I bought 2 Frantz (Toilet Paper Element) Oil Filters and I found yellow orange residue under the Screens.

Also the Filter was setup with larger Hoses then would be needed for use and an Oil Filter.

I am guessing it was being used to Filter WVO but have never seen any of that before. So I am asking if someone can identify the Residue/Coating.

Yep. WVO, exposed to air, will turn to a plastic resin, or gum.
It will resist most chemical agent attempts at removal. It must be removed physically.
It's a messy business.

The good news.....it is great substance to patch holes with on your roof

At least someone had enough sense to filter the WVO.

If he did not filter the stuff in stages I am guessing the Frantz Filter plugged up really fast as the top of a Tiolet Paper Roll does not have a lot of surface area to it.

Bad news if that stuff does that in Your Fuel System.

Oddly the rest of the Filter was clean.

I put the cleaner of the two Frantz Oil Filters on My Car and did not change the Oil just to see if it made any visable change in the Oil. And, yes the Oil is still Black.

This is too subjective to be a test but after installing the Frantz Oil Filter the Oil on the Dip Stick looked less thick and just a tiny bit ligher colored but nothing I could say for certain.

I was thinking about trying a heat shrink gun to liquify the WVO crud off some parts I have on the bench.

Maybe Aluminum is one of the Things WVO does not stick to well as Paint will also not adhere to Aluminum well.

Also since the rest of the Filter is clean maybe He found something to soak it in that loosend the stuff. The Suff was under 2 Screens that slid over the central Tube and there was a sheetmetal part with Rubber attached (the Rubber is mush) that held the screnes inplace so it looks like the PO never removed the Screnes to clean it.

It takes air exposure for the WVO to polymerize. So the rest of the filter was full of oil.

If you want to believe it is WVO then it is WVO. You can think they are 'may be' anything. You are trying to fit a question to a preconceived answer.

that doesn't look like polymerized vo, the stuff on the edge of the filter housing looks more like polymerized vo than your pic.
I agree above that you wouldn't be peeling off any polymerization like that, no way. The fact that you can peel it off like that at all means its very likely not VO.

VO polymerizes worst on steel, second worst on aluminum, and very minor on plastics.

That looks to me like a remnant from a glued together filter, or even some sort of gasket maker that just happens to be a similar VO color.

Returning to polymerized VO, of course you have seen it, any time you've left oil in a pan and it turned to sticky jelly. Same principle.

As for cleaning products, the whole idea that VO needs some miraculous caustic chemical to remove it is bunk, any household degreaser and soaking will take it off. Anything that you use to clean pots and pans, because thats what it is, a cooking mess.

Awhile back I put a new valve cover gasket on my aunt's motorcycle and the oil that had dripped out and cooked on the engine is exactly what that looks like. It was also easy to remove by scraping or with lacquer thinner in the harder to get areas. It's bendy and stretchy like rubber, right? I'm betting that's what it is. Who knows how it got there though.

This is what polymerized VO looks like.

feels: rubery, sticky

Easy to peel off the steel filter housings this was stuck to

I'm in process at the moment of testing multiple substances that have been mentioned, abbility to desolve polymerized VO.

Stay tuned for results...

I have some dried grease on the bottom pan of my in-garage refinery and it looks similar. I will try to remember to take a snappy or two. I do know that dried or semi-dried WVO is some nasty stuff to remove. I found hot grease will remove dried up grease or soaking in gas or letting it soak in the real Berryman's Chem Dip (5 gallon pal) to get the really nasty, industrial cleaning effect. If you get this stuff, keep it outdoors. It smells horrible.
