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

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?

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.
