I bought a secondhand bike from marketplace which came with a tubeless setup. I have never ridden or maintained a tubeless bike before. The inside of the tyres were covered with dried up sealant and wondering if there's an easy way to get it off?
Considering the price of a new tyre coating around $30 each, I wouldn't mind spending a bit of time to get it cleaned. The tyre has alot of life left in it and i don't feel right chucking them in the bin.

It’s not really worth the effort. I would just throw more in and ride until they wear out.
Maybe try scrub it with a brush and soapy water.
Use your fingers or try your plastic plastic levers. If they are metal do not use them
Get to pick’n them boogies! 🤮
Try those plastic razor blades.
What u/bawdy_george said. Just add new sealant. The old, dried stuff acts as another protective layer.
Trust me. Cleaning this out is not worth it.you will go mad, and waste your whole summer trying to get these clean.

One 48mm gravel tyre sealants. When there is enough sealant and its dry, it will peel of easily.

You can get it off by rubbing it with your fingers. It won’t ever be perfect but you can get most of it off. The real question is whether the effort is worth it and the answer to that is only if you have OCD or are racing in a grand tour where the few extra grams might matter (and in that case you have a minion to do this for you).
Just ride it bro.
I’ve literally never removed sealant. Just add more and go ride.
My recent method takes time (less than ah hour). I use a basic microfiber cleaning cloth about 10 in. x 10 in. As you show in the second photo, invert the tire and rest on a flat surface. Fold the cloth, then scrub the dried sealant vigorously. No water added. the loosened dry sealant sticks to the remaining dried sealant. Work on about 4 inch sections at a time. Like I said, it is not a fast process but it removes 98% of the sealant. make sure to scrub the bead so it seats properly in your rim. Another method was to use a natural gum eraser but those are smaller, so it takes longer.
It does matter what the interior texture of the tire is, sometimes the sealant melts smoothly into fine texture sometimes it is barely sticking. One technique may work better than another because of the type of texture.
Rubber eraser (like for suede shoes). Takes time but works.
I have same issue how to get off this thing,I’m looking to use TPU rather than this shit!
Take it in the shower with you and give it a clean with a kitchen scrub. Get it nice and hot and do a few passes, it doesn’t take long at all. You dont need to get it all off, just scrape off the bulk. As my dad used to say: “that’s good enough, we’re not building a church”.
You can buy natural rubber Adhesive Residue Erasers – they work very well on sealant. At least clean the beads, but with these yellow pieces of rubber you can also clean the whole tire. It’s just simple scrubbing.
How does that even happen?
I’ve ridden tubeless for years now. Usually just put sealant in new tires, top it up half-way through their life, and then pull the old ones off. It never looked like that.
The only thing I can think of is the previous owner used CO2 to inflate the tires regularly and didn’t use a CO2 compatible sealant so it hardened in the tyre.
I would just throw this one out. You will not be able to clean it completely at this point, I don’t think.
Plastic scraper, then isopropyl alcohol. Takes a few minutes per tire.
Cheap crappy bottom bracket spanner from Amazon and scrape it off . One this shape. https://amzn.eu/d/0ixfvnun
Bottom bracket tools work well to scrape them out
Washing up sponge and bike cleaner or washing up liquid. Just get the big bits off then leave the tyre to dry.
Pressure washer has worked really well for me.
for folding bead tires you can flip them inside out then use a brush or scraper.
Look for a decal sticker remover on amazon not expensive can fit to drill removes sealant.

I’ve tried this, it works, but it didn’t work this well for me. But it worked.
Running water and a rag, focus on hooks they are most important and harder to clean both on rim and tire, so they would seal. It’s 10 minutes job to get it to like a new condition. Dry, add new sealant and it’s good to go. Don’t listen to people which recommend to throw it to bin. It’s unnecessary waste if thread is still good, just check tire wear indicator.
