In the old days before teflon we used to use axle grease between the leaves or just put them back together with nothing between the leaves. The grease will help some but not nearly as much as teflon strips and it eventually dries out. I'd go with the teflon strips. Is there some reason you want another alternative?

As GNW said the old school method was to cut strips of nylon window screening and slather them with wheel bearing grease, then wrap the whole spring in rubber electrical tape to keep out dirt and keep in the grease. Then repeat the process about once a year. Use the Urethane strips unless your springs have the seats for the buttons, then use the buttons. They will last a lifetime and be cheaper in the long run.(better living thru chemistry!) Sand or wire brush the leaves smooth using lengthwise strokes only, don't use a disk grinder or such on them. Even small sanding scratches crosswise can start a crack.

Don't use teflon, use the urethane strips with the raised edges. Teflon is not good under compression pressure and will slide out from in between the leaves. Mid Fifty calls it polyride and sells it for 25.00 a roll to do two springs. Make sure what you buy is the right width for your springs.
