Multi-Use Lubricant Squeeze Bottle, 4 Oz

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.

Works as advertised.

The Dupont products are great But the caps are diabolical. Child proof certainly but very frustrating for adults. I have not found a way to make them so they don’t skip trying to open them.

Takes a couple days to notice it working

This stuff is amazing especially on stripped screws or things that have been out in the elements and you want to unscrew it. We had an old metal arbor to take down. The screws were rusted and just in - drop some on and it so helped us to unscrew all the sides. We were able to take it down with ease. Works great on squeaky door hinges too.

I use this for the bunk of a boat trailer. It helps a lot in terms of getting the boat on and off.

On the advice of a friend I ordered Dupont Multi-Use Lubricant for our two car garage door. I applied it to the olnges, slides, rollers and chain. Since then the door has worked noticeably smoother and with less noise. I also applied it to the springs and there has been no rust and no dust buildup after several months. Before getting this product I had been using an aerosol which was labeled exclusively for use on garage doors. It did not work as well as Dupont's Multi-Use right after application and it did not last as long as Dupont's has so far. The only thing I don't like about it is the smell which resembles shoe polish but stronger and lingers for a long time. For that reason I find myself conflicted about using it in the house. UPDATE July/23/2012:-- I find myself using Dupont's Multi Use Lubricant in the garage on many more things than the garage door; Especially garden tools. It sprays on wet and takes a minute or two for the solvent to evaporate. What's left is a soft, waxy film that is drier than liquid oils and attracts no dust! It protects well against rust. I'm sufficiently impressed with the performance of this stuff by now, to change my rating to five stars. I seem to have got used to the smell enough so that it hardly bothers me anymore.

Worked well on stuck wooden window frames. Easy to spray.
