Joe and I commenced the cleaning party on the two SM2 this morning. It took a couple of hours to pre-clean the tapped holes on each mirror. Very little debris came out with the Liquinox swabs and, as usual, rinsing the Liquinox was good, clean fun. Once we were satisfied with the pre-cleaning of the holes, we stopped for lunch. After lunch, we prepared the isopropanol bath in the designated pan under the fume hood. We wanded the tapped holes and then each of the honey-comb pockets on the back of the first mirror. Next, we transferred the mirror to a flow bench and removed the Teflon disk so we could perform the isopropanol rinse/N2 blow-off of the optic face. After a brief inspection, we replaced the Teflon disk and set that mirror aside. Then, we ran through the wanding etc. on the second mirror, inspected it and replaced the disk. The mirrors are setting on the flow bench until they are needed. 

We came out and talked to John about what he wanted us to do WRT FTIR. John asked to see the procedure that we had followed and asked a few questions. After hearing our responses, he is willing to accept the SM2s as clean without an FTIR.
