What is wrong with adding one drop of liquid soap to a cup of water and placing that in a spray bottle? It works for me.
I save the alcohol for when my photos don’t turn out as good as I thought they would. I drink a lot!

Back to 1964 a freshman in the high school Photography club The faculty advisor would often repeat "the last thing you want to do is clean your lens". Only when light shown across the lens reveals actual foreran substance should you risk touching the lens. First use a bulb aspirator purchased in a drug store to try and blow off the substance. (Bulb aspirator was 1/2 the price of what was being sold in the camera stores ). Next would be to brush away the dirt with a soft brush from the makeup counter from the same drug store. As a last resource for something like a greasy fingerprint would be the use of a small peace of paper lens tissue moistened with lens cleaning solution. Generally just water and alcohol. using only enough scrubbing pressure to remove the offending substance. The damp tissue would be followed by a dry tissue and the final blow from the bulb blower. It was then advisable to place a clean clear or UV filter on the clean lens thus preventing the need to touch the lens itself unless absolutely necessary.
Basically while there have been many products available today the principle remains the same The last thing you want to do is clean your lens unless absolutely necessary. Its cheaper to replace a filter then the whole lens.
