isopropyl alcohol to clean display

When it comes to cleaning displays, be careful; liquid can possibly get between the bezel and the screen; when it infiltrates the display assembly, bad things can happen! To avoid this, conservatively spray the cleaner on to a soft, clean, lint-free cloth first; then carefully clean the display with the cloth. Many manufacturers of displays recommend using isopropyl alcohol diluted with water; basically no more than 50 percent of the solution should be alcohol; the rest should be water. Isopropyl alcohol can be found in most supermarkets and drug stores; the higher the purity level the better, for example 90 percent purity is acceptable; it will say this directly on the bottle. Again, use the solution conservatively, apply it to the cloth first, and try not to get any on the plastic bezel, apply to the screen only. It usually isn’t necessary to clean the screen very often; once every 3 to 6 months is fine unless you work in a very dirty environment. Instead of cleaning the screen, you can also try removing the dust (which can affect visibility) with a soft lint-free cloth or a canister of compressed air. This might help as an added step before cleaning the screen to avoid streaking. There are also various spray cleaners available at electronics stores and online; some of them are simply expensive isopropyl alcohol/water solutions! But personally, for over a decade I have simply mixed my own isopropyl/water solution for use on LCDs, CRTs, laptop LCDs, handheld computers, PDAs, and cell phones, and have never had a problem.
