Goop Alert!

Clean Up on Aisle Five! (click on the bottom photo in the ad)
They look to be in nice shape other than the goop--would a blow dryer and a rag clean up that mess?

I've never done it, but I think I'd try an Exacto knife and solvent of some kind. My fear would be that without mechanical removal of the majority of the stuff that it make simply spread and make a bigger mess.

A blow dryer will soften the compound enough to allow removal of the driver from the cabinet without damage.

The blow dryer may or may not thin the compound enough to allow redistribution.

If it can't be done with heat, my favorite solvent(as suggested by other members) is MEK(methyl ethyl ketone).

MEK needs to be used with much caution and plenty of ventilation, inhalation of the concentrated vapors causes ketosis of the lungs, and the vapors in concentration can ignite explosively.

MEK is the main and active ingredient in most PVC pipe solvent/cleaner.

I had a similar situation with my Valencias. I called Bill at GPA who told me this is a common problem. He advised me to use acetone and a small brush to remove the goop. I used a soldering acid brush. He also advised me to rotate the 416's 180 degrees from time to time to keep this from happening again.

The material did not come off easily but with persistance it did come off. I also used the acitone to clean and refresh the surrounds all the way around the cone. Now they look brand new.

The acetone can be bought at Lowes as well as the brushes. It was not such a big deal to remove the goop and also refresh my 416's.

Good to know--thanks everyone. Now if I ever have goop dripping on any of my woofers I'll know how to handle it. So far I've been lucky, and never had any problems in that regard. Of course gravity is a factor but I'm guessing it's too many 90 (plus) degree days (fahrenheit) that causes the goop to run like that......

I have never seen the goop droop like that.
I see it in many ads on Ebay.
Especially on 419-8C biflex woofs.
What is the story here. No one has AC? I don't either, but it doesn't get all that hot in OR.
What gives?
I have 879-8B Santanas...they are pristine! No Goop droop. 904-8A, no goop droop. 411's, 416-8A, and -8B, and -8C no goop droop.

I think the amount of goop droop you have depends on who was administering the goop in the first place.

Also you might want to try Butyl Cellosolve as your thinner.
