Cleaning speaker cones

[oldslapper]

Cleaning a recently acquired used PJ Briefcase, I noticed behind the grill was a bit grubby. Took the grill off and the driver cones are covered in dried mud.!
Any ideas on how to clean it off? Whilst I'm happy with the sound of the combo, I don't think mud on the speakers is "helpful".

Ta,

I wouldn't be sure that's dried mud...
Lots of cones are treated with strange compounds

Turn all dials to max and hit the lowest note that you have... that should shift any loose dust/dirt/mud!

Alternatively if your vacuum cleaner has a variable power setting (or an adjustable hole in the vacuum tube) set it to low (open) and with the brush adapter fitted lightly brush the cone; test it on something like your sofa first just so that you gauge the power of the vacuum.

Clean them with a damp rag. So long as you don't soak the cones they won't be bothered.

Thanks guys, I'll give all the suggestions a go.

Had worried about damp cloth Bill, but that's reassuring.

Congratulations on purchasing a cab that can produce brown notes!

Sound a bit 'muddy' does it?
