KROIL 8 Oz. Original Penetrant Oil

Been using this product for years. Could not be more pleased with it’s continuing usefulness.

Tried Kroil a few weeks ago and I was very impressed with how quickly and effectively it penetrated a rusty nut.

The drip can of Kroil combines the efficiency of the aerosol can, and a container that allows the user to apply sparingly. With the drip can, my Kroil can last a long time in the field and at home- never needing more than a few drops and time. Additionally, for users like me who play too rough, the applicator tip is durable and will definitely withstand long drops or being smashed around in a bag of tools. (Oops)

I've used Kroil for over 30 years. I was introduced to it at my work place. Spray it on a rusted fastener and it foams up and seeps right in. This of course was with a spray application, drip works just as well but doesn't foam up. I kind of miss that.

I've been using this for several years. A friend introduced the product to me to help me remove screws from some of the family heirloom firearms that I had inherited. I was amazed at how the product penetrated and loosened the delicate old screws on the firearms. I also have heavy equipment and had a particularly difficult bolt to extract from one of my machines. Instead of pulling out the four foot cheater pipe (my usual method) I soaked it in Kroil over night and was able to extract it without rounding off the bolt or worse, breaking the bolt off in the hole. Now I use it on everything rusted before disassembly. I wonder if it will help lubricate my arthritic joints?

Love Kroil oils. I’m an amateur gunsmith and auto mechanic. Been using Kroil for years I’ve found it’s my go to oil for all my firearms especially old restoration projects

I have a can of liquid Kroil from years ago and it still does the job on my stuck parts!!!

I've been using Kroil for years and won't use anything else. Hasn't failed me yet. Smells great too.

I've been using Kroil penetrating oil for 40 years. I have a can that's so old the propellant has died but it still dribbles out and does the job.

I have worked in Maintenance for over 35 years. I always use Kroil...It works and I even love the smell.

Been using this for years in my job as an industrial electrician. I also use it to clean firearms, and auto repair. It never fails!!!

Loved kroil products for years..been using since the early days.

I use this on my nuts as often as I can. It's the best product to get them off.

Best experience for removal of stuck bolts. Working in the gas turbine busines, we got lots of stuck bolts. Besides that, I like the smell.

I have been using the Kroil the last few years with great success at many bolt and corrosion problems when restoring vehicles has keep me from buying expensive old vintage parts etc,

I have used Kroil for over 25 years because it works. Flat cans with the drip spout, and now I have transitioned to the aerosol can. I don't mean to be derogatory about your product but when I walk into someones shop that uses your product....I can smell it.

I have been in the collectibles business for over 50 years. Among the stuff I deal in are antique toys, many of which are heavily rusted when found. Came across a great looking tin wind-up train from the 1950's whose motor was rusted/frozen solid. Soaked it in Kroil for 2 days, cleaned off the rust, and wound it up. It was so well lubricated (after a shot of Kroil spray) that it didn't want to stop. Just one example of how useful Kroil is to me.

I collect railroad antique articles. Many of these items have been out of service and in "barn storage" for many years. Corrosion does not do good things to stored metal items. I "discovered" Kroil more than 10 years ago and have been using it since. I am currently restoring a street car transit coin box. The Kroil has be great assistance in freeing the many screws and stuck parts for cleaning in the restoration. I have tried other penetrating oil lubricants but Kroil still works the best.

So I'm new to kroil and was put on it by our mechanical shop at work as a "secret recipe" I have used so many different penetrating oil in the past from PB to Amsoil and nothing really caught my attention or my wow factor. This finally did it!! It is a bit pricey but like I have found in the past by cutting things off with a torch or beating the life out of it with a sledge its cheaper to buy the KROIL! I just purchased the small drip can first as a trial but have recently thrown all my other oils to the brother in law, HAHA! This stuff is amazing and I cant have enough of it on my wall!

I was recommend Kroil Oil Penetrant by a gun smith. The best penetrant you can get. Can't be beaten because of it's multiple uses. Not only can it not be beat for loosening rusty bolts but works great for removing built up carbon in my hunting and match rifles. I'll never be at a rifle match and not have a full can with me on my cleaning cradle. I always know once my competitors see how great a job it does cleaning my rifle they are going to want to try it. Next questions from them is where can I buy some. Don't forget for you home mechanics to keep a can handy. It'll surely make your home and auto jobs easier.
