Does anyone know how to remove annoying stickers that get stuck on the outside of the passort? I don't mean VISA's on pages in the passport, I mean stickers that customs, embassies, security, airline luggage tags stick on the outside of your passport. Things like embassy barcodes to track your passport during a VISA application, things like the colour sticker stuck on the back of your passport used by some aiports when going through security, etc. The back of my passport is full of ugly useless stickers and sticker glue, would like to remove them without damaging my passport. Any ideas on how to do that? Thanks!
