Mayonnaise for shiny leaves

[Silje]

I got a lot lime in my water and although I rinse with RO water, my plant still got lime deposits on the leaves that I need to clean off now and then. Mayonnaise works well, I've discovered, but...

Some of the plant that has been exposed to a lot of lime get very persistent spots that can be difficult to remove.

Normally, I just rub the leaves gently with a cloth dipped in mayo and rinse them immediately afterwards, but my question is"

Can I leave the mayo standing on the leaves for some time to let it etch away more of the lime, or will the plant take damage from it?
