Notes and Changes:

Compatibility of First Contact and Common Solvents:
The clear and red polymer solvents and their thinners ARE NOT compatible, do not mix them together in wet or dry form.
Isopropanol and Methanol ARE NOT compatible with first contact, do not mix them in wet OR dry form.
Acetone IS compatible with first contact and can be used to clean up dry FC or FC brushes.

Alignment layer:
As of 01/15/14 optics will not be shipped to the sites with an alignment layer in place. The alignment layer section of this E1300017-v3, Sec. 5, will still be included for now for operators who have received optics prior to 01/15/14. Refer to LIGO-E1300142: DCN, General Optics Cleaning Procedure for full details.
