Both the rungs and the sides of the rocker can be cleaned with a damp cloth.
How to clean rocker skids?
It may happen that dirt, pebbles or other elements from the carpet, matt or other surface get stuck inside the rocker’s skids.
The skids can be sanded with 120 grit sandpaper, then 320 grit and polished with oil (e.g. linseed, coconut).
To do this, take a cotton cloth, dip it in oil and rub it over the edges. Wipe dry.
The edges will turn from light to dark, which is a natural process.
