I remember reading years ago that a 50/50 Isopropanol  / distilled water mix was the best and now this is not the case?

nothing changed, this is still fine. i usually use a very damp paper towel though, but only rubbing lightly, then wiping with a microfiber cloth with a bit more pressure.

I am surprised to read that article, but possibly the author glossed over something very important.

There are three common alcohols that might be used for cleaning -- ethanol, methanol and isopropyl.  Ethanol is somewhat aggressive, methanol more so, but isopropyl is not.  Isopropyl is, in fact, used for cleaning magnetic heads in tape drives.  It is also an excellent remover of soldering flux, and removes human skin oils from things such as cell phones without damaging the surface.

I would not fear to use isopropyl on any kind of electronics, as long as it is applied (as jlamb87 has said above) with a soft cloth or cotton swab.  It may take several passes (hardly an aggressive solvent), but it gets things clean.

I use it straight out of a Walgreens one-quart bottle, which is cheap and about 90% alcohol.  Just remember to pour the alcohol out onto the cloth or swab, so that the contents are not contaminated by contact with a possibly contaminated cleaning item.
If it's a matte screen that's fine, but if it's a glossy finish don't use alcohol as it can damage(dries and clouds) the glossy finish. I learned this lesson the hard way. To clean a glossy screen I use a barely damp microfiber cloth, this also works well with the matte screens as well.

jamietoner makes a very good point.  No matter what cleaning method is applied, test it in an inconspicuous area first.
