can you use windex or should i use aquarium safe to clean inside of tanks that will hold fish in a month or two? will ammonia dissipate by then or will it stay
There is almost no ammonia in glass cleaner anyway. It contains .05% of a solution that is already only 28% ammonia. Still, hopefully after using Windex you'd give the tank another cleaning with water which would make the question meaningless.
Whatever you use will rinse out. Just make sure to rinse several times. Then once more. As long as it does'nt permeate the silicone. I've had to use CLR before.
