It cleans glass. It contains ammonia. It works as good as other products. Is there more to say? I use it on counters and the stove also. Check the cleaning instructions on your appliance and counters for recommended cleaning products before using. My only complaint, there isn’t a refill bottle available. The spray bottle seems to be the only way ALDI sells this. However at 89 cents per spray bottle, it’s less expensive than using most other brands’ refill bottles.
