Must one remove stickers from the vessels?
Normally removed stickers: All stickers that are normally removed from the vessel must be removed prior to immersion due to it being a Chatzitza. When removing these stickers one must also remove any leftover sticker glue which remains attached to the vessel.
Stickers meant to remain on vessel: If the sticker is meant to remain on the vessel, such as stickers which tell instructions or warning stickers, it is not considered an interval and is not required to be removed. The same applies for any sticker that for whatever reason is generally left on the vessel.
