I am a scientist just not a rocket scientist. I deal with organic, inorganic chemistry and do research in chemical engineering.I also ride just about every day weather permitting,I like Jack Daniels, wet T shirt contests, biker bars and pee in the back yard too frequently according to the wife (have a tall fence).

No I DONT have a pocket protector or wear dark horn rimmed glasses. I'm so ugly that when dating, before I got married, the tide would not even take me out. My breath is so bad that when I exhale, my teeth duck! and my wife tells me that my package resembles a grub worm in a turtle neck. Hey atleast it still works!
I also teach and found that humor helps to retain attention.

Now that we have that straight..I hope this helps.

Lets start out with the actual ingredients found in a spray can of Pledge.

Please note that the base formula will be different being dispensed from a spray can or pressurized aerosol vessel due to the fact that a "propellant" is needed to transfer the product from the container to a surface, in this case lets say a fender or a windshield. A trigger plastic spray container would not require this propellant additive.

For the purpose of this discussion, I will list the information relative to Pledge in the aerosol spray can as it appears to be the most common used by others on this forum.
The base ingredients are:

1. Naphtha, petroleum, light alkylate 5%-10% or (isoparaffinic hydrocarbon solvent)
2. Polydimethylsiloxanes (Silicon oil) 5%-10%
3. Water 70%-85%
4. Butane1% -5%
5. Isobutane1% - 5%
6. Propane1% - 5%

Now we can breakdown what these are and what they do.

The first ingredient is:

1-Naphta,petroleum,light alkylate.
This is a hydrocarbon solvent-based dispersant formulation which combines oil penetrability. In other words remember the label says "smear and smudge proof"? These are the ingredients that will break down and remove the smears, finger or dermal tissue oils. Criminals take note.. use this to eliminate finger prints. Just dont be a dumb azz and leave the can behind!!

Now, what is a hydrocarbon?
A general term for organic compounds which contain only carbon and hydrogen. They are divided into saturated and unsaturated hydrocarbons, aliphatic (alkane or fatty) and aromatic (benzene) hydrocarbons. Crude
oil is essentially a complex mixture of hydrocarbons.

To break it down even further, I will now define an organic compound.

An organic compound is any member of a large class of chemical
compounds whose molecules contain carbon.
What is carbon you asked? I knew ya would!!

Carbon is a chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent (a state of an atom with four electrons making four electrons available to form covalent chemical bonds.)

A chemical element is a type of atom that is distinguished by its atomic number; that is, by the number of protons in its nucleus. The term is also used to refer to a pure chemical substance composed.

What does this all mean?? It is a pure chemical substance.
Why is it in there? Remember the finger print? It is a solvent that removes oily residues. This is the cleaning agent in the product.
Look at the can.."It dusts and cleans". this is what makes it clean/remove dirt,grease,oil,grime.

Dont try it on bodily fluids!! Get a bucket and warm water mixed with a 50:50 bleach solution. Ooops sorry, got a little carried away there. I mean...I have never had to do that detective sir. Hey I live in Florida and we shoot first then ask or answer questions later.

That was the more lenghty one. The remainder are relatively simple. If you are still reading at this point, thanks for bearing with me.Go grab another beer! I will summarize at the end and compare to other products on the market in terms of ingredients, costs and results.

The second noted ingredient is:


2-Polydimethylsiloxanes or Silicon oil 5%-10%.
This is silicone based oil. The molecular structure of this is such that friction is significantly reduced. This nifty additional ingredient is also the reason why the ..refer to label again.. NO WAX BUILD-UP!! Silicone will blend with it'self and not mix or layer with other chemicals.
It does however have the ability to **** bike painters off due to the fact that it needs to be completely removed proir to coating with paint. If not...start all over again. It makes surfaces slick so that nothing sticks. It also provides the shine to the surface.
This chemical is also present in 95% of products us bikers use on our scoots such as Armor All, Meguires Wax and STP Son of a Gun just to mentiion a few so if you are worried about using Pledge in the past on your bike, you may alraedy have and just did not know it.
This silicone oil is also an ingredient in Right Guard deodorant, baby powder,Desitin, Gillette Dry and several moisturizers and creams. This is why Pledge does not contain wax, they use this instead.
Makes me want to try it with the goa....wife!
To the guy that posted about the fella steping on his fender and sliding off...about to 5 drops of this in a drink will cause lets just say possible incontenence" which will then require the need for additional Desitin with the same ingredient to help that diaper rash from the copiuos ammounts of passing solids!!! Great stuff ain it?

The third ingredient:

3-Water. This acts as a dilutor. Kind of like "filler" in cheap dog food but in liquid form.
Cant use the product undiluted.

The remaining butane, isobutane and propane are the propellants that assist in expelling or propelling the liquid product from the can. Sorta like lighting a fart. The methane is the fart building under pressure and the propane, butane provides the ignition source. Both pledge and a good fart will produce a romantic blue and orange flame. Or so I have heard, maybe seen...OK OK I have done it! Kinda like putting your tounge on a 9v battery. You know you are gonna do it eventually when no one is looking. Try chewing aluminum foil!! Nah...dont do that either.

Other ingredients asuch as aromatic compound like orange, lemon or any other organic scent additive can also be incorporated.
If you are still with me on this one, you are either killing time, Fu&^*% off at work or the **** filter is working real good on your computer. If neither one... thanks for sticking around.

Now with this little snippet of knowledge, how does one apply it to everyday living.
If Martha Stewart says that a prison panty liner work just as well as a microfibre cloth stop reading. If not..please bear with me for I am almost done.
Several products out there are costly for several reasons. 1 because of proprietary ingredients/raw materials, 2 advertising costs, supply and demand and product to market costs. What will the market bear? I have always compared ingredient when shopping. Silicone oil is silicone oil, Pepto Bismal, for the guy trying to stand on the fender coated with silicone oil is pink Bismuth...same thing!
Pink bismuth is MUCH cheaper.

I heard of a product called Plexus. A great cleaner and conditioner for Lexan. At $15.95 for a 13oz can versus an 18oz $4.99? can of Pledge? I have not bought or used Pledge and do not know the actual cost I am sure it is not even close to this other product.

In summary:

• Will not damage finish
• Will provide a nice shine
• Will not build up or layer
• Safe on windshield. No alcohol or amonia
• Safe on chrome
• Also has some (although not real good) anti corrosion properties. I use Boeshield T-9 for this application.

One precaution!! Flammable! Do not use around open flames or on hot pipes or other hot components. Do not get on or use on denim ar matted finishes!!

I would also highly recommend that a wet or water wash, or a soft wetted cloth, (I use warm clothes because the heat helps soften bug guts better than cold) be done or used first to remove surface debris and particulate from the soon to be applied to surface, fenders, gas tanks,side panels. This will reduce potential scratching of your paint.

Well, I hoped this helps. Like I said, I have never used "Pledge". But I have applied the same ingredients in Pledge (just under a different name...Maguires Wax) on my bikes not knowing it, and they have all looked great!

Now get off the computer and spray your bike with Pledge!, or go riding...
