Ever since the arrival of the new Rs 2000 notes, there have been a lot of rumours about it. After the rumours of a GPS chip (which the RBI had to deny), there were reports of the new notes running colour when washed. 

This rumour came as a result of multiple videos showing the new notes being washed in liquids ranging from water to a aerated drink. One of the videos shows some colour left over after the note was washed.

But Economic Affairs Secretary Shantikanta Das said that it was normal for the notes to lose some colour when dissolved in liquid.

The senior bureaucrat said that intaglio ink used in notes does run a little when washed and said that if one tried it with an old Rs 100 note as well, some colour would leak. 

“In fact if there’s no colour, it’s a sign of fake currency,” he said.

But despite that it might not be a very good idea to wash your new currency notes. Just saying.
