No need respray. That time I call gain city to do chemical cleaning of my air con they use the chemical to clean my cover and become like new. Cos I smoke in the room and the tar turn the air con cover into yellowish. So you want when doing chemical cleaning ask them clean the cover. If not can also try those DIY chemical cleaning kit from home fix. But dunno will remove the stains cos the chemical in those DIY kit is quite dilute. Those use by gain city very strong. When they dilute the chemical I can see fumes like acid....Lol
