earlier today I removed the diffuser, i cleaned and washed it.
I forgot to take a picture of the "before" but it was just that ridiculously ugly grey color and I have since put one coat of plastidip on and so far it looks better than the grille, I believe this is partially due to the even lines of the diffuser compared to the grille. So far I like the outcome. I will post pictures later today!
