Phalaenopsis how do you clean your leaves

[Arizona Jeanie]

Pre-covid I entered an Echeveria in our county fair. The leaves had a lot of spots from hard water, so I cleaned each leaf with a q-tip dipped in mayonnaise. It worked great, left the leaves clean and shiny and didn't seem to harm the plant. I only did this once, and rinsed it well when I was done. Won a well-deserved second place ribbon
I've never tried it on a Phal, I just rinse off the leaves at the sink and don't worry about shiny.
