Has anyone tried using a Dremel rotary sander to remove the hardened sealant from the edges of the tubeless tires. It takes forever to pry the junk off with needle nose pliers. But I'm thinking it might just sand off some rubber as well if you get too heavy handed.

Why do you imagine that it needs to be removed?

My thoughts exactly.

If you're using power tools to clean your bike tires, your problem isn't sealant.

IIRC, the stuff is water soluble. (I don't replace sealant. My mechanics do.)

b88

I keep thinking same thing but then I go on you tube and .....

If you can't get it off with your fingers, it doesn't need to come off. The next batch of sealant will seal up the bead.

I've just scraped off the excess boogers with my thumbnail. But I'm not sure that's even necessary. Don't you want the old sealant to stay on the inner surface of the tire?

b88

I pick off any big pieces in the inner surface. I clean up the bead as much as possible. I find excessive old hard sealant on the beads result in faster pressure loss. It doesn’t seal quite as well.

HD3andMe

Why in the world are you popping the bead in the first place?

b88

While I was changing sealant, might as well take the tire off and check it out.

It's good practice to pop the bead and clean the nasty stuff out. I never do on my own bikes though, I'm curious if some of the older tubeless tires have grown squids.

I think a dremel is more likely to do damage to a tire than help. Sure, the tire is getting marginally heavier over time as sealant dries on it, but probably it will wear out before that's particularly significant.

Sealant doesn’t need to be changed.

if you need to add some, add it through the valve stem.

HD3andMe

It’s a meaningless exercise. Hardly good practice.

I'm just looking for justification to buy new toys. . Yes the sealant on my other bike have grown squids. I kept puncturing the tire on purpose to see how well the sealant works. Well the dynaplugs sure work. Then I kept pumping it back up with CO2 cartridges. Fastest way to ruin your sealant.

I unseated the tire because I'm using race sealant, which may or may not plug up the valve stem.

HD3andMe

It doesn’t. You remove the core to add sealant.

b88

Ya my LBS told me not to inject it through the valve. The right method is whatever works for you.

HD3andMe

That’s laughable. Thanks for that.

Stan's cleans up with water.

Injecting it through the valve works for me.

I'm starting to understand why some posters believe that tubeless is sooo much work -- there are a bunch of people making it way more work than it really is.

Stans specifically recommends against injecting their "Race" sealant through the valve, fwiw.

DrIsotope

I swap out tires every now and again, and all of my bikes are tubeless. I was doing an unsupported 140 miles day after Xmas, so I put on some tougher rubber in place of the happy-medium-style that were on the bike the day before. My method? Take off the sealant filled tire, take it outside, spray it with the hose, fold it up, put it away in the old Igloo Cooler that serves as my tire storage humidor (which currently has 9 or 10 pairs of tires in it.) The stream of water from the hose will take off ~95% of the sealant. There's no need to get a tubeless tire any cleaner than that unless you're planning on selling it.

b88

Thanks. All the same I will stick to recommended install.



Stans race sealant.

Koyote

You do you, I'll do me.

But perhaps just ponder for a moment: what will happen if you inject it through the valve? How is the end result any different than if you pour it directly into the tire, other than that injecting it is easier and takes less time?
