A.5 Cleaning The Soldered Joint
Vigorous scrubbing with a wire brush and steel wool will remove torch black with good
results. In addition, cleaning with an acid solution can make this job easier. The
procedure is as follows:
!
WARNING:
MURIATIC ACID USED IN THE FOLLOWING PROCEDURE IS HAZARDOUS. USE
EYE AND SKIN PROTECTION WHEN HANDLING OR MIXING. KEEP AN EXTRA BOX
OF BAKING SODA HANDY FOR FIRST AID OR TO NEUTRALIZE SPILLS. PERFORM
THE PROCEDURES OUTDOORS IF POSSIBLE. IF THE WORK MUST BE DONE
INDOORS, WORK ONLY IN WELL VENTILATED AREA.
!
WARNING:
IN THE FOLLOWING MIXING PROCEDURE, ALWAYS PUT WATER IN THE CON-
TAINER FIRST AND THEN ADD ACID TO THE WATER. ADDING WATER TO A CON-
TAINER OF ACID MAY RESULT IN A VIOLENT & DANGEROUS REACTION.
a.
Prepare three plastic 5 gallon buckets as follows:
1.
Bucket #1 - Water
2.
Bucket #2 - One quart muriatic acid in four gallons of water (SEE WARN-
INGS ABOVE)
3.
Bucket #3 - One pound baking soda in five gallons of water
b.
After soldering is finished, dip the end of the line in the water to cool.
c.
Set the cooled end of the line into the acid-water mixture for 5-10 minutes. This
will loosen the film and brighten the silver.
d.
Immerse the end of the line into the soda solution. This will stop the action of the
acid.
e.
Use a Scotch Bright pad or steel wool to scrub off the remaining torch black.

If the flux scale is particularly stubborn repeat the process.
