SAFETY TIP 1: Never pour caustic drain cleaners into drains that are totally clogged. These cleaners can get trapped in your pipes, leading to more severe damage.
SAFETY TIP 2: If you have poured caustic drain cleaner into a drain, do not use a plunger on the drain. This could cause these dangerous chemicals to splash up while you are plunging.
If you have not used any caustic drain cleaners in your clogged drains, you can try unclogging them by using the tried and true plunger. In most cases, this inexpensive drain clearer will help to break up any clogs so that they can flow away. It may take several plunges to successfully unclog a drain.
Make sure there is enough water over your toilet or drain to cover the top of the plunger. (If you are unclogging a double sink, make sure to also plug the second sink’s drain).
Place the plunger in the water, while letting all of the air out of the cup. This tool only works when there is no air left in the cup.
Push the cup firmly against the drain so that it forms a seal.
Push up and down rapidly on the plunger. If there is little resistance, or you can hear water splashing around on a double sink, double check to make sure that the other drain has been plugged.
Whenever you are plunging a sink, flush the drain with hot water after the clog has been loosened.
If you can’t fix the problem with the plunger, pour a handful of baking soda mixed with 3/2 a cup of vinegar down the drain. Then pour 6 cups of boiling water in and let it sit overnight. In the morning, flush the drain with more water.
You can also buy enzyme drain cleaners at the store that may help with your clog.
