Blocking filter (blue filter) clean?
Posted: Sun Feb 11, 2018 2:05 am
Hi all
The blue filter in my Lunt BF1800? had gone a tad funky - I have already had a replacement one forwarded (no issues there) but I still have the old one. Pic below. Is there any basic way of cleaning it - may be useful as a spare.
Thanks in advance.
