Unyellowing wraps - cool method!
Here`s something cool for you wrap restorers.
My friend Larry got to unyellow his Luddyes, and i reckoned i`d help a fellow or two by posting the whole story here.

That could change everything in the vintage world. I have a couple of BDP Slingerlands that will get this treatment if I can ever find the time as I am not a fan of "dull grey diamond pearl."

For the purists out there, I would say if there is a way to restore a wrap to it's original condition, then, by all means do it. Why would you not?

I use Mother's Powerball kit. It's a headlight cleaner/restorer that you can get at any auto parts store. There have been other threads about it here at VDF.

Alright, no one has asked this, but....

When did wraps go from "celluloid pyralin based" (don't know if this stuff works on it?) to PVC, which RetroBrite solution apparently works on ?

There's another title here conc. how to clean dirty felt beaters. I wonder whether the Hydrogen peroxide works well in this application as well? Coffee Break2

Re: Unyellowing wraps - cool method!

Kevins has hit the proverbial nail, squarely on the head here.. and .. I just saw this post now.. ( THANKS Gary! ) .. otherwise I would have commented sooner. That all said...

The KEY here, is EXACTLY what Kevins mentioned: Pyralin vs. PVC... BIG DIFFERENCE!! Many of you may remember that I have lightened vintage WMP with excellent success in the past and have shared my method here and there, although I have always maintained that it is RISKY!! So...

The method discussed here will NOT work on Pyralin/cellulose based wraps/WMP.. because .. the yellowing that takes place on those particular wraps happen from the INSIDE out... not on top. As to how well the stuff mentioned here works on PVC, well... perhaps someone is willing to take up the gauntlet of challenge and check it out. I will say again however... NOT RECOMMENDED on the "older" Pyralin/cellulose film, which in reality, is NOT plastic. PVC is a form of plastic... completely different material. As to WHEN the change to PVC took place, I don't really know. I do know that Pyralin was in place up until at LEAST 1966 though. That might act as a rough guide for anyone so inclined.

Wait a minute! After all the praise everyone has given the Novus products I am planning to go to my nearest Harley Davidson Dealer to purchase some tomorrow and now this. I don't know when or how or even why drum companies changed what their wraps are made of but apparently Novas doesn,t damage "vintage" wraps so I,am going to stick with this tried & proven method.

I,am a retired firefighter and know there are some dangerious chemicals out there. So members should handle any chemicals safely with this new treatment.
