We recently moved back to Utah and we are currently renting a home. Our shower is older and gets clogged up all the time. It drives me nuts! I got tired of buying expensive drain cleaner from the store, so I set out to find a home recipe to try out and I found this one here. I gave it a try and it worked pretty well. I had to do this twice to get it to really work but as I said our shower is older and could probably use a professional cleaning, so this should work great for just your average clog.
Pour a 1/2 cup of baking soda down the drain, then pour half a cup of vinegar down. Place a wet face cloth over it and let it sit for 5 minutes and then wash it down with hot water.
