[ARC5] [Milsurplus] Cleaning fine crackle paint

[Bill Carns]

I will tell you what I use and you will be amazed at how the dirt literally
jumps right off and out of the wrinkle.  Mix a solution of 50 % 409 right
from the bottle and 50% household ammonia (buy at grocery story) have a
medium soft brush ready. Spray the solution liberally on the wrinkle paint
all over. Quickly give it a general liberal liquid good brushing and then
watch.  The 409/Ammonia will foam up and it will be white at first. When the
foam gets dirty, you are done. It does not take long....  like a minute or
less.  Give it a good rinse in tap water and then apply a dilute solution of
very dilute warm water and dishwasher liquid soap.  This has a anti spotting
agent in it that makes the surface of your piece reject water when drying.
Then rinse with DI water really well.  The two good rinses after the ammonia
exposure are necessary to preclude future corrosion.

Now blow dry and keep it warm for a while.  

Now, you may still have some spots where the paint has a white cast.
Liberally apply WD-40 to the entire piece, and then take off the remainder
with a soft dry towel. Let the piece stand for a day and you will have a
super clean, rejuvenated paint job if the paint was decent at all to start
with.....and no more white.

I have been using this treatment for restoration of 25 years and am
currently using radios that I did this to 20 plus years ago and they look as
good as they did when I finished them.

It works.  Be very careful of anything that has silicone in it.  Amour All -
for instance - is long term death on paint and if you ever want to do any
recoating later, you do not want silicone anywhere near your radio.  It is
also long term death on Vinyl - although the Amour All folks would have you
cleaning your dash with it every day...  Looks good for a while and kills
the vinyl long term.

I'm sure this has been covered but probably long ago... What are some good
techniques for cleaning old, fine dirt & dust from fine grained black
crackle paint? I've tried dish soap, warm water & toothbrush but it seems
every time it the paint dries there is still light colored dirt in the
crackles.

Thanks & 73,
