WD40

oops.....

WD40 is fantastic stuff, it IS a lubricant, but it is not a very good one as it is so thin and dries off very quickly.

ACF50 and GT85 are completely different, they are silicon based so leave a dry layer of silicon which is why they protect things much better for longer.

WD 40 is good stuff, however i have been banned from using it at work as it does contain water, yes it does repel water but if it sits in say a electrical plug it can still rust. GT85 is far bette,r to simply spray on and forget, it polishes plastics and gets a good shine on trim etc. Its about the same price and liberally spray it all over my bike apart from discs, i have done for 15 years and the stuff is superb. It will shine up dull black items and stays on longer than WD40. I also use GT85 on my pushbike, mower, jetski,and door locks and hinges etc. First class spray.

According to the WD40 website:

While the ingredients in WD-40 Multi-Use Product are secret, we can tell you what it does NOT contain. WD-40 Multi-Use Product does not contain silicone, kerosene, water, graphite, or chlorofluorocarbons (CFCs).

Sorry My bad! I thought it was a variant of GT85! They have similar uses.

i always spray it over my engine and header pipes after washing it will smoke when you next start up but it quickly burns off

And it smells LLOOOOVVVEEELLLLLY.

WD 40 is also excellent and getting the BBQ going. But WD40 has many uses but that's not what it is formulated for. It's made as a penetrating fluid and light lubricant. It also happens to be a reasonably good water dispersant but is not dialectic so over use is not good for electrics. If one wants to polish their bike then one should use wax as that is what it is made for. People just use WD as they find it quick and easy and it saves buying wax.

Yet again GT85 the same thing it's a lubricant not a polish or protectant.

ACF50 is another kettle of fish as it is designed as a protectant, a coating that covers everything to protect through the winter months from the salt and grime etc. Or just do as benny does and chuck a gallon of oil at the bike.

gt85 is excellent aswell...........

I use GT85. It's a PTFE (Teflon) based. Also a water repellant. Clean your car dashboard with it - it gives a great shine and smells good!

I use WD40 as a penetrating agent on rusty bolts etc. I don't use it as a lubricant although I might spray rusty hinges etc to wash out the rust and then lubricate them afterwards.

They are both heavily solvent based and I wouldn't use any as a lubricant as such.

I just thought! if we mixed them altogether we would have 3 in 1

This topic has reminded me about something interesting from many years ago (approx 1985), but still relevant as I don't believe WD40 has changed at all.
I have a friend, who used to work in a small video company, specialising in corporate videos. They were commisioned by the WD40 chaps to made a short video extolling the virtues of the wonder oil.
They found all kinds of uses and impressive experiments to show off the properties of this very light spray oil. One experiment threw up a very strange result and the WD40 chaps explained the result and asked that the experiment not be included in the final video.
The experiment was thus:
Three identical pieces of sheet mild steel (approx 6inches by 6inches square and a few mills thick).
> One piece was completely covered in WD40, front and back.
> One piece had no WD40 on it at all.
> One piece was half covered front and back (as if it had been partialy dipped) in WD40

The three pieces of steel were then "weathered" and after a period of time they were examined. The results were surprising:
> The piece that had been completely covered in WD40 was to all intents and purposes free of any rust.
> The piece that had no WD40 on it had a light coating of rust all over it.
> The piece that was only partly covered in WD40 had not rusted where it was covered with oil, but the exposed half had rusted twice as severely as the "control" sheet that had had no oil on it.
I wish for the life of me that I could remember the explanation ... it was pretty simple and I think had something to do with electrolytic action .... but don't quote me!

My understanding of WD40:
It will be absorbed into many rubber-type seals changing their properties. Be very careful! (For example the seals on final drive chains!)
It can possibly effect paint/plastic finishes, although it has never done anything other than leave them gleaming in my experience.
It will dissolve ink (like biro ink)
It is wonderful for dissolving crud and jetting it out of nooks and crannies.
Don't put it on a bicycle (or motorbike) chain, it remains sticky and dust/grit sticks to it.

I always keep a tin in the garage, but often find myself using something else: If something needs oiling/lubricating, then WD40 is so light it may not be the best choice.

Use it for cleaning oily/dirty stuff and for displacing water from mechanical bits that don't have rubber seals in them :-)

Oh ... I have been known to use it inside bicycle brake (bowden) cables to lubricate them!

Cheers All ... I can put off going to bed no longer

...zzzZZZ

it still makes "o" rings swell up and GT 85 dont. Nuff said for me.

So me cleaning my chain with the stuff was a bad idea :ballkick:

Good chain cleaners?

Chain cleaner and an old toothbrush, but mind your fingers turning the wheel.
