I use Mrs. Meyers which isn’t as greasy or filmy feeling as something like Dawn. You want just enough dish soap that it’s a little sudsy but mostly water. (This is actually a great all purpose household cleaner). Get your glasses wet, spray them down, rub the soapy water all around, rinse, dry with a microfiber cloth! Do it once or twice a day and if you didn’t with this pair, next time you buy glasses get them with the anti glare oleophobic and hydrophobic coating
