The aptly-named ‘ear cheese’ smell is sometimes accompanied by a greyish-coloured gunk – and it’s completely normal.
It's basically a build-up of oil and the dead skin cells that you've shed.
As you know, your body is constantly renewing and replacing skin cells - and because your ears are hard to clean - this can lead to a build-up of the cells, which mix with your natural oils.
While ear cheese is normal, you can take some steps to minimise it.
Make sure you remove your earrings while you shower and thoroughly wash your ear piercings with soap and warm water.
