Vanda Bangkok Sunset spots and blotches on leaves

[naturalistSean]

I've been neglecting my Vanda Bangkok Sunset. It has been outside but with the nights getting cold I would like to bring it back in. Naturally I would like to be sure it is disease free when I do this so that it doesn't impact my other orchids.
Sadly it has developed these spots and blotches. I'm worried that this could be bacterial in nature. What are your thoughts? Diseased? mere neglect without disease? safe to bring inside?

Thanks in advance for your ideas on this!

Looks like normal wear a tear to me... I'd just give it a good close look in all the little hiding spots to make sure there is no scale or mealy bugs before you bring it in

the purple spots means you are getting plenty of light.

the scars are from being bumped around and bruised.

the yellow leaves on the bottom have done their job and do start to fail.

55f/13c or below they don't like so bring it in to keep the roots healthy.

good luck
