On the Subject of Housecleaning

Who left this banana peel T on the ground?!

On the module is a 5×5 section of a grid below. Locate this section and clean the spaces.

Trash will be invisible to the defuser’s eyes.

Press the button with the same letter as square, then press a square.

Once the section is clean, the module will solve.

If an incorrect item is used for a space, the module will detect it and issue a strike.
