Dupont Multi-Use Lubricant Aerosol Spray, 11 Oz.

Purchased to keep my lawn mower deck from getting clogged while cutting overgrown, wet grass. Changed the blades, cleaned under the deck and applied the lubricant. Worked like a charm!

I was confused by all the different non-oil lubricating sprays available, so I purchased a variety and tested them out to compare them against one another. I found that they all have different properties and are best suited for different applications. My testing was simple. I sprayed all the lubricants for an equal amount of time over an equal area of aluminum foil. I then monitored them all over a period of a week indoors at an ambient temperature of around 20C. Then I applied 100 grams of force to each test area and subjectively assessed the amount of reduced friction. (see photos) DuPont Silicone Surface Safe Lubricant. This contains silicone, Teflon, and ceramic boron. It remained fully liquid, thin, and runny even after a week. This seems ideal in situation where you have parts that require a liquid lubricant such as bearings, etc. Best to use this in situations where you would usually use oil, but when you cannot use oil-based products. DuPont Chain-Saver Dry Lubricant. This is a molybdenum and Teflon wax-based lubricant. This remained fully liquid, very thick and waxy after a week. This is formulated for bike chains, and I can see why. Ideal for mechanical parts that must engage and disengage repetitively. Another possible use might be for zippers or similar fasteners. DuPont Multi-Use High-Performance Lubricant. This contains Teflon and silicone. This is essentially a compromise between all the other lubricant sprays. It stays liquid and wet after a week, but is not a lubricating as the others, not as non-stick as the others, and not as friction-reducing as the others. If you can only have one bottle of non-oil lubricant spray, this is a good choice, but it is not the best at any one thing. Basically, like the WD-40 of silicone sprays. Super Lube 91110 Silicone Spray. After a week, leaves a very thin, nearly dry surface, incredibly slippery with the best friction-reducing properties of all the sprays I tried. Wonderful! Also, this is H1 food grade safe (ok for use in equipment used in contact with food). If you need to reduce friction on long rail and track mechanisms with minimal tackiness that might attract dust, this seems ideal! Super Lube 11016 Dri-Film Lubricant. After a week, leaves a dry surface, rather slippery in reducing friction and rather non-stick. This is also H1 food grade safe (ok for use in equipment used in contact with food). If you must have a fully dry film lubricant, this is my favorite! DuPont Non-Stick Dry-Film Lubricant. After a week, leaves a dry opaque white film. Not really slippery or lubricating against friction, but entirely non-stick. Essentially like Teflon PTFE in a can. In situations where you want a non-stick coating like PTFE, but using Teflon tape, etc. is not an option, this seems like an excellent choice.

This was very easy to use in lubricating the slide out mechanisms on our 5th wheel camper. An RV repairman told us to use a Teflon product on the slide out gears and slide teeth as well as the upper side of the slide arm. I first used a stiff brush to remove the debris off the teeth, gears and top of the slide arm and then sprayed the teeth on the slide while holding a piece of cardboard above the slide mechanism. (I did this so I would not get any overspray of the lubricant on underside of the slide. It could drip onto the camper floor when closed otherwise). I then sprayed it on the top of the slide arm. There was a noticeable difference in the sound when closing the slides. I just did this before we winterized and garaged it for the season so I cannot speak to how long the lubrication lasts. I will find out in the spring. :-)

Dupont Multi Use Lubricant is reasonably high performance

excellent

Perfect lubricant for garage door tracks. If you're tired of your noisy garage door by this stuff it works.

I have been buying this product for 15 years to lube my bike chains and I also use it on sticky sliding windows, etc. I usually only buy the liquid version that you drip out of the bottle and that's probably the only one I'll buy from now on. The problems I've had with the spray is that the red, plastic nozzle extender doesn't even fit and the regular nozzle comes off frequently. Stick with the regular liquid bottle would be my suggestion (5 stars for that product).

Best lubricant ever! Does not attract dirt and works great in hot climates.
