Product Description

Size: 10-Ounce

The Oil That Creeps and Loosens Frozen Metal Parts.

A scientific principle reduces the surface tension so that this amazing solvent creeps into openings as small as one millionth of an inch. Aerokroil is the aerosol version of Kroil that loosens frozen metal joints in minutes. Dissolves gum, dried grease, and oil -- without attacking the metal. Displaces water, provides lubrication and prevents rust.

I have been using kroil at my work (a power plant) for over a year now. This stuff is amazing. At my work, we often have to remove 2" plus bolts that have been rusting in place for the past 30-60 years. Kroil is one of the few things that actually helps. If we still can't get those bolts off with kroil, we usually have to heat the holes up till red hot to get them out. And if that doesn't work, they get cut off. There really is no comparison with kroil and other oils. Kroil leaves no residue that will end up gumming up after a few months like WD-40 does. I started using kroil for household uses, and it does great for tools, windows, and sewing machines as well. Basically, if you have anything mechanical, a can of kroil is one of the best investments you can buy to keep them running optimally. 3-in-1 oil on crack... that's kroil.

If you have a 2004-2007 Ford F-150 or Expedition you know that changing plugs can be expensive!! If you buy this and spray some around the plugs the day before(24hrs),they will come out like a light bulb!!! Throw away the WD 40 and trash the PB Blaster...this is all you'll ever need from now on!!

What are called penetrating oils are used to free up metal parts that are supposed to come apart, but don't, likely because of corrosion and the passage of many years. The standard "penetrating oils" are WD-40 and PB-5. They have worked pretty well for me.

Until I hit the bracket holding a spare tire under a 1984 RV. I used lots of PB-5, and eventually a 3/4 impact wrench. Simply said nothing was working at all. I started to plan cutting the thing out and welding up some sort of replacement. A diesel mechanic friend asked if I had used Kroil. They used it working on large buses, and she mentioned that some airline mechanics swore by the stuff.

I used it, waited a few minutes and gave the bolt another shot. After a minute with the impact wrench the nut began to move slowly! Slowly the movement picked up. The nut actually came leaving the threaded rod pretty clean. Kroil is worth every penny when you have the tough ones to deal with.

NOTE - I don't own any stock nor received any samples. This stuff really works.

I needed to remove the spark plugs from one of my motors. I had heard and read where several other people with the same motor as I have had trouble removing their spark plugs. The spark plugs would break off leaving a part of the plug in the head of the motor. This in turn meant the head had to be removed and taken to a machine shop for a major fix. I let this penetrating oil soak in and around the threads of my spark plugs for a period of time and was able to remove all 8 of them with no problems. Use Kano Aerokroil penetrating oil for those really tuff jobs.

I've been working on my own cars for over 20 years and have used most of the penetrating oils on the market including the so called "freeze-off" products and nothing I've tried works as fast as this. If you leave it on for periods of longer than an hour there's almost nothing this stuff can't get loose. Simply amazing! It's WAY too expensive to be used as a general spray lubricant so I'd recommend it for loosening purposes only.

This stuff is amazing! It is by far the best penetrating oil I've ever used. This stuff has freed up nuts and bolts that have been rusted for years. Highly recommended!

Surpassed my expectations freeing up frozen bolts on an automobile I'm restoring. Tossed my WD-40 in the trash!! Highly recommended if you need bolts loosened especially those that contain rust.

I own a 2005 Chevy Express van with side opening cargo doors as opposed to a sliding door. This is my primary transportation as well as my work van. This particular model van is notorious for the hinges of the side doors seizing due to rust. My hinges were so rusted That I was worried that the stress of opening and closing the doors was going to rip the sheet metal of the body that the hinges are welded to. I tried every off the shelf penetrating type lubricant on the market. Nothing helped. One day, I had to assist an HVAC tech change out a rooftop vent fan motor that was as old as dirt. His company uses this penetrant to facilitate the removal of pulleys and bearings off the motor shafts. I explained the problem I was having with my hinges and he offered me his can to try. OMG! I sprayed the hinges, let it sit for about 5 minutes, started working the doors open and closed, and after about 30 seconds, all of a sudden the rust broke down and the doors started working better and better. I sprayed some more on the hinges, worked the doors, and the rust worked it's way out so that I had black dirty oil dripping from the hinges. I keep this in my van now, and lube the hinges once a month, and work the doors. They still want to rust up and operate hard if I don't follow this schedule. In my mind, if you need a penetrant that works, when all the rest haven't, definitely get a can of this! A little goes a long way. THIS STUFF WORKS!
