Happy New Year when it comes.
Now GT85 doesn't have telfon what is the best thing to use. Do I stick with sub par GT85, Duck Oil, which I have a 5L tin off ( it's in my will to my lad. Ha!) Mortis MD4. Which came recommended by the KTM guys. Or DW40.
I like GT85, and use loads. I bought about 80 quid worth when it changed using the BC discount at Halfords making it very cheap.
Any thoughts on a a general purpose light lube/rust inhibitors/cleaner for the moving parts?

Hmmm, I have gt85 and dont see the need for it anywhere on my bike.
Only aerosols i use on my bikes are mucoff silicone shine or juicy lubes fork juice but just for a quick squirt on the stanchions/dropper when cleaning them up
I have a number of bikes and no GT85.
Am I doing it wrong?
As per this video. Had worked for a long time for me.

Interesting, I’ve been aware of this technique for some time, but not seen anyone else share the same approach with enthusiasm

I’m lazy with degreasing, particularly with my commuter, I will now give this a go with an existing can of either Duck Oil or MO94 and see if this works as both the degreaser and lubricant

When did they change the recipe? I have several cans waiting to be used but don't really use it on the bike that often. I might occasionally flush out a length of gear housing or a bearing. Perhaps a little bit for steel bolts after washing the bike.
Weldtite TF2.
I don't use it, or GT85 for that matter, but my local bike-hire shop uses it to prep bikes.
Just continue using GT85? Teflon is not required for lubrication/cleaning/rust inhibition.
It's really bad for the planet... that's why it has been removed.
Mo95 muc off
Cheers fur the information and suggestions.
So long as it still smells the same...

What @SYZYGY posted.
Aerosol cans are bad in general because you're just dumping a load of hydrocarbon directly into the atmosphere for no benefit.
PTFE we now know to be bad for a multitude of reasons. Both from a chemical perspective and you could literally swap "contains PTFE" for "contains microplastics", because that's what it is, ground up plastic.
I have a few cans of GT85/MO94 in the shed because they came with the basic 'gifts for cyclist' idea that is the cleaning kits from halfords and muckoff. And they do serve a purpose occasionally, but I've probably had the oldest can almost 8 years.

Have a look at the ZFC charts, which show chain wear. WD-40 is around 0.5 wear after 3000km, hot-wax is around 0.05.
And Ceramicspeed test for drag, GT-85 actually comes out worse than straight WD-40, both in the 7-8W of drag, straight paraffin wax (i.e. hot melt wax with none of the additives or marketing) is in the 4's. Even more impressive, most lubes lost an extra ~4W in their longevity test, wax actually got about half a watt faster as it bedded in.
GT85 is a funny product. Its too thin to lubricate anything, doesn't leave a robust or durable film for rust prevention, but is enough to contaminate brakes so can't really be used as a water dispersant. I have a can for washing greasy things during general maintenance, but I find either WD40, Isopropanol or a degreaser better, depending on purpose.
TBH I wonder why I started using it. Maybe when I was a new rider it was recommended to me. And then of course, it's got PTFE in it.
Over 3000 miles on my ebike chain, lubricated and cleaned with nothing but GT85 for 4 1/2 years. It's now getting close to 1 on the chain wear thingy, so I'm thinking of changing chain, cassette and chainring. I clean the motorbike chain with it too, but wipe that with gear oil afterwards. 11,000 miles with no adjustment yet. Big twin, too.

Somewhere over 2200miles on my newest chain using homebrew wax (50/50 paraffin wax and gearbox oil to soften it and stop it flaking off*), the chain checker wouldn't even drop into the rollers last time I checked.
So it seems like those results back up ZFC, your GT85 chain is worn in ~5000km, the waxed chain is still at zero within the margin of error of the tool at 3500km.
*It does contain teflon powder amongst other things. If I ever make another batch I'll switch to soy wax, hydrogenated veg oil and maybe some graphite so it's basically natural. Based on the ZFC and CS testing it doesn't appear the additives actually add whole lot of value. It's an IF though, I blended about 2kg of it and still using the first little tub 2 years on 😂.
More of a body spray than a deodorant. It’s better than Lynx.
Only used on door hinges here now. I used to use it a lot on the bikes, but there’s something far better and less polluting for every bike related job.
I’ve only ever used it after washing the bike, on the chain, to disperse water. MO94 serves much the same purpose. Straw plugged into another spray cap which sprays down onto the chain thereby avoiding the brakes.
