All our products are coated with Osmo 3040 water-repellent wax oil. The oil penetrates the wood and soaks it from the inside, while the wax creates an invisible film that protects against dirt and moisture. Thanks to this, the lamps practically do not need special care: it is enough to regularly wipe the product with a damp cloth to remove dust.
Stubborn dirt can be removed with P320-P600 grit sandpaper. After that, it is recommended to apply a new layer of wax oil.
We recommend renewing the coating every 5-7 years by applying one new layer of wax oil.
