Pure methanol is a little annoying to source. It seems like you can only buy it from lab supply shops -- not impossible to get but not exactly at the local Walgreens.

All of this feels a little overkill for eyeglasses. Dish soap works very well (it's concentrated so don't use too much or you'll be rinsing a while) and most people have it in their kitchen. I personally mostly use hand soap in the bathroom -- works less well if it's a soap with lotion but most places don't have that. The added benefit is that you can do it almost any time or place without thinking too hard.

+1 I just use warm water and hand soap, followed by rinsing and then a gentle wipe with a soft microfiber towel (the kind you'd buy for washing a car actually).
