It is Kroil. It loosens stuck screws and smells like only Kroil does.

GReat stuff.
Creedmoor sells this cheaper than you’ll find it most anywhere!
Krill has always been known to be an excellent penetrant and works well to get into small spaces and loosen rust. The same can be said to help remove rust from both inside and outside rifle barrels along with 0000 steel wool.
Great for bore cleaning (mixed) and as a penetrant. The non aerosol application is great. No slopping oil on everything you don't want lubed.
Exceptional cleaning of my rifle bore. I run two wet patches through the bore after a match and that has helped maintain accuracy and barrel life IMO.
I have always had difficulty getting Kroil oil. The only business in my area thatI can it is in Spray cans and gallon containers.I was thrilled to find it here. This is the best penetrating fluid I have ever used, and I’m old. For anyone shooting, it is a must.
works great. Can`t believe I hadn`t tried it sooner.

Having worked with my hands my whole life; this is the Best Rust killer I've used. If It's stuck, just shoot it with this. It also cleans out cables on motorcycles. Better than what some use WD40.kroil DOESN'T COLLECT DUST.;IT EATS RUST.
