So, I gave them a decent clean. It's so easy. All I needed was a shallow side plate, olive oil, anti-bacterial liquid hand soap, and kitchen paper. And I did it in the kitchen, near the sink for easy tap water access.
Firstly, I grabbed all my makeup brushes and had a good nosey. They were all a bit grim - especially my foundation brush? Yucky!
Grabbing the plate, I added 3 parts soap to 1 part oil. Then I layed down a paper towel next to the plate.
One brush at a time, I dabbed the brush into the middle of the soap and oil mix, then created a lather in the palm of my hand by circling the brush gently.
Once lathered up, I laid the brush on the paper towel, and continued with the rest of my bushes.
At the end, my side plate looked like this: gross!
Now, with fresh paper towel, and using lukewarm water from the tap, I rinsed the brushes. I made sure the brush faced down so no water seeped inwards towards the handle (this can loosen the glue). Using the circling motion again on the palm of my hand to rinse, I triple checked that the water ran clear before the next step. Finally, I gently squeezed the excess water out and re-shaped the brush, before setting it down to dry naturally on the fresh paper towel.
Ideally, brushes should be upside down to dry, and you can buy special equipment to do this. But I'm a busy mum of two, so the brushes will have to cope with drying on the side!
I left them to dry naturally for a good 24 hours, turning every few hours when it was possible. Done!
