If the cost of products such as White Lightning is prohibitive, try this special mix I learned from a good friend. It's not quite as good as White Lightning but it works. Buy a quart of xylene from a hardware or paint supply store ($3-$4). Then buy a box of paraffin from the grocery store ($1-$2). Use a plastic 32 ounce soda bottle to pour the xylene into, chop up 2-3 blocks of the paraffin (try 2, if it doesn't leave a waxy residue on your fingers, use 3) into small chunks, put the paraffin pieces into the bottle with the xylene, shake occasionally and give it a day or two to dissolve. Fill a 4-6 ounce plastic squirt bottle to take on your rides and use as needed. For $4-$5 you have 20-24 ounces of chain cleaner/lubricant. I carry a 4-ounce bottle whenever I ride. When I hear my chain I apply a bit of the mix for a quieter, easier ride. You will ride easier and your chain, related drive train components and pedals will last much longer.
