Hi all, Need a bit of help/tips on how to remove the sticky residue from stickers off of coin slabs without hurting the slab and coin inside. I recently purchased a coin from a seller who placed a sticker blocking a good portion of the reverse of the coin -- when I tried to remove it lo and behold there was a thin film of the sticky stuff stuck on the slab! Any help is appreciated! -CB
I had a sticker on one of my slabs and a damp paper towel was able to get rid of most of the sticker residue.
Goo Gone works well, but keep it way from the seam or any cracks in the slab. Capillary action can draw it inside the slab.
I've had pretty good luck using WD40 on mastic that Goo Gone wouldn't remove completely. The same warnings apply about it getting near the cracks.
Another product is called PrepSol. I used it to remove cheap adhesive back trim off a car of mine. No effects to the paint so I imagine its safe for plastics as well.
Not odd, it's the oil in the peanut butter that is dissolving the adhesive, same as with the goo gone or wd-40. You will find that most any light weight oil will work.
Thanks for all the help! The only reason I'm afraid to use any of those products is because it might affect/react with the coin inside in the long run. I think I'll try the damp paper towel first and then some WD40.
I'm going pick up some Goo Gone. I have used WD40 it works great, but with the warnings about long term harmful vapors. Anyone compared the two and have an opinion on which is better?
A little soap and water works. What's the deal with the common practice of putting a sticker over the back hologram label which flakes it apart when you remove the sticker? It looks shoddy to see a $10,000 coin (not that I have one) in a slab with the back hologram all chunked off...
There are no warnings about long term harmful vapors for WD40. It is basically kerosene with a bit of fish oil. Nothing going to arm you in any normal quantities. And I looked at the MSDS to be sure.
Well that's good to know, but I was talking about harmful vapors for the coins. I actually hadn't even considered my own health. You see how nutty this hobby makes us, LOL.
I tried non-acetone nail polish removal on an ANACS slab a while back and it reacted with the plastic and clouded it up. Then I polished it with Turtle Wax and it came out fine. Just be careful with any kind of aggressive chemical.
Well I tried WD40 and Goo Gone tonight on 4 coins that arrived today. These are NGC no-line fatties, so these slabs and stickers are OLD. First off, both WD40 and Goo Gone work fine on newer labels that have a clear or white-ish adhesive, and scrubbing a little with q-tips makes fast work of them. Unfortunately for me, 3 of the 4 coins had 20 year old sticker adhesive on both sides, which has turned crusty and yellow. Basically looks like (is?) petrified masking tape! Neither WD40 or Goo Gone worked well on these. I scrubbed, I soaked, I cleaned it up, and repeated. I used my fingernails between sessions. Each coin took about 4 soaks, and I still don't have all this rock-hard yellow adhesive off. Got most, but unless I want to sand blast these fatties, the rest is there to stay. Following the Goo Gone instructions, I dabbled a rag in some soapy water and gave the slab a little cleanup, I hope this takes away most of any remnant liquid and odor. Here is one of the coins I cleaned up:
Very Nice '44 Half. I use some Goo Gone and seems to work fine on all the rattlers I have. I also use Slab Renew, I guess I should just use the Turtle wax, does great on the car! Next one I'll try the WD-40. Thanks for the tips.
