Dirty LED headlights inside

[Brammers69]

Afternoon good people, 

This week's problem... I drove through a very deep puddle last week, a lot deeper than I anticipated, if I'd have known I wouldn't have gone through, anyway... I ended up with water in my LED headlights, I've had them out and drained them off, heated them up and got all the moisture out, however the water that got in was mucky water and I've now got dirty lenses inside and not to sure how to go about it, will I need to get the heat gun out and separate the lens cover or can I partially strip them down inside?

That's the way to do it if you can.
