Are these white spots cause for concern?

#RubberPlant I just got this baby rubber plant a few days ago and noticed these white spots. I figured they were marks from fertilizer or something, but after I wiped all the leaves with a moist cloth, I noticed they came right back. I also threw in a picture of the underside of the leaves in case anyone sees an signs of pests that I’m missing.

They look like hard water stains. Maybe try cleaning a leaf with a soft cloth and a spray bottle mix of filtered water and lemon juice and see if that gets the minerals off.
Yeah, it's good to wipe the leaves with a moist towel or napkin from time to time. Ficus also naturally have some spots along the leaf that look like little pimples. Aside from the stains, looks good otherwise!
Thank you guys!!
i had these on a rubber plant i recently bought as well, and they didn’t go away after a wipe down (i only used water and a napkin though), but they don’t seem to affect the plant at all.
