Hi again
If you have taken the mirror out it is probably OK to give it a clean whilst apart but be very careful in how you do it and as stated follow those instructions in IIS projects and articles.Only wipe with gentle strokes and don't rub at all. Only apply as much pressure as the weight of the water on the cotton balls.
Only use a couple of drops of dishwashing detergent and make sure you don't let let your mirror dry before rinsing and flushing with distilled water as any traces of detergent will leave a smear on your mirror. Let dry naturally without trying to touch the surface of the mirror. If there are any smears left, it is probably best left alone.
Hope this helps and after taking your mirror apart and reinstalling you will now have to collimate your scope but that's another project that you have to do or you may already know how to do.
Good luck and be very careful!!!!
Cheers Rick
