5. Next, I emptied the sink and put the makeup brushes inside the pillowcase. The pillowcase I used had a zip so I fastened it before then tying a knot in the top of the pillowcase.
6. I then put the pillowcase in the washing machine. When choosing a cycle for your brushes, choose one without a spin cycle that’s tailored to delicates.
I used my washing machine’s silk/delicate cycle which has a temperature of 30C.
7. The brushes were washed within around 30 minutes. When I removed them from the machine, there was no sign of any makeup residue on the pillowcase, in the machine or left on the brushes.
8. I removed the brushes from the pillowcase and left them to dry on two old tea towels.
