Several years ago, I bought my 90mm Sumicron from a Seattle Wash. dealer, at
a VERY good price, because it had a front element smudge that they could not
remove.  I tried lens tissues, the system above, in fact everything I could
think of.  Nothing worked.

Then on a whim, I bought one of those (then new) "magic" micro-fibre
cleaning cloths that you use dry.  I breathed on the lens and gave it a
gentle wipe.  The smudge was gone! My cloth was from Pentax, but they're all
over under various names. Sizes & prices vary.  Best $10 I ever spent!

Side benefit: no risk of any liquid seeping into the lens' interior. And
when the cloth is dirty, you throw it in the wash!
