Clean or not? Tamron 35-135

Got this lens in exchage from Jes for some adapters.

It does have fungus and I thought it as repair project.

But: it is a really nice small all round lens.
But #2:
schematics look like this:



it has 15 elements in 13 groups and a separate macro helicoid

but #3:
sample pics with Kodak

I think I'd leave that well alone! The pictures look very good, so why risk a nice lens ?

It may well benefit from professional cleaning to remove fungus. That kind of lens design would be a tricky clean for a DIY I think.
OTOH, it takes dreamy portrait type shots at present.
This can be an advantage when shooting female portraits.
