Stain removal is all about speed and technique. Here's the proven method for tackling pet hair effectively.
Use a vacuum with a pet hair attachment. Go over the area multiple times in different directions.
Put on dry rubber dishwashing gloves and run your hands over fabric. Static electricity from the rubber attracts hair.
For clothing or small areas, lint rollers pick up remaining hair quickly.
Run a dryer sheet over fabric to attract pet hair with static. Works on couches and clothes.
For clothes, run them through a dryer cycle on no heat with a dryer sheet to release pet hair before washing.
