Hint and tips

Tools should be cleaned with warm water and Auro Plant Soap 411 can be added. It can be a good idea to leave brushes soaking in water and a few drops of plant soap in storage. This will keep the bristles there best before being used the next time. If necessary Auro Orange Oil 191 can also be used to clean tools.
