Boiling, and Boiling, and Boiling

So from the beginning I have been boiling the caps so that they get cleaned and so that I can remove the plastic liner under the cap. I use sharp tweezers, an old pot, slotted spoon and an old dish rag, started out a little rough, but I have gotten the technique down and have learned which caps are easy (older Budweiser caps), which ones are difficult (Blue Moon caps—too bad they are one of Kevin's favorite beers) and which ones are near impossible (Magic Hat caps—I don't even bother to try anymore!)

Then this morning I woke up with the thought that I was still going to boil the caps, but would pass on removing the liners. Since I am intending on nailing the caps to the board for the fish I really don't think the liners will matter in the least bit. Why still boil them then? To get them clean, and not smelling like beer. If/when I do make coasters though I will re-boil any that still have liners in them and remove the liners because I will be gluing slices of wine corks to the bottom of them to protect any table tops they may be put on. I figure gluing straight to the underside of the metal cap will be much better than gluing it to the liner that can potentially fall off.
