Can you recommend a cleaning solution (spray) to use with Microfiber Cloths?

We do not recommend using liquid cleaning solutions or liquid screen cleaners:

1.- They are not necessary to accomplish lint & dust free results (save money)
2.- Most of these liquid screen cleaners contains detergents and substances that
destroy microfiber cloths and their cleaning absorption properties,
3.- Microfiber cleaning cloths are an environmentally-friendly cleaner if you use
them dry or with just a little water or humidity.

We do recommend you use a few drops of water (distilled is best) to remove tough
spots and then removing any residual humidity with a dry microfiber cloth.
