Since its inception in late-1900s Stockholm, every Iris Hantverk brush is handmade by visually impaired craftspeople in Sweden. This oil-treated birchwood and horsehair glass cleaning brush is no exception. A lovely way to treat handmade glass, and a simple beauty to behold in itself.
Dry thoroughly between uses, bristles facing down, and routinely oil the wood.
Use food grade oil or cold pressed boiled linseed oil and apply with a cloth. If linseed oil is used make sure to rinse the cloth properly in water to avoid fire hazard.
Let the oil soak well into the wood before using the brush again.
