Yesterday dice, today rulers, tomorrow...?

Am I taking this a little too far? Yesterday I brought home a load of dice that had been covered in layers of stickers for various maths games (not by me) and spent a good hour de-sticking and cleaning them. Today I dumped a load of rulers in the sink and scrubbed with jif (still refuse to call it cif) tol they looked good as new. I wonder what I'll find to bring home tomorrow.
