In addition to GOO GONE, several other track cleaning fluids are available to hobbyists:

	Solvent-based fluids -- Generally, solvent-based fluids leave no residue and have a low flammability rating, a slow evaporation rate, don’t dissolve plastics and are inexpensive. Most solvent-based fluids are acceptable for use with Centerline's products, but should be used with discretion -- flammability, compatibility with plastics, vapors and fumes, should all be taken into consideration. Examples of solvent-based fluids include mineral spirits, GOO GONE® cleaning fluid, 91% isopropyl (rubbing) alcohol, denatured alcohol solvent, tri-chlor, electric motor cleaner, carburetor cleaning fluid, Hampton Hobby Products™ track cleaning fluid, etc.
	Oil-based fluids -- These fluids do leave a residue, but that may not be objectionable. Many of our customers make great claims for their favorite oil-based fluid. On the plus side, layouts that remain inactive for extended periods of time might benefit from a film of oil on the rails to prevent oxidation. Switch mechanisms and electrical contacts seem to thrive with the occasional fresh oil application. On the minus side, you may experience wheel slippage under load or on a grade. Examples of oil-based fluids include Wahl™ Clipper oil, 3-In-One™ oil, Rail Zip™, transmission oil, etc.
	Water-based fluids -- Leave a residue which accumulates and causes the need to clean more often. They can also corrode switch mechanisms, rail joiners and the sides of the rails (slowly) where the fluid might weep over the edge. Water-based cleaning fluids are not recommended at any time. Examples of water-based cleaning fluids include Fantastic™, Windex™, 409™ and products such as "Blue Liquid" track cleaner.

As with all matters of this nature, common sense and reading labels is necessary in order to understand the benefits and/or hazards of any fluid used for cleaning.
