The furniture has been soap-treated from the factory. If you like to give it an after-treatment you can do it in the following way:
First year you can give it a light soap-treatment. Use white soap-flakes or bio-soap.
After the first year you can give it a bit stronger soap-treatment.
Put on the soap-dissolution with a white cloth (woolen) slightly wrung.
NOTICE: not too much water on the furniture.
Remember always follow the grain of the wood and always both sides.
Wipe off with a clean cloth ( white)
The furniture can, when it is entirely dry, be polished with sandpaper no: 180/240 following the grain of the wood.
This treatment can be repeated, 1 to 2 times with a few weeks interval, after that only when needed.
