I'll have you know I've never got sealant on my carpet. Just oil and grease and wine and beer and all manner of food.

Expensive bottle with carbon strands hosed everywhere? No thanks

TL/DR: Don't. It is absolutely awful - the worst bicycle product I've bought in years.
In full:
installing it is a pain, because it clogs valve cores. So you have to partly take the tyre off. If you then don't get the tyre to seal first time, the sealant will have gone jelly-like, and is ruined. You then need to clean out the tyre and start again.Next, it doesn't work very well. It didn't seal the most basic of holes, and when I got the tyre off to put a tube in, I saw why: most of the carbon fibres had formed into little stalactites on the inside of the tyre, rather than dispersing.
I say 'most' of the carbon fibres, because the remainder clog your valves, and topping up tyre pressure becomes difficult, then impossible. I had to replace both valve cores in less than a month.
I think I threw out the stuff I have left. If I didn't and it's still somewhere in the garage, you can have it for postage if you really want to try it, but trust me - you're better off with pretty much any other sealant.
I'm glad that's off my chest :-)

Anyone tried Silca ultimate (the sealant with carbon strands in it)?
I have heard it “just works” from mechanics experienced in tubeless and that sounds a lot better than “Hippy’s carpet bukkake” of yesteryear.
Caveat, I haven’t used tubeless on anything but am seriously thinking for gravel bike but also wondering for road bike (28c and 70psi) the days of riding 23c at 120psi on t’road have gone.
