Class I find the built-in brush. Simply moisten the stain and get started. Meanwhile, I have through almost the entire range of stain removers and can say this one is truly the best. I'll just have to buy this.
My little tip still on the edge with carrot stains on white / colored washing. Just hanging to dry in the sun. With colorful but not necessarily the blazing summer midday sun. After all residues are gone. In winter, however, does not work with me!
