Hi, I use a product called Wipeout made by Zoo med. You may have to order right from them if you want it, seems to be abit a hard to find these days. When I got mine I got the guy at the reptile shop to order me a big jug of it. If this is the product Jason was thinking about they do say on the bottle to spray on the glass let sit for ten minutes then wipe clean with paper towel and your good to go. Even though it says you don't need to rinse it out I still rinse it a few times with hot water just to make sure. My frogs have had no ill effects from it. Some others use a vinegar and water solution or even a bleach and water mix but I'm not sure what the ratios would be to mix them since I don't use this method. Maybe someone else that does the vinegar and water or bleach and water will chime in and let you know the ratios.
