A Bad Experience Cleaning Equipment

Was cleaning my SCT corrector with a mixture of 1/4 rubbing alchohol, 1/4 vinigar, and 1/2 di water. Vinigar was my wifes idea (maybe a real bad idea, but I did it anyway). Anyway, she put it in an unmarked seltzer bottle, and...yes...I came in from yard work, poured a tall glass of it, and "threw it down the hatch"....horrible horrible taste.

Confuse-us say: "Man who clean corrector with vinegar end up with SCT that smell like pickle."

I did that once with a glass of kerosine. Very unpleasant.

I prefer Purosol. Great for eyepieces, mirrors, what have you. I've used windex too.

Purosol is sold at a wide variety of places, including Astro-Physics. This is one:

There is a complete "How to Clean Your Corrector Plate" tutorial on file at Yahoo! C14 group and also Yahoo! sct-user.
Includes pics and some appendices on other items related to performance.

It is the most streak-free results I've gotten of the various things I have tried on my optics. Incidentally Texas Nautical Repair uses kerosene!
