It seems as if most drain cleaners involve the use of toxic chemicals. Even if you are careful about how you store an ordinary drain cleaner, making sure to keep it away from children and pets, they will still release potentially dangerous fumes when you finally use them. Considering that you may not always have access to adequate ventilation when you work on your drain, this can be a serious drawback. Luckily, there are plenty of simpler ways to clean a drain that involve no dangerous chemicals whatsoever. You can make your own drain cleaner out of household items. These items are non-toxic, so you don’t have to worry about storing or using them. First, pour 3/4 cup of baking soda down your drain. Next, add 1/ 2 cup of vinegar. The measurements do not need to be exact. Wait 30 minutes for the baking soda and vinegar to do their work. When they are completely done, pour hot water down your drain. This should wash away whatever is left of your drain clog. If your drain cleaner does not work, you should attempt to use a plunger to remove the clog from your drain. While a plunger is hardly a replacement for a harsher solution, it has the advantage of requiring no dangerous chemicals. If you are using your plunger on your sink or bathtub, fill it up partly with water. This puts pressure on the clog and will make it obvious if and when it breaks. Once you have done this, you can begin. Place your plunger over the drain, pressing down to seal off the business end against it, and push down firmly. Repeat this process. Occasionally check to see if the clog is broken by lifting the plunger and allowing water to drain out, if it is able to. Plungers, unfortunately, will leave pieces behind of whatever is clogging your drain, potentially allowing other sticky materials to build up in the same place again. If you have repeated problems with your drain and cannot solve them with a plunger, you will need to try another method. A drain snake is the most powerful way to unclog a drain, and on top of this, it requires no chemicals whatsoever. You can unclog your drain with a drain snake by placing the unclogging end in your drain and holding the handle carefully. Turn the drain snake’s crank to extend the drain snake down your pipe. Continue to extend the drain snake until the crank becomes the slightest bit hard to turn, and then stop immediately. If this happens, you have probably struck the clog. Turn the crank in reverse until the snake is fully separated from your drain, and then remove it completely. You should see pieces of the clog on the end. Clean them off, and then repeat the whole process. You will know that you are finished when water can go down your drain.
