Mould on inside of ST80 objective lens

[Pixies]

Hi,

The little old ST80 sits on a tripod in the corner of the kitchen, ready to be rolled-out as my quick grab-and-go. Perhaps I don't look after it as much as its big Japanese brothers - upstairs in the study in carry cases with their desiccant bags. And so I've just noticed 2 small patches of mould on the objective.

I've just removed the objective cell and it's resting in the sunshine outside, trying to halt any further growth.

As it's an ST80, it's quite straightforward to disassemble the objectives. I was planning on blackening the edges anyway. So what do SGLers recommend for cleaning the mould off? A google search comes back with lots of different methods/products. I have Baader Wonder Fluid but can pop round the corner to the chemist for anything more exotic.

Thanks

I would guess Baader fluid to clean up the bulk and another healthy dose of the sun's finest ultraviolet to put an end to the mould's miserable life 😂
