To prevent damage to the wood such as shrinkage or swelling of a birchwood jug, the following care instructions should be observed: - Clean the jug only with a soft, dry, or slightly damp cotton cloth.
- Avoid excessive moisture and never leave water standing in or on the jug.
- Always wipe the wood in the direction of the grain and dry it thoroughly immediately.
- Do not use harsh, acidic cleaners or microfiber cloths, as these can damage the surface.
- Maintain a stable room climate with a relative humidity between 45% and 55% to minimize wood movement.
- Regularly treat the wood with a suitable care oil, such as linseed oil varnish, to keep it supple and protect it from drying out.
