Jeremy I would put that Zeiss product in the bin, NOW.

I’m surprised you aren’t aware there is a thread on CN in which it appears that stuff completely removed the coatings from a Meade ScT corrector, and the contents are not exactly what it seems.

Secondly while multicoatings may be quite tough (as the ones on my specs are) this does not mean all coatings are - as I found out recently - something did completely remove the coatings on my latest pair and I had to go back to using the previous pair.

In particular, Takahashi warn cleaning agents containing ammonia will damage their coatings.
