There are several different opinions and several different methods. A search on this forum and/or your internet browser, will yield a lot of reading on this issue....

For my part, I had a 2000 carbed bike with only two small openings in the tank. Some use chemicals, I used the #8 shot method.....

I removed, emptied, and rinsed out the tank. I removed as much of the peeled "chips" as I could. I made sure there was no fuel and/or fumes left in the tank. I put #8 shot in both tanks, and sealed up the openings with tape. I tightly wrapped the tank in a number of quilts. I then put the wrapped tank in my dryer. I filled in all the open spots in the dryer tub with sheets. Once I was convinced the tank would only rotate within the dryer tub, and not actually tumble around in the dryer tub, I put the drier on tumble, air only.... no heat.

The #8 shot slides around in the tanks, acting as an abrasive to remove any loose liner.

After a while in the dryer, I removed the tank, removed the shot and pulverized liner pieces. It won't remove all the liner, but seemed to remove all the loose liner. I rinsed the tank with alcohol a couple times, then rinsed it once with gasoline (being careful not to blow myself up).

I put everything back together and usually keep that tank full, or rarely under half.... I haven't seen any other loose liner pieces, or had any problems since I did that about five years ago..
