I used to postpone cleaning my brushes because I felt like the bristles were loosing their tightness and I didn't like that. But then I came across these Brushguards which you can use for cleaning, traveling or even for storing your brushes. It's basically a bunch of plastic holders that keep the bristles tight and clean. One pack contains 6 brushguards in 4 different sizes. They are available online here and cost €4,95 per variation pack. I know it's not the cheapest, but it's SO worth the investment. Wether your brushes are expensive or not, it's very important to take good care of them. It makes them last way longer. I hope this was a helpful tip! :)
