Sziasztok!
Van nálam egy régi rádió-erősítő javításon.
A belseje tele volt porral, kifújattam.
Viszont valószínűleg párát is kaphatott mert a panel alkatrészoldalán több helyen a por nagyon belekötött.
Alkoholt nem szeretnék elpazarolni a kimosására.
Olyan helyeken is van kosz, ahol mechanikusan elég nehezen hozzáférhető.
Mivel szoktátok fellazítani és eltávolítani az ilyen jellegű szennyeződéseket?
Üdv.: Kumi
