If you have tile in your bathroom or any other place in the house that has moister on a regular basis you must reseal your tiles and grout minimum every 6 mos to keep the grout from getting moldy and breaking down
If you have a door at home that's a little saggy and you want to rehang it but don't want to mess with the hinges stuff the stripped out holes in the frame with toothpicks
If you have a slow power steering leak use brake fluid instead of power steering fluid it will make any sealswell and works just like the reg steering fluid and won't hurt your power steering pump.
