OK - I knew the big brown truck would be bringing 5 new clear 10/22 factory magazines to my door today.
Yesterday, I stopped by the local fabric shop to pick up some Royal Blue RIT powder dye. The copyright on the box is 2011 - the date stamp inside the box says 03. (so it's the new stuff)
Tonight I took the mags apart and cleaned them in hot water with Dawn Ultra dish washing soap - they were squeaky clean.
I followed the directions above - boiled water - added dye & salt - added mag parts - lowered the heat to just below boiling - kept stirring for about 9 minutes.
The color took almost immediately - I was getting nervous it was getting too dark! I fished the parts out and let them dry/cool on a paper towel. They looked a little foggy when they dried, but a quick rinse took that away and left nice, shiny, deep blue magazines! SUCCESS!!!!
As I was starting to put them back together, my daughter said she would like some purple ones... time to place another order.
Many thanks to all that posted to these threads.
Have a good weekend,
