Pamella and Julian finished cleaning the interior of the chamber, chamber lid, and the table. We found some black residue on the side of the table but not
sure what the issue is. A picture of the specific area of the table that is giving off the black residue is attached below. The next step from here would
be to flip the chamber on its side and finish the cleaning the exterior. |

keeping the same pattern in the shapes of the triangles. I have attached photos below. I was able to move left and right as well as up and down and it
worked in four points that I marked on the table.
