I clean my rotary cutters once a month by taking them apart, cleaning out the fabric dust, putting a drop of sewing machine oil on the black base under the blade and reassembling. It's important to clean your cutters on a regular basis to prevent the buildup of fabric dust. Fabric dust causes your blades to drag and rotate unevenly while cutting. This causes your blade to dull in certain areas and not in others. We all know that can contribute to "skipping" while cutting and wearing out blades faster.
