You probably "loved the old one to death" too Angus:

I hate to break this to you, but alcohol dulls most plastic lenses over
time.  Every time you cleaned it, you killed it a little more.  It is a
very short term fix unless metal or glass is being cleaned.  Even then,
if there are any additives they will leave deposits on the surface.

To summarize: 1) Never use alcohol to clean plastic.  2) Use only
isopropyl, never ethyl alcohol.  3) Avoid additives such as wintergreen.

By the way the the dull lense won't stop the beam, just make it slightly
weaker in a world of micro-thin tolerances.
