JBL L150 LPAD & Crossover Cleaning Questions

So I decided to try and clean an LPAD that just wouldn't respond to a whole lot of deoxit squirted from the outside, it would still cut out altogether sometimes or would only turn on very low, so I got it out and took off the cover:

Looks pretty clean to me. I must've got enough in there, what can it be. there's 2 contacts points, here's one with a little green on the end:

Maybe I need to clean under here, but now that I'm this far, what should I do to clean that, like a point file or?

More green stuff here, how should I clean that off?

Under here was a piece of foam that will disintegrate if I should even bend it, I'm going to replace it with a couple of foam strips, but a lot of these silver contacts have like a leeched foam on them should I attempt to clean that or just leave it?

Bad Tweeter

Damn it's the tweeter, swapped em and sure enough.

This tweeter just cuts out intermittently and mostly now it's sort of half the volume of all my 033's. (got 4 of em) Funny it's failing this way. Any suggestions, take the diaphragm all the way out and check for maybe cold solder, or do the voice coils end up doing this?

Anyone tried the replacements from Midwest Speaker:

P.S. Hope this doesn't get moved from the ebay link, I just want opinions, thanks.
