OK, I admit I am a smoker. Im trying to quit, its hard though...

So I have several LCD monitors that have accumulated grime from cigarette smoke over the years. Every so often I take a soft cloth and dip it in mildly soapy water. I gently wipe the screens down to clean them. It works, however its an extremely slow and tedious process, as it takes many passes to get the screens clean.

Is there a better alternative out there? Is there a home 'remedy,' or even a tested commercial product?

    The best solution I have ever used for cleaning my LCD is baby wipes. I have cleaned crayon, colored pencil, food and liquid of all types, etc that my kids have left on my screen. I'll admit I have not tested them on smoke residue, but if they can get crayon off with ease, smoke residue shouldn't be that bad.

You can either use an equal ratio of distilled water and vinegar or isopropyl (rubbing) alcohol. Be sure to use a microfiber cloth or anything non-abrasive. As a general rule of thumb, you don't want liquid to drop/drip on the monitor as it can get inside and destroy it. Just apply a small amount to your cloth.

  • I thought alcohol on LCD screens was a no-no.

  • It depends on the coating used on the lcd screen itself and you are correct some manufactures, including Apple, warn against it as it can damage the outer coating. I have used it on Dell branded lcd screens with no problem, but keep in mind, I am using a 50-50 ratio of water and alcohol. The safest method is vinegar if you are concerned and/or are unsure of the manufacturer warnings. Aug 22, 2011 at 18:20

I am not smoker, but I use some cleaning liquid for LCDs which was shipped with some microfiber cloth. I use product called "D​-Clean Premiu​m Notebo​ok Clean ​- Crysta​l Shine", but we also have something similar by Belkin (these do not contain alcohol). I think it could be also effective for the smoke particles. The set of 20 ml cleaning solution in spray with microfiber cloth costs approx. about 8 USD in my country :-)
