[Hallicrafters] """"grimy rig

[Carl]

There are so many different cleaning products, regional and national, and so 
many different metals and alloys that one product does not work for all. Try 
them all.

For decades Ive been promoting Scrubbing Bubbles for grime and nicotine 
removal.

Murphys is great on wood cabinets.

Greased Lightning does wonders on serious crud buildups as well as restoring 
plated chassis such as some Hammarlunds.

Prep-Step in various concentrations gently loosens rust with Q-Tips or a rag 
and doesnt attack good metal.

Diet Pepsi and Coke is another good rust remover, especially on tiny chrome 
pits since it contains phosphoric acid. Regular Coke and Pepsi contains 
sugar and should be avoided in many cases as the residue gets where it cant 
be removed at times.

Ive dunked chassis that were completely stripped of anything non ferric in 
sulphated molasses and water and let sit a week or so. Non sealed 
transformers and chokes must be removed. Summer temperatures work faster and 
do it outside as it can raise a stink. Use 1 part sulphated molasses to 4 or 
5 parts of water. It will not remove grease and paint. Remove and pressure 
rinse the scale with a garden hose and the remains is pure virgin steel and 
iron. Protect immediately with a quick drying sealer to prevent flash rust, 
I use the Prep-Step. Many use a non yellowing clear coat or alodine.  The 
"broth" may be reused until its too weak and then diluted and poured in the 
garden wherever iron loving plants are. It also kills moss.
Its no joke or urban myth, farmers have been using it for centuries and Ive 
used it even for cleaning engine blocks, it leaves badly rust scaled water 
passages looking new.

It also works well on pot metal, and carburetor castings but just do quick 
dunks until the job is done and rinse quickly. Leave it alone for a week and 
it will be dissolved!
.

WD-40 and similar will collect dirt in no time if not completely removed.
