[R-390] Rat Track Solvent?

[Cecil Acuff]

If Gumout Carb Cleaner won't touch it I don't know what will...

I wouldn't use on painted surfaces though....or at least try it in a small out of the way spot to see if it is going to soften the paint.

Only other thing I have used as well is good old lacquer thinner.

Both of the above are flammable and require they be used in well ventilated areas so be careful....

Another serious concern is to wear a mask when removing rat droppings.  Hanta virus is a serious thing.  (Probably spelled it wrong?)

  Hello All----

  A while back, I remember conciderable disscussion on various cleaning materials for various problems and places in the 390. I'm not doing a 390 just now (three to go) but the solution to my present problem might be useful in sombody's 390 restoration.

  Recently, I said OK to a request to fix a repeater that suddenly quit after years of trouble free service. I 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 of the rack easily but the brown "tracking" residue remaining on the base surfaces and apparent rat 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, bare, galvanized or plated metal surface.

  What works?---any and all practical suggestions will be tried and their performance reported and I apologize for stretching the 390 boundry a bit.

  Thanks much--

  Scott, N6NXI
