DuPont Release-It Teflon Penetrant Aerosol, 10 oz

This has a better mix of lubricants and solvents than your typical well known products. I find that it gives me the loosening and long term protection without the film. I’ve used it around the RV, on the bicycle, electric scooter, and just generally everywhere like doors and such. I rarely need to recoat. I have since bought many bottles to replace all my similar products. I’ve also been casually spraying on nuts and bolts to keep corrosion away with perfect success.

I have a spray can of this product and it works great for larger applications but for spot applications it can be sort of a mess because it's hard to not spray a large area. even with the nozzle straw in place. When you need a small amount of the product in a specific spot, this liquid dropper bottle is the way to go. The penetrant itself is a superior product - it works well on rusty fasteners, as a pre-lube for threading nut and bolts and even for cutting fluid with taps and dies. I use this liquid frequently and I highly recommend it for any shop. Hope that helps!

This stuff is like liquid magic Penetrating and Lubricating and lasts!

The product works very well, but as with most similar products, the delivery system (1/16" diameter tube) is difficult to control and the lubricant ends up on everything in the vicinity.

Excellent penetrant, remaining Teflon component keeps parts lubricated long after penetrant has dried. Have used this for a number of years, much better than WD-40.

Doesnt smell bad like the PD blaster that most plumbers use. You can use indoors safely and does the job as well.

Better than PB Blaster BUT the lack of sprayability makes it a choice between the two. Solved the problem by buying both! I have a car from the East Coast and it got some corrosion. This cuts through rust like butta!

Love DuPont, I know my chemicals and I can trust DuPont to never disappoint. Started using instead of PB Blaster, you can watch it dissolving the rust. This is a fantastic product.
