Found this post on cloudy nights, Not sure of the chemistry involved looks like a bit of serendipity . Anyway here it is:
"This is what I did for the corrector on an old 10" Meade LX3 our club got to remove the coating.
1) I cleaned it good with Dawn dish washing liquid and a soft cloth. Rinsed with distilled water and dried it.
2) I then soaked it several days in Ferric Chloride (This is printed circuit board etching solution you can buy it at Radio Shack). I would go and agitate it every few hours. I replaced the Ferric Chloride after the first day.
3) Rinsed well with distilled water.
4) I then soaked it in muriatic acid (purchased at Home Depot) for about 15-20 minutes and kept agitating it. I took it out several times and rinsed it to check the progress.
5) Rinsed well with distilled water.
6) Let it soak in a solution of baking soda and water to neutralize any remaining acid.
7) I cleaned it again with Dawn dish washing liquid and cotton balls. Rinsed with distilled water and dried it.
I used a shallow plastic tub with a snap on lid, some rubber gloves and a plastic funnel.
I did not get it recoated, I just installed it as is and it works well. I believe the cost for recoating was around $125 per side."
Hope this helps philip * *
