Err, I don't think alcohol based cleaners are advised.

Here's a cheap alternative: get some alcohol free toner (can buy from Guardian/Watson's- Simple brand, big bottle abt RM20 I think), and clean with cotton swabs.

I'm telling u guys, it works like a charm!

Have used it to clean my old white iBook and also use it to clean the screen of my mobile phone.

yea, brand name is: SImple. Light Green transparent bottle.

Really, realy worked- my iBook was quite dirty, then i used this with some soft cotton n cleaned, and it became super-clean

Yep, that's the one

Just use a bit of toilet tissue or a cottonball and it'll do the rest
