Leave your toilet seat down. Men, this does not just apply to you. Ladies, leave the entire lid down.
There are a multitude of reasons why. The major one? Its gross to leave it open! But, also, in a feng shui sense its also a huge drain of waste and its constantly “running” even when not in use, as it is hooked up to your plumbing system.
Bonus points tip: ALWAYS majorly clean your toilet with organic cleaner, so you are not releasing pollution down the drains but maintain a sparkling bathroom space!
