about 40 when I used Kroil on it and it freed up. (You can tell how hard it is for me to throw things out by how long I hung onto a piece of junk.) I've giving samples of Kroil to buddies of mine who restore old bikes and cars and I've never heard anyone complain about it not working. I don't work for Kano Labs but if I had to make a living selling stuff this would be the product I'd want to handle.
 
Agree the Kroil is the best 'creeping' oil I've ever used. Doesn't exactly smell like a bed of roses, but boy does it work.
 
I agree with others. Kroil and pb blaster both work good. The key is to let them soak and do their job. Soak and just walk away.
