How to maintain and clean a projector lens?

[bbasera]

Interestingly found this, which recommends plain distilled water and clean q-tips. The important point seems to be the way the cleaning motion matches the way the actual lenses are polished.

Thanks

These days, most manufacturers' lamps are powerful enough to shine through normal dust accumulation. I also recommend IPA if there is a need at all. I don't touch the lens with anything.

Most projector owners know how delicate the equipment is and maintain them with utmost care. But dust will find its way no matter how careful you are.

In my opinion, unless it is really bothering you like blurry images ( highly unlikely ), don't touch the lens. ​

Hi for TW9400 though it automatically covers it when not in use still I see some deposit. What is ipa??
