Homemade drain cleaner- my bathtub would not drain for...4 months now? Seriously, it would take at least an hour. And this (plus a bit of plunging) WORKED. All natural, no chemicals, hallelujah!
Homemade Drain Cleaner and Declogger from Food.com: For those of you who hate poison-type drain cleaners, use white vinegar and baking soda. This will clean and unclog a drain. Also drops of white vinegar in your pet's water will keep away fleas and ticks!
