How would I remove stickers that are hard to remove? I'v tried the scrape
rite and it leves too much adhesive for stickers that are hard to remove.
The ones that are easier they don't leve too much adhesive.

The scrape rite razor is only $.075, but I think it's absolutely useless, except for on the stickers that come with an Eastsheen 4x4x4 or 5x5x5. If you're removing the stickers that come with a standard Rubik's Cube (ie: 25th Anniversary Edition), you're better off just using a knife, lifting up one of the edges, and peeling off slowly, then using the sticker to dab off the remaining adhesive.

I use a pocket knife and Goo Gone, which is a completely harmless adhesive remover.

I started using Goo Gone, but found (after a suggestion by Cubesmith) that rubbing alcohol worked just about as well and didn't need a soap and water clean up afterwards.

I think the plastic razor works great on Rubiks 3x3x3's. It's all about the angle you attack the corner with. I am very pleased with mine.

Now that I've gotten offtopic, I have no added information again about the OP. Sorry

I tried rubbing alcohol once to no avail...then again maybe I wasn't doing it properly...?

Would you apply the rubbing alcohol with the sticker on or with it removed to
remove the adhesive?

i know this may sound like overkill, but use a hairdrier on high heat. Get really close to the stickers with it, obviously not touching, but they should be quite warm when you stop the hairdrier. Go over the pieces for about thirty seconds, and it will heat up the adhesive making it easier to remove, while also reducing the sticky residue. With a normal rubik's brand cube, i can remove every sticker, by hand in about 5 minutes with absolutely no residue whatsoever. Try it, it really works. IF there is any leftover residue however, just a splash of alcohol or googone and it will be fine.

Would ethnol work? Is there an optimal consintration percentage for rubbing
alcohol? I don't want to dissolve my cube.

Sorry, I would remove the stickers first. I use the scrape rite I bought from Cubesmith. I have to say, however, it dulled up really quickly. Any stray bump against the edge of a cubie and it has a ding. It isn't hard to smooth them out, but the edge is never as good as when it was new. At .75 each, I'm just going to get a bunch next order.

Does anyone else who uses a scrape rite wish it was sharp on just one side? My finger got quite sore from pushing on the sharp back edge when taking off stickers. Some were easy, but perhaps I should have been using the hair dryer technique on the tough ones.

As for concentrations, I just went to the medical isle of the local grocery store and got what they had, which I believe was 91%. Just wet a paper towel (don't be stingy) and the some pressure and time. If the thing is really gooey you may want to use many soaked towel bits to wipe off the disolved stickum. I don't think alcohol will damage the plastic (mine have been fine) although something like goo gone might if given enough time.

Thanks for the info I use scrape rite and mine dull quickly too i just pick up
a new one because they are pretty cheap. when I was trying to remove the
stickers off the cheap square-1 I sometimes peeled a layer of skin off my
thumb (the stickers were super hard to remove).

I just restickered my modified Square-1 (now called "Square-2") and the stickers weren't easy to get off. If the Scrape rite dulls, just scrape it backwards against a hard surface (table top, for instance) to get an edge back. It isn't as good as the original, but my single scrape rite has lasted through the Square-1 and two other cubes, one with some really sticky orange stickers.

Apparently a rubber/eraser is good for getting rid of the adhesive.

Anyone confirm this?

I used to remove the adhesive on Post Its with an eraser. It really depends on the
eraser.
