As with any natural material, existing fluids and moisture can leach over time. A natural process of teak involves oil moving to the surface of the teak.
This natural process of teak oil leaching can cause staining; this can be especially evident if the furniture pieces are experiencing exposure to weather elements, particularly rain.
We do not recommend placing this natural timber piece directly onto carpets or rugs. Moisture will generally seep through the ends of the timber. If placing it onto carpets or rugs, markings may be avoided by using a protective liner such as thick plastic.
None of the above is viewed as a fault; we embrace these changes as the natural characteristics and beauty of timber furniture.
