Product Description

Loosen frozen metal parts with Kroil Penetrant. When it comes to freeing corroded items in tough spaces, nothing rivals powerful, industry-proven Kroil penetrating oil. Used and trusted by professionals and experienced DIYers alike since 1939, Kroil quickly loosens rusted nuts and bolts, frees frozen shafts, pulleys, and more. No space is too tight to reach, thanks to Kroil’s ability to penetrate into spaces as small as 1 millionth of an inch. Corrosion meets its match, as Kroil dissolves and prevents rust, cleans and lubricates, and displaces moisture. This product can expose you to chemicals including beta-myrcene, which is known to the State of California to cause cancer. For more information, go to www.P65Warnings.ca.gov

    Can't Believe It Took Me So Long!!
    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
