Hello All I said OK to an invitation to fix a repeater that suddenly quit after years of trouble free service. Found a critical wire chewed in two and several more "almosts". The fixes were easy but a problem remains in the cleanup.
Rat trash and droppings (OK to read as a common four letter word) swept and vacuumed out easily but the brown "tracking" residue remaining on the base surfaces and trails is resistant to everything I have tried----water, dish and laundry detergents straight and with water, 409, alcohol, "Goo-off" and paint thinner. The crud releases from vinyl wire with a lot of scrubbing using one of the detergents and water but nothing I have tried lifts the crud at all from a painted, galvanized or plated metal surface. What works?---any and all practical suggestions will be tried and their performance reported. Thanks much-- Scott, N6NXI
