Pigment, on the other hand, is very different. Because they can resist water, and, to a certain degree, detergent, they are ideal for permanent use but can be a nightmare if they stain fabric. Permanent markers may also contain oils which make them even harder to get out of fabric. This is due to its water-resistant chemical compounds, which is why dye ink is the ink of choice for permanent markers. Permanent dyesĪ dye, as the name suggests, has been designed to permanently change the colour of a fabric. Inks are divided into two basic groups: dyes and pigments. The science behind this all comes down to the ink contained within the pens. The difference between permanent and non-permanent inks Thankfully, most reputable bingo dauber brands are made using non-permanent ink, so you should be able to wash out any small spills with a standard machine wash and your normal detergent. The last thing we’d want is our favourite carpet or shirt turning into a very noticeable shade of pink. Stains are a nightmare for the house-proud bingo player in all of us, so before we take up the hobby, it’s wise to check if bingo daubers are permanent. Whether you’re playing bingo a little too enthusiastically or your bingo dauber has just got into the wrong hands, an ink stain is never a good look! Using any kind of ink-based implement as part of a hobby is bound to bring about an accident every once in a while.
