Pigment, on the other hand, is made up of a fine powder and isn't permanent. Dye, as the name suggests, is a permanent solution that has been chemically formulated to stain fabrics, making them resistant to water and to detergent (to a certain degree). The reason that bingo dauber ink does not stain (and is non-toxic) is because it's made of pigment as opposed to dye. Just make sure you throw in a colour catching sheet to be extra safe. This is great news for those who do have a little playing accident – whether your bingo dauber comes in green, blue, yellow or even fluorescent pink, it’s no match for a normal wash with the rest of your clothing. Rather than something stronger like a permanent marker, bingo daubers have been designed to be translucent to display the bingo numbers on your playing sheet. The good news is, bingo daubers are totally washable. Ink stains on clothing are never a good look, so before you take up the hobby, it’s good to check if bingo daubers are washable. We’ve all been there – we’ve perhaps got a little over-zealous over a game of bingo and dropped it in our lap, or worse still, had a dauber fall into the wrong hands of a minor!
