I use a soft paintbrush, 2-3" wide.

Put it outside durning a big thunderstorm. I do this with all my house plants. It really perks them up.

I usually add a bit of rubbing alchol say half capful to about six cups of water then just one drop of dish detergent. I then use a soft cloth to wipe them off. This gets them clean and also any little nasty bugs would also be removed. But that's just me. :) Velleta

Use a paper towel soaked in milk and squeezed out. Or lemon water.

I clean my leaves with lemon water before shows. Otherwise I just use water and a paper towel.

Never tried, but others use mayo to add a great shine.

Yeah, dont do that. It will smother the plant and hinder proper living processes.

I show my orchids. Before entering them in a show, I wipe all the leaves with skim milk. Shines them up. Has never bothered them.

Learned that from an old-timer.

Otherwise, just wipe them off with water or give them a shower.
