They are 28mm. I started with 25 ml but then put in another 30 ml As per Schwalbe suggestion. The wheels they are on are about to go back on the bike after a few month rotation with the spare set, so I’ll top them up again. Its not an exact science as unless you clean them up each time it is hard to know how much sealant remains. However, cleaning and reseating can be a pain so I’ll probably just remove the valve cores and add 20ml.

Yes.
I ordered some muc off sealant today, I plan on removing,cleaning and re sealing.
Should I take tyres off and let the old sealant dry before peeling it off?

I thought tubeless was supposed to be the low maintenance alternative to running tubed tyres? All I ever read in these threads is stuff about sealant loss, air pressure loss, sealant not sealing punctures, and valves getting clogged up. i think I'll just stick to tubes!

But inner tubes don’t work either
And not having to carry spare tubes, pump, levers patches etc leaves more space for fuel 😊. I know I'm living life on the edge by not carrying spares, but I believe in the tech as long as I know it's serviced and fresh.But inner tubes don’t work either
I'm no expert, but I'd just give the a clean with some warm soapy water and a sponge. Remove any debris, let them dry and reseal. Don't think they have to be clinically clean. Just remove a any loose bits

Exactly. Stick with tubes. Especially if you swap tyres about.

Some tyres are a lot more cut-resistant than others. Tough commuting/touring tyres with harder rubber compounds do not slice up easily like performance-oriented roadie tyres. I've hit loads of bits of broken glass riding on Marathons, and never suffered any significant damage. I always avoid glass as much as possible, but sometimes in urban situations the stuff is everywhere and you are going to hit some no matter how vigilant you are.

My plan today was to remove both tyres,clean out the old sealant,refit the tyres and refill with fresh muc off sealant.
Started with the front, got the tyre pretty clean,there was still some liquid left inside the tyre but not a lot, could I get the tyre to re inflate……not a chance in hell. Off to the LBS to borrow his compressor. So didn’t bother with the rear, I just installed 30ml of sealant and left the tyre on the back.
No way are you getting them blown back up without some decent air pressure.
Another lesson learned. Absolutely carrying a tube with me from now on.
Definitely not convinced by tubeless.

Without the right tools you’ll struggle with some TL set ups. Decent tyre levers, blast pump etc are the minimum for taking on TL from my experience. Having now installed many sets (for me and others) i‘m confident in what I’m doing but there’s always a new challenge around the corner with some new tyre/wheel combo.
But there’s no way I’d be thinking about taking a TL tyre off on the roadside, that just wouldn’t make any sense to me.

Only to install a tube 😂
A couple of years ago I was doing a Sportive and stopped to help a guy with a puncture. He had tubeless tyres, but had caught a screw, so the hole was too big for the sealant. He didn't have a worm kit, he had a patch supposed to go inside the tyre, but no levers. We spent maybe ten minutes in the rain trying to get the tyre out with my levers, to no avail. We gave up and he called his wife to pick him up.
But you need to get the tyre out to put the tube in, and we couldn't get the tyre out. A worm kit would have likely worked, and doesn't need the tyre out.
