Lighter Fluid is Naptha. Instead of buying it in small cans that are expensive, you can buy it in quarts in the paint solvent section of your local Lowe's or Home Depot. Locally, we've got Menard's and their Naptha comes with a metal cap instead of those annoying plastic pop off tops. About $6 a quart. Works great to clean the outside of bodies too and any sticker/decal goo.
