How do you clean a rear projection television screen?
Here’s a bit of advice I received from a professional TV calibrator – First blow the screen clean of visible dust with compressed air, that canned computer duster stuff being perfect for the job. Once complete use a lint free type of material such as a cloth baby diaper(preferably unused) or a soft piece of flannel and warm water mixed with a mild detergent such as dish washing liquid in a VERY diluted state. Wring out the excess water till barely damp then apply to the screen but NEVER scrub, instead use an up and down motion with gentle pressure until clean, then dry with a cloth of the same material. This is how he cleans each and every TV he calibrates and has for years with great success, plus it’s hard to argue with someone who earns his living doing such. Oh, as a last bit of cautionary advice make sure you avoid any and all ammonia based products such as Windex as they will do irreparable damage to your screen.
