I got a magnetic broom to help cleanup after practice. It seems that no matter how long we had cleanup that some screws, nuts. set screws and washers got missed. Using this I am able to get the lab MUCH CLEANER in a short amount of time.

We tried using magnets to pick up screws, but most of them are stainless steel so they do not attach to it.
