Can I wash my blocks?

Yes! We recommend cleaning your blocks with a little vinegar and warm water on a soft cloth. You can always rub a little jojoba oil on your blocks if they start to lose their luster.  

Do you stain or paint the blocks?

We never use any paint or stain to color our blocks. All blocks are 100% naturally colored by nature. We use many different species of wood to provide a beautiful, natural mix of colors.

How natural and safe is the finish on the blocks?

We make our own finish from a mix of 100% organic beeswax and jojoba oil. This is a 100% non-toxic, natural and safe wood finish.
