What They Said

“Kroil saved the day on a planned 8-hour job of removing cylinder casting studs on the 1309. Having no luck with wrenches alone, we turned to Kroil and were able to remove the studs in just under an hour, significantly speeding repairs on our main attraction.”

“Locomotive 1309 has wear and tear from years of common carrier service on the Chesapeake & Ohio Railroad in the 1950’s. Penephite ensures that the spring-brake rigging and running gear components on this vintage train will last until the end of our careers, and for generations to come.”

“Between both engines – the 1309 and the restoration of 734 – we’re currently using an average of a can of Kroil a day. With multiple projects in our restoration facility going on at once, there’s always a mad scramble to find the bright orange cans.”

“We once couldn’t get a pin out of the horizontal stabilizer of a Falcon 20 business jet. We tried other products and couldn’t get the pin out. We then used Kroil, and within 5 minutes that pin was out. I was sold on Kroil then and there.”

“It’s all about keeping the aircraft operating. Downtime can cost us $1000 an hour, and if we have to fly an aircraft back to the hangar, it doubles that expense. If we didn’t have Kroil, it would be hard to do our job. Kroil is a real time and money saver.”

“When soaking parts in Kroil, the parts will come out. Even if a part is so far gone that it no longer works, at least you can get it out and not have to destroy surrounding parts. It’s an excellent penetrant, and I always keep some in my toolbox.”

“We like using Kroil, because when you spray it on, you can actually see it working into the threads. It’s just a great product.”

“Replacing front-end steering components is a very expensive and time-consuming repair. If you don’t use Kroil, a repair that usually takes 4-5 hours to complete, can easily balloon to 8-12 hours or even a 2nd day of work.”

“We come across a lot of rusted, older and specialty bolts. If we can’t get them off, we usually end up breaking them, which causes a lot of problems. And, if we don’t have the bolts on hand, we have to order things and the car sits longer, tying up the shop. So, we use Kroil to soak the bolts and crack them loose. This saves a lot of time, especially for some of the older stuff.”

“We’ve found Kroil to be the most effective. If you use a good penetrating oil, 
such as Kroil, it actually penetrates itself into the middle of the nut, and lubricates the thread, which makes it a lot easier to take out.”

“Kroil is our go-to penetrant. It definitely helps make our jobs go smoother.”

“If we have to go and replace a piece of equipment that has been sitting out in the environment for years, chances are there is going to be a lot of rust and corrosion on anchoring bolts, valves, etc. Kroil really helps with the 
process and allows us to complete the job.”

“I can tell you one thing, Kroil, that’s a staple. Make sure you’ve got that in your truck. You go to 90% of these WAM vehicles, and you’re gonna see Kroil in there. Guaranteed.”

“We always have Kroil in our toolbox, because we know it is the only thing that will help us get the job done. We believe in the product.”

“I’ve been doing this since 1978, and know what works. I have never found a product that can equal Kroil.”

“We use Kroil to break loose bolts for railings and seats that need to be replaced as well as on stuck concession roll-up doors. We use it because it works.”

“I use Kroil every day to service our rooftop units and air handlers. We would have never gotten the fan blades off a few units without Kroil.”

“I spray every window glide for my suites with Aerokroil before every event. It breaks free even the most stubborn and tight ones. I easily use a case of Kroil for my floor of suites for each event.”

“We deal with a lot of rusty stuff, and Kroil works better than other products for rusted metal and bolt removals.”

“We wouldn’t be purchasing Kroil if our team wasn’t asking for it by name. It’s a really good product.”

“Any time we need to get something rusty apart, we take a can of Kroil with us. There’s always a supply of it in our tool crib. Our local machine shops also use it.”

“When techs ask for specific products, like Super Lube grease, I order it. These guys are very brand loyal. When they ask for brands, they have a reason behind it. They know the quality of the product.”

“You can buy one can of Kroil or you can buy three cans of a competitor. There’s a reason why it works so well. Don’t give me the cheaper stuff. Don’t change it.”

“We use many different products, and our techs ask for Kroil because it works. It’s more expensive, but it works better and saves us hundreds of dollars on the backend. These guys have been doing this for 20-30yrs, and there’s a reason why they choose Kroil.”

“It does the job so well; it pays for itself.”

“My go-to is Kroil Original Aerosol. As far as penetrant goes, it is unmatched.”

“Like magic, the lubrication penetrates the toughest bolts.”

“Kroil reduces our labor man-hours by 30% on a daily basis. Some other products just don’t cut it. Kroil helps us save time, which in turn, saves the owner money by reducing their labor bill.”

“Union Ironworker. We use it all the time!”

“Working on cars with my dad, and after the first broken bolt he told me about Kroil. Better late than never.”

“$50,000 worth of monotype equipment lay idle while we messed with twelve lousy screws. Soaked the parts in kerosene, light oil and several other penetrating oils. Then, we used Kroil, which turned the rust to mush, so we could turn the screws and use the machine again.”

“I freed a stuck brake wheel cylinder piston with Kroil Penetrant with Silicone. Just minutes after spraying it on top of the piston, it was able to be drawn out with no damage to the piston.”

“When I worked for Boeing  it was the only penetrating oil allowed on our production floor. Never seen anything like it.”

“Became a true believer of the Kroil products today. We were trying to pull a fan drive off the front of an engine and it was just not working. Had a cross bar puller on it and had it tensioned up pretty tight. I walked by the service truck and saw that Kroil can, so I sprayed a little bit on the back of the shaft and it popped about 3 seconds later! Started back with the puller and it fell off in my hands!”

“When I joined the Rolls Royce Owners Club almost 30 years ago  members strongly recommended Kroil products. I tried and have used regularly ever since.”

“I don’t really care how much the stuff costs…a couple of squirts of Kroil just doesn’t cost that much compared to the cost of the job.”

“Kroil has been the most impressive penetrating oil…I would never not have Kroil on hand for the toughest jobs.”

“Kroil is the penetrating oil that I swear by. If you use it on a seized part, it is guaranteed to come apart.”

“I was 5 years old and my Grampa was working on Grams car. She had a flat tire and was stuck in traffic in Boston on a one way street. I remember it was after school and there was a lot of traffic and people were getting angry there was a lot of yelling and shouting. It was very scary and my Grams started to cry. Gramps came and started to change the tire. It started to rain and I could see him getting frustrated. He went back to the trunk because the lug nut wouldn’t come off. He had this orange can and sprayed it on the frozen lug nut. Honestly it broke the rust free. He changed the tire and Gramma left and traffic started to move. As I have grown older and learned it was KROIL, I never bought another product. I tell my friends and family even coworkers about how well it works! Great stuff would highly recommend it.”

“One time and I was a believer. My tractor had been sitting a very long time and I had to break the tire loose. Sprayed with Kroil and let it sit overnight and WOW!!”

“Kroil does the job so well. It pays for itself by working easily and quickly.”

“A machine shop foreman swore by it and introduced me to it almost 30 years ago. It worked better than anything else on rusted stuff.”

“Had a bolt stuck on an outboard motor that had years of heavy use in saltwater. After throwing every other penetrating oil on it (and failing), I found Kroil. Literally one application and the bolt was out!”

“We deal with a lot of situations where heat has frozen all bolts, particularly on hot box core jobs and heat treat ovens. Before Kroil, it was burn ‘em off and drill ‘em out. Now, we have a high rate of success with just Kroil and a hand impact wrench.”

“I was an apprentice in 1973, and the maintenance men used Kroil to loosen upside rusted gib bolts. Made me a quick believer!”

“Rusted motorcycle axle. I beat and heated it  nothing. Put some Kroil on it over night and 1 whack it came loose.”

“Prior to using Kroil, we had to do a lot more manual labor to free frozen parts. The breakage rate was 85%, which then required drilling out the broken studs. Kroil has reduce stud breakage by 80%.”

“My Father was a machinist and used Aerokroil. So when I started in the HVAC trade and needed penetrant I reached for Kroil!”

“If I see a can of Kroil in a shop, I know they know what they’re doing.”

“A friend gave me a can  best stuff I’ve ever used. Stuck bolts give me no fear because I know Kroil will unstick it”

“My priest suggested Kroil to help me clean up my language.”

“I was given an old can of Silikroil years ago from a tech who was liquidating an electronics fabrication company. I never heard of the stuff before. I noticed it had a faint sweet odor- unlike another penetrant that I loath using because it stinks so bad. I first tried it on some frozen lug nuts on my van that I suspected had galled because I couldn’t budge them even with a breaking bar. Silikroil did the trick! I was amazed! I have been hooked ever since and always have some with me at every job. I think of it as 10-50ftlbs of torque in a bottle and has enabled me to work on repairs that normally would have required air tools. Now I use it to restore old Hammond organs with frozen or jammed parts as it is safe for delicate mechanisms and has saved me from having to do involved and time consuming teardowns to unfreeze hard to get at gears.”

“I first used Kroil at the nuclear plant I worked at  it, worked very well, so I started ordering my own for on the farm.”

“Restoring my 1974 Lotus Europa Twin Cam Special, Kroil let me remove the 50 year old bolts and nuts without breaking a single one.”

“I read about the best penetrating oil in the world and had to try it  about fifteen years ago. At that time it was called Aero-Kroil.”

“I worked for the federal government and I was trying to get a penetrating oil from the supply system. This was back when we used cards and microfiche to try to find what you need. Out of several attempts to find a good stock number for something that worked, I was buying Liquid Wrench out of my own pocket just trying to get the job done on stainless steel bolts in aluminum structures on the ocean. Then the FSN gods smiled upon me and I got a can of Kroil, only they called it AeroKroil back then. Oh what a change! I was getting so tired of drilling out broken bolts and re-tapping the threads. I ordered a case and passed it out like candy. I no longer ended up looking like the tin woodsman from all the Anti-seize compound. It took me awhile to find a local supplier so I could have some at home too. Now I am retired but still hooked up with Kroil.”

“I used Kroil as a mechanic at the power plant that I worked in for 32 and 1/2 years. Used it numerous  times to free rusted nuts and lubricate parts.”
