Ceaning

Any microfiber cloth is fine (wet the cloth with a little water) The case and screen will not scratch unless there's something hard on it that will rub into the finish. Suggest you blow out or vacuum the air intake on whatever model you have. The older models with Ram on the bottom are notorious for building up caked dust layers that cause heating problems if left unchecked.

 

I have had my iMac for a year, but have never vacuumed the air intake? Is that a recommended cleaning practice? How often should this be done?

 

Nice typo ;-)

 

cleaning

hi this is best way of cleaning screen but all i would add is that for best results use distilled water on micro cloth then dry with clean micro cloth tap water will leave smears especially if in hard water area .

 

Bad water is possible, so agree. Endust For Electronics works well too.
