Re: Kreen and film cleaner
I'll get some air, that seems to be the best option along with the alcohol for the Kreen.
I'm happy to hear about the Kreen replacement timeframe. I may be in need to purchase
some as I've noticed some week spots.
Thanks again for the advice.

According to Boxcar's new website they change the Kreene every couple
of days or so. I change it reluctantly whenever it starts to fail on
me, every couple of months or so. You must be doing something right.
