For a treadle that had belonged to someone in my family? I wouldn't sleep until it was done! ~laffin~
The others are right...set the timer for 5/10/15 minutes and clean like a madwoman for that time...then do something else for a bit, and go back and set that timer again. I bet you find that you work past the timer bell....and once you get started, you're not going to want to stop!
