This is the Penetration Oil that I use. A number of years ago, the tools in my toolbox were going slightly rusty, so I sprayed them with WD40, and they got worse. It would have been better that I did not spray them. Then I heard of INOX, which is actually Oil Based and it works a treat. This is how their blurb describes this product:-
The only lubricant in the world with the special MX3 anti-corrosion, anti-moisture formula for the twenty – first century. MX3 is an anti-corrosion anti-moisture lubricant designed to be sprayed on surfaces and between moving parts. The lubricant is made with a high grade white oil, rust inhibitors and other components to give lasting protection from corrosion and oxidation. MX3 will penetrate through bolts and parts that are stuck together to help loosen and easily free up without causing damage.
Over the years INOX MX3 has become known as the “Supreme Lubricant” and the go to product when the highest of quality is needed. The special MX3 formula is now sought after all around the globe making it one of the leading lubricants in the world today. These qualities make it safe for almost every market out there including: Automotive, aviation, commercial, domestic, electrical & electronics, engineering, farming & mining, firearms, fishing, hobbies, manufacturing, marine, motorcycles, sports and transport.
