I would purchase an industrial strength pressure washer (Min 900 PSI) fill it with javex and spray the affected area for approximately 45 minutes. You may want to clean the speaker in a well ventilated area as the smell of ammonia can be overpowering
Spilled marinara sauce on wood speaker....
I just spilled a heavy red sauce on my solid wood speakers, i tried the red wine theory but after 3 glasses of pinot noir I can still see it. I was told Red wine gets out stains Any suggestions? HELP, it is drying out! FWIW, they sound even better and btw they are 2 way floorstanders. Should i try a cabernet?...
