You're not just looking for scents or colors. You need to check for surfactants.
Real "hardware" stores like Ace & True Value will usually have pure ammonia without surfactants. I've heard Walmart even has pure ammonia, but they've always been out of it when I thought to check the labels there.
"Home Improvement" stores like Home Depot and Lowes usually carry the smelly/soapy stuff.
If the only ingredient listed is ammonium hydroxide, it should be the right stuff.
If you don't have any fish in the tank, you don't need to do a water change until the cycle is complete, unless you accidentally dose the ammonia up too high (overdosing ammonia can stall the cycling process). It can however be beneficial to do a few W/C's when the nitrAte starts rising, so that it's not at an insane level by the time you plan to put the fish in, causing you to scramble to do a ton of changes at the last minute.
