Add a 1/2 cup of lemon juice and mix thoroughly to give your paste some extra declogging-power thanks to the juice’s acidity. If the clog is located deep within the pipe, or if you’re leaving the lemon juice out, add more vinegar for a thinner mixture so it travels more easily.
If you are unable to remove the stopper, add more vinegar to the mixture before pouring so it’s thinner.
Use boiling water instead of running hot water from the tap, since it may take a while for the hot water to kick in. Be careful about using boiling water on PVC pipes. The hot water can damage or loosen the pipe seals. [4] X Research source
