Aero Kroil Lubricant, Aerosol Can, 13 Fluid Ounces

I have used this stuff for years. It works well

You get what you pay for. Best overall penetrant. Will save you $$ and headaches when attempting to remove a corroded/rusted bolt or fitting. Simply spray and walk away. Give it time to penetrate. With a little forethought and some patience, your fastener will most-likely break loose. I would't use any other. Always stick with products that are developed and used in the aviation industry. Hope this helps.

I first used this product at my job. We had a giant chiller that had the bolts sheared off on the end cap from pipe knock, so we had to remove the end of those bolts that were still in the metal head. Probably about 4 inches still stuck inside solid metal. At the recommendation of the manufacturer we sprayed this into the remainder of the bolts that were left in the metal, with nothing protruding and let it sit overnight. We went back the next day and tapped those out. There was probably 50 of those inside that solid metal header. Took us about 2 hours to remove all those. A job that would have taken much much longer without this oil. It somehow works itself into that bolt desolving rust and corrosion out of there. These stud bolts probably hadn't been removed in over 20 years. This oil works at home too. It works on old pipes, bolts, etc. We had 2 jet turbine power plants where I worked and we could use it on those. It ends up desolving, not leaving any residue behind. Well worth the price.

I have used Sea Foam for similar purposes but this is in another league. It is the only product I will ever need for its stated purposes. Clean, no overspray, perfect application every time.Outstanding product. This can, tho expensive, will easily outlast 3-4 cans of Sea Foam. A very high quality product.

The media could not be loaded. I have been rebuilding things for years, I have used a few different oils and still have struggle to free rusted nuts and bolts. I have even unsuccessfully tested a few products that I have purchased here. I stumbled on this product and cannot believe the results.The real test came when I was taking apart a 50+ year old spiral staircase, I could not believe the results, I had 13 balusters to remove from the railing. They were covered in in paint and rust. I chipped off the paint, applied a thin coat of this product, waited about 90 seconds and the end result was 100%. I was able to remove 100% of the screws.I have attached a video, if you like my review please press the helpful button, if not ill try better next time.Thanks

I bought this after seeing several recommendations, for helping to remove spark plugs from a Ford, 5.4L 3V engine, which are notorious for binding up and breaking off the tips in the cylinder head, then you're stuck trying to extract them or worse case, pulling the heads off the motor. Per recommended procedure, I sprayed the plugs down, let them set for a couple of hours, broke the plugs loose 1/4 turn, then filled the well up to the top of the hex nut, let that sit over night to allow it to seep past the threads to where the problem lies. I can't tell you how it would have gone if I hadn't used Aero Kroil, but I can say those plugs came out smoothly the next morning, in one piece, with no binding at all! Also used it for cleaning and oiling a couple of guns. Worked great for that! I'm looking forward to testing it out on some really rusted up stuff when I find an opportunity.

I have an old bronco II with a seized engine from sitting for 12 years. Every day I would rock it back and forth in gear to try to unstick it, I pried on the flywheel, tried the crank bolt with a breaker bar, I poured ATF/Acetone, PB Blaster, marvel oil and all sorts of other things down the cylinders to try to free up this engine and nothing was working, it was stuck, solid. Finally ordered this up after reading about it on some forums, and after putting it in the cylinders and letting it soak for 24 hours, the engine started to turn a few degrees. Another soaking and 24 more hours and it broke free easily. I don't know why this works as well as it does, but it does!

I sprayed the rusted nuts on my trailer brakes, let it sit for 6 hours and the nuts were loose.
