To each his own, and whatever works.....I don't put anything on my poop boards. They are painted so the wood is sealed. Every morning I use a 6" scraper and scrape everything into a bucket, I spray the boards down with vinegar and wipe them off. Done. Below the poop boards on the main floor I have shavings, which are spot cleaned if necessary and replaced likewise periodically as necessary, but with the poop boards they stay pretty clean.
