Some on the online forum recommend using rubbing alcohol, is that true?

作者: 快樂牛郎 時間: 2011-5-26 22:52

yes
$3 at any drug store

I rarely use any kind of liquid form cleaner, cuz no matter how hard I tried, there would still be some unwanted water marks left behind. You know what? Something like 菊花牌底衫 is the best! ^^

i haven't seen any brand name lense cleaning fluid for $20. the one i use is branded and it's $8 for 10oz. But I compared it with a $3 no-name and it appears the $3 is even stronger and more effective

but of course you still want to avoid wet based until it's necessary

The $3 one you have just mentioned is rubbing alcohol or no-name lens cleaning fluid?

作者: siumaibb 時間: 2011-5-27 09:24

90% - 98% rubbing alcohol

they say the higher purity the better
but i found 90% working better than 98%

For rubbing alcohol most of them contain 70% isopropyl alcohol and 30% distilled water.

Are you adding 10% distilled water to make it 90% rubbing alcohol?

I actually meant 90% isopropyl alcohol
if that's no longer "rubbing", then excuse my english

Thanks...
BTW, posts on some photography forums suggest that don't use pure methanol or isopropyl alcohol, they are just too strong to dissolve the glue between the lens and the barrel.

not sure about methanol but isopropyl alcohol is not a strong/corrosive chemical

Leica uses 100% isopropyl alcohol themselves on their gears
