Removing Methylene Blue Stains

007

Last week, a few of my Y9s managed to stain the desks with methylene blue. A chance spillage led to a discovery. I had some Dettol in a beaker to put their discarded cotton buds in and some of this spilt next to the methylene blue stain, I used a cloth to wipe up the spillage and when it came into contact with the methylene blue stain it removed all traces of it from the desk.
It was a very pleasing moment.:D
 
Thank you for this. I had a teacher put methylene blue in her pocket(!). It leaked and I put her labcoat in with all the others to wash so I now have a range of blueish lab coats.
 
A useful tip for methylene blue or Eosin on clothes is to put it in a live yeast solution overnight. It does not have to be strong but just dunk the pocket affected in a beaker of say 1% yeast. Methylene blue and Eosin are used as stains for viability in the brewing industry and go colourless when the live yeast works on them. Then just wash as normal. Also a solution of yeast on a paper towel can be used to remove it from the desk.
 
Sounds fab haha I would love a duck egg blue or tie dyed labcoat :p
Dylon, not sure if they do Duck Egg, but certainly light blue, just put on a 30 degree wash with dye in drum, permanent & easy.
Coloured ones to buy are much more expensive.

Great tip, didn't know this.

Brilliant! We have had more than one incident with methylene blue. On an aside, regarding strange coloured labcoats ... just send them to my daughter to launder. I have a peculiar array of colours thanks to odd socks left in the wash when it goes onto boil ...
