I just bought a can of wipes that are specifically for aquarium use, it says it is safe to clean both inside & outsides of aquariums, I don't have it with me here at work, but it seem much more convenient than the water down & then dry method with RO water.. I found them at *****, I haven't tried them yet. Anyone try these? The do have ammonia-free glass cleaner too, still wouldn't spray within viscinity of the tank though... :joy:
