# Stubborn water stains or mildew? I bought this huge gorgeous Hoya…

_Posted by Bo on 2026-08-07_

Stubborn water stains or mildew? I bought this huge gorgeous Hoya (Reef Rider) yesterday who was very dusty from a local Mennonite-owned nursery. I rinsed her off in the shower and wiped down her leaves but these stains are still here. Should I treat her for mildew to be safe? When I wiped more aggressively some of it came off.

Looks like water stains to me. I get the same thing. Use distilled water with some lemon juice to wipe them down. It works a little better. 1 part lemon juice to 3-4 parts water
