Hi,

I just received this evening a note from the factory of Channel Master dishes (now Skyware Global) in North Carolina, USA.

This note explains how to take care of your aged Channel Master dish. You can either clean it or repaint it, according to the need.


Here it is:


Recommended procedure to re-paint Skyware Global SMC/TMC Reflectors


Cleaning Process:
The cleaning process will depend on the degree of contamination. It includes the following materials:
. Chlorine Bleach (Clorox or equivalent)
. TSP-PF All Purpose Heavy Duty Cleaner (Savorgran or Equivalent)
. Rubber gloves
. Heavy duty sponges
. Soft bristled brush
. Bucket
. Hose or source of water


Mildew and dirt removal:
. Remove by washing with a solution of 1⁄2 cup of TSP-PF dissolved in 3 quarts of warm water and add 1 quart of chlorine bleach. Use solution to scrub area thoroughly using brush or sponges.
. For uniform results, treat entire area not just contaminated area. The bleach should kill the fungus growth and remove stains. TSP-PF removes dirt and grime and wets the surface so that the bleach can work.
. If stains remain, use second application.
. When mildew is gone, rinse thoroughly with clean, warm water and dry surface
completely if painting is required.
. The solution will NOT prevent mildew growth.


Repaint process:
. Scuff the face of the dish lightly with an abrasive pad or sandpaper to improve adhesion.
. Mask the printed logo or scuff it to paint over it. A new logo can be applied over the painted logo.
. If removing a stick-on logo, adhesive residue may remain. Try cleaning with mild solvent such as isopropyl alcohol before re-painting.
. Wipe the face of the dish with a dry rag to remove dust.
. Apply an even coat 1.0-1.5 mils (.0010-.0015 inch, .025-.040mm) of water-based
acrylic paint to the reflector.
. Allow to cure.
. Apply a second even coat 1.0-1.5 mils if necessary.


Notes:
. The choice of color is up to the user.
. Skyware standard light gray color is PMS 428C
. This process is not for hydrophobic coated reflectors
. Be careful not to remove the existing surface finish, only scuff lightly and clean
thoroughly.
. The procedure can be used to paint the back of reflectors as well. In this case there
is no existing finish to consider.


Good luck,

Incidentally, my dishes are different shades of grey (or gray). The Andrew one is clearly darker grey than the Channel Master. Could be due to weathering, of course, one's probably a bit older than the other. Hard to tell mfg date on these things...
