We have some projectors that have a timer that causes them
to request cleaning every thirty days. That's a real pain on ceiling mounted
units that have to be removed for cleaning. However, we have opened some
projectors after a few years of use to find them totally clogged with dust. This
can get expensive when bulbs and LCD panels overheat. I wish the projectors were
better designed for ease of cleaning. We use regular camera lens cleaning
supplies. I understand that some lens cleaning brushes contain Polonium 210, the
same stuff that did in Litvinenko. Bet it works great.
Now that we have a number of projectors in the
building, I have actually started to pay attention to maintenance. We have no
current issue, but I foresee a day when I need to clean a lens. Most likely from
dust accumulation than from anything else.
We have a number of projectors here and they all
says something a bit different but it boils down to.
Lens cleaning paper
Dry soft cloth (for camera lenses)
Has anyone used anything else and had good luck,
where does one get deionized air?
