View Full Version : Best way to remove 2nd anode goo?

05-18-2016, 04:40 PM
I went to the glue the label back on my Zenith Chromacolor's 25VBQP22, and I remembered that I was supposed to get all the goo off the 2nd anode, but I kept forgetting to ask how. So what works best?

Goo Gone?

Acetone or a hydrocarbon solvent like "Goof Off" or lighter fluid should work. The "goo" is silicone grease, most likely...

I'll try the Goo Gone first - I've had good luck with that stuff. If that doesn't work, I'll try Goof Off.

Acetone and a rag should work.
Make sure to test the rag first or you'll dissolve the rag as well.

Be careful with acetone because it will dissolve many types of plastic (including vinyl).

It could be silicone grease, or plasticizers if it has a clear vinyl anode cap. Alcohol, or lighter fluid should clean it up. I recommend coating the under side of the anode cup with some silicone dielectric grease (available at an auto parts store) to avoid arcing when it's humid.

Lighter fluid should work well, just be sure the tube is discharged, sparks and a rag full of lighter fluid is not a good combination.

You will want to avoid getting the solvent onto the external dag coating, as well. It will easily dissolve, and potentially leave conductive residue on the bare area around the anode button.

Thanks for the information. That would be pretty critical.

We always used 91% isopropyl alky & paper towels.

I used the alcohol and the goo just dissolved away. I highly recommend this method.
