The wood polishing work is my second polishing work. The non-toxic lemon based polish is safe for the child to use and builds on a child's use of a dropper. It is available from Montessori Services. The child uses the apron (at left) to protect their own clothing. They then apply the polish with an applicator, invert the timer, wait until the sand runs out, use the cotton balls and the flannel cloth to remove the excess polish and buff to a shine. The sponge allows clean up of any spills.
