The guiding rods on my exercise equipment are beginning to rust, what lube should I use and how do I use it?

AIM lubricant has two properties that combine to remove rust and protect from further rust and corrosion.  AIM is a fast acting penetrating lubricant that uses nano-particles to penetrate beneath rust and bond to the metal surface to lubricate and protect from further rust.  Most fitness equipment owners use the spray applicator - either the 4 oz or 16 oz applicator - to apply AIM directly to the guiding rods.  Use a rag or cloth to spread AIM onto all portions of the guiding rods you can reach.  You can wipe off any excess lubricant. You will find that AIM is not like WD-40 or other aerosol sprays that result in a large volume of spray being applied and then requiring cleanup.  A small amount of AIM goes a long way.  All you need is a thin coating on the rod surface.   AIM will continue to penetrate into the micro spaces of the metal surface while providing lubricating protection.  Many fitness equipment owners find that allowing AIM to penetrate overnight and then wiping off any excess lube allows for even better treatment.  Treating the rods once per week provides lasting protection.  More frequent treatment may be needed initially depending on how much rust is present. 

What is the difference between WD-40 and AIM lubricant?  

AIM is a lubricant - WD-40 is a solvent.  There are many people and many internet discussions about how WD-40 functions as a lubricant.  This misconception is perpetuated by the fact that WD-40 appears to lubricate parts that are not functioning properly, but then to get the parts to continue to operate properly WD-40 gets reapplied and then reapplied and then reapplied.  This works perfectly for WD-40 as they sell more product.  The reality is the solvent aspects of WD-40 mobilize the material that was causing a problem with the working part so it appears to function again.  In a short period of time WD-40 dries to leave a residue that includes the mobilized material that was causing the problem originally and the contents of WD-40 that remain.  This residue attracts dust and dirt, carbon, and other materials that are present.  It might even make the problem worse by continuing to add more WD-40.  To use WD-40 properly one should apply it and then remove the mobilized material that was causing a problem and then apply a good penetrating lubricant that will not dry out and leave a residue.  AIM lubricant can serve both the mobilizing function and lubricating function whereas WD-40 can only mobilize materials.  AIM bonds to the parts and does not dry out and AIM does not attract dust and dirt. AIM liquefies carbon and does not allow it to bind again on the part.  This is why users of AIM will note that the black carbon material seeps out and can be wiped away from the part.  The AIM remains on the metal surface protecting, lubricating, and reducing friction, rust, and corrosion.

WD-40 is toxic, hazardous, highly flammable, with the characteristic odor of volatile organic compounds.  PlanetSafe AIM is non-toxic, non-hazardous, slightly flammable, with virtually no smell.
