Scraping stickers is very simple. For example, go to your inventory, select the weapon with the sticker, then just click on ‘Scrape Stickers’ in the menu, and you’ll enter the corresponding mode.
Select the desired sticker on your weapon if there are multiple. Then, click on the ‘Scrape Stickers’ button until it disappears if you want to remove the sticker completely. Be careful, as once you start scraping, the sticker cannot be restored.
You need to repeat the procedure 10 times, after which you will see a corresponding window warning you about the sticker’s removal.
An interesting observation: some stickers have secrets under the first layer and can reveal themselves anew, acquiring a unique appearance hidden by their creator.
For example, if you scrape the ‘Call Your Flashes’ sticker, at the final stage, you will see an image of a player blinded by a flashbang with the caption ‘Your Teammates.’ There are plenty of such stickers in the game, so pay attention—you might reconsider completely removing the sticker.
