I went out for a ride yesterday in what appeared to be the inside of a cloud. I had such a lot of misting on my glasses that I had to take them off for the climbs as not enough speed to clear them.
Can anyone recommend an anti fog spray or am I better off sticking to washing up liquid and spit?
Apparently the Muc-Off one is decent, I heard this from a friend though and have not personally tried it.
I seem to recall that this topic has come up before and the general consensus was for something designed for motorcycle visors, not being a motor cyclist myself I have no idea of any brand names though.
I haven't used any for ages, but this stuff always used to be really good on motorcycle helmet visors. I can't see why it wouldn't work on mtb glasses. These days I use a pinlock visor insert which negates the need for ant-fog spray.
I use the muc off one for swimming goggles.
I use wax car polish on inside and out of visors for TT racing and it's faultless. Worth a try if you have some kicking about
Rain-X? I use it on my car screen, but not on the inside, because it’s a heated screen and if it starts to fog I just turn it on or adjust the demist.
I wear Oakley M-Frame Si glasses on the bike, which are pretty tight fitting, but I haven’t ridden in cold weather yet, so I don’t know if they’re going to fog up. If they do, I’ll try Rain-X first because I’ve got a spray bottle of it kicking around.
My mate who is a bit of a gadget/niche freak had some and let a few of us smear it on our (you can also get a spray) goggles for a rather wet weekend at Dyfi.
By lunch I was sold. Where I would be going for a fresh set of goggles, had me riding the whole day in the same set with zero fogging issues. It also causes the rain and mud to bead making it far easier to clean them off.

Rainex is pretty pungent hydrocarbony stuff isn't it?
Not sure i would be enclosing my eye with those vapours.
I wouldn't expect Rain-X to work very well, it's to designed to bead water and then relies on air flow to push that away from the surface. If there's no air flow and not enough water to create large beads that run off you'll just have a fine misty coating build up.
I use Muc-off myself (although very rarely need to), it's OK but not some miracle solution (can still fog up a bit in extreme conditions)
You have to apply it reasonably frequently, but a teeny drop (and I mean teeny tiny) drop of dish soap liquid smeared onto your glasses and then polished will give you a couple of hours worth of anti-fog and beading.
I use this stuff on swimming goggles (training twice a week). Works superbly. Can't see why it wouldn't work on riding glasses, yet to try as I don't often have fogging issues.

I use the Nikwax Visorproof. It's a little expensive but a little goes a long way, I got my bottle in about 2004 I think. Lasts pretty well, works very well, keeps mist down and also helps water and even mud slide off. On pushbikes you don't really get fast enough for it to really kick in- teh way water just streams off a motorbike visor is awesome.
The only real downsides I've found is that it's in that awkward "lasts long enough that you forget to redo it" space so every so often I get caught out by that. And if you get it on a vinyl floor it's the slippiest thing in the world and a little hard to clean off!
But tbh with sweaty humans involved it's a really difficult task, sooner or later anything wets out so the best option of all is spare glasses imo. And kitchen roll in a convenient dry pocket.
I used Mucoff over the weekend it failed almost immediately on my goggles!
For my swimming goggles I wash them in baby shampoo when they start playing up and works, so might try that if issue persists.

RainX do a specific anti-fog product, it's okay, not brilliant but it does work to an extent. It's really meant for car mirrors etc.
