Before this project, I don’t think I’ve ever cleaned an entire floor on hands and knees before. Now I can’t even count how many times we’ve done it in the vain hope of trying to get what is potentially 20 years of dirt out of these tiles. Today we finally found the solution – baking soda.

Only 300 square feet to go!

Luckily, the new volunteers started working today, too. Each tile is one square foot. This is close to the end – maybe only 50 square feet left.
