Eucalyptus is a material with life and it is constantly changing according to the climate.
Intense sun or dry weather can cause the wood to contract; in the case of heavy rain the wood will expand. These changes in climate can cause small cracks to appear, these are perfectly normal.
It may therefore be necessary to tighten all the screws annually.
The furniture has already been coated in a protective stain that will assure the beauty of the furniture for the life of the furniture. Over a number of years the furniture will naturally age and gradually turn a silvery grey colour. If you wish to maintain the original appearance of the furniture we recommend applying periodically Flaxseed oil.
In any case we recommend cleaning the furniture with water and a neutral soap
