      What Are The Different Ways To Unclog A Bathroom Sink Drain?

      Natural Remedies 

      A mild clog may only require a simple solution that you can do without going to the hardware store for any tools. 

      The first natural solution is boiling water. 

      The second natural solution involves a solution of baking soda and white vinegar (and optional lemon juice). 

      Plunger 

      A plunger uses pressure to break up clogs in more places than just the toilet. 

      The three main types of plungers are:

      • Cup plunger
      • Flange plunger
      • Accordion plunger 

      For a bathroom sink clog, use a cup plunger or flange plunger. 

      Drain Cleaner 

      A drain cleaner uses chemicals or enzymes to dissolve the clog. 

      A caustic drain cleaner that uses chemicals can potentially damage your plumbing system, and it can cause poisoning if ingested. 

      To remain safe, more and more homes are using enzymatic drain cleaners, but they don’t work as well on a stubborn clog. 

      Plumber’s Snake 

      The main problem with a clog is that you can’t reach it. A snake drain solves this problem. It has a flexible, long item that fits into your drain until it reaches the clog to break it up at the location. 

      You can find unpowered snakes as well as powered, cordless snakes.

      How To Unclog Bathroom Sink Drain (5 Steps)

      Step #1: Prep

      Whenever working on your plumbing, you need to prepare yourself for a mess. 

      Wear clothing that you don’t mind getting dirty. You also want to keep your phone and watch away from the water. 

      At this point, you should also do your research on the clog and the products you plan to use. 

      Step #2: Try a Plunger 

      If you have a small rubber plunger available, use it first. 

      Put the sink stopper somewhere safe and create a tight seal around the drain with a little bit of water in the sink. 

      Plunge for about 20 seconds and check the drain. 

      If you don’t notice much progress after 2 – 3 attempts, you may want to move on to another method. 

      Step #3: Use a Snake Drain 

      Slowly place the auger down the bathroom sink until you reach the clog. 

      When you have reached the clog, use the crank to turn the snake or turn on the power to a powered auger. 

      Step #4: Take Apart P Trap 

      You may need to remove the P trap to gain access to the clog.

      This requires moderate plumbing knowledge, and you may feel more comfortable requesting the services of a professional plumber for this task. 

      Turn the water off before you take apart the P trap, and use a bucket to catch any remaining water. 

      Use a screwdriver and pipe wrench to take apart the plumbing and find the clog to remove it. 

      This may not work if the clog occurs further down your plumbing system where you can’t reach it.

      Step #5: Apply Drain Cleaner Regularly 

      After you resolve the clog, pour a natural drain cleaner down your drain every month as a part of regular plumbing maintenance

      The enzymes eat and dissolve hair and other organic waste to prevent clogs before they happen

      In some cases, a drain cleaner can attack a stubborn clog, but it’s important to understand that they work best as maintenance, especially non-chemical drain cleaners. 

      You want to reduce how often you use a chemical drain opener so that it doesn’t damage your pipes, leading to early replacement. 

      What Do You Look For In The Best Products To Unclog Bathroom Sink?

      Environmentally Friendly 

      It’s important to take the planet into consideration in everything we do, even when dealing with a clogged drain

      Look for biodegradable products in recyclable containers from companies that follow eco-friendly manufacturing and business practices. 

      Safe For Pipes/Appliances

      You need the product you use to be safe for every pipe from the sink pipe to the drain pipe. 

      Metal pipes can be susceptible to corrosion, and PVC pipes don’t withstand harsh chemicals as well since they aren’t as strong as metal. 

      You should also check if you can use the product for your garbage disposal, washing machine, septic tank, grease trap, drain trap, and other sensitive areas of your plumbing. 

      Appropriate for Your Clog

      You can probably guess exactly what caused the clog, and you need to use a product specifically designed for your specific type of clog. 

      Some common items that can clog your bathroom drain include:

      • Toothpaste
      • Hair
      • Clay mask
      • Paint
      • Food waste
      • Soap scum
      • Grease
      • Paper products 
      • Foreign objects
