1 part of paraffine (candle stuff)
1 part of motor oil
1/2 teaspoon of graphite powder
Melt paraffine slowly, add oil + graphite. Stirr.
Insert well degreased and dried chain. Stirr, watch bubbles come out of chain links.
Pull chain out of hot mix with pliers and let hot mix drip on newspaper. (Beware! Hot!)
After cooling down, brush off excessive wax mix and wipe with clean cloth.
Enjoy riding a bike with a perfect silent chain that does not catch sand and stays dry & clean for many hundreds of miles.
