I'm looking for some guidance based on experience for patching a Hutchinson Sector 28 tubeless tire. Yesterday I returned from my ride and noticed orange splotches on the bike and on me that was clearly Orange Seal sealant. The rear tire pressure was only down 10 pounds so I pumped it back up to 90 pounds and assumed that the hole was plugged by sealant. The pressure checked OK this morning before my ride but about 2 miles out I heard a hissing noise and the pressure dropped way down. I could see sealant bubbling on the tire while I added air. I got the bike home and removed the rear tire.

I've washed the wheel and tire but with the sealant residue it is difficult to see much of anything like a hole or a cut. I can see a small wire puncturing the tire but that seems like an unlikely source for the type of air loss that I experienced. It isn't like I can pressure check it in water like a tube. If I need to remove the sealant residue, what is safe to use on the inside of a tire? New to tubeless and need advice please.
