Hello,

I almost came to the conclusion that it's time to try and let the 4311B go, I bought them as a teen and still own since then (which is quite a long time), I gave the grills to a carpenter to be redone (they were quite cheap and prone to break) but both got lost and the suspensions collected dust which make they seem dirty/damaged which is not the case so I'd like to ask for your advise on how to clean them so I can take pictures and put them on sale even tho I doubt anybody will come and pick them up living in a hard to reach place.

Any suggestion is welcome

Grazie
