All of our coffee parts have ergonomics in mind and are extremely robust to cope with the rigours of coffee environments. We stand behind our products, thus each piece comes with a lifetime guarantee for workmanship and refinishing.
For both the oil and beeswax and shellac finishes keep the wooden part of the portafilter clear when washing in water or cleaner fluid. Thus, do not plunge the wooden handle into any liquid as the surface will be affected and dull over time.
In the event that this occurs we recommend applying a coat of linseed oil, teak oil or wooden furniture polish, buffing to shine.
