My sugestion is similar to Rushton's.--Getting rid of the dry dust first---Then Glass Plus is as good as it gets. NO STREAKS.---Spray the soft cotton tee shirt; not the speaker.Turn the rag after doing one side to dry that side---This I find is much better than plain Windex. The tops are the only side where you have to worry about dry dust.You can blow that off with your breath.
What's Best Care for Piano Black Finish Speakers?
Hello- I just got a new pair of speakers in Piano Black finish. They look great. BUT, I know they need SPECIAL care, to prevent SWIRL marks from cleaning. Can anyone give me advice on the type of cloth to use and cleaners and/or polish for them? Thanks.
