Put 1/2 cup baking soda into the entrance of the drain, add 1 cup white vinegar, it will fizz.
When the fizzing stops rinse well with hot water for 1 minute.

Pour the baking soda into the drain then add the vinegar. It will all fuzz up, i just add the plug and leave it for 30 minutes. Next add some hot water to flush it all down.
Hi Tessa, Start by pouring a pot of boiling water down the drain. Then pour a cup of baking soda and an equal solution of vinegar and water (1 cup water, 1 cup vinegar). Cover with the drain plug and wait 5–10 minutes. Flush the drain with boiling water.
If this hack fails- I recommend the fishing type barbed tools ( mine is from dollar tree) to remove obstruction.
Particularly shower and bathroom drains that are impacted by hair or shaving debris. Hope you solve your drain troubles.
I run hot water in the sink for a while, until it's steaming. Then I add baking soda to the sink and in the drain. I let sit for about 10 minutes and then pour vinegar around the sink and down the drain. It will bubble and fizz and after I let that sit for about 5-10 minutes, I scrub everything with warm water and Dawn soap.
Hi Tessa - Use 1 TBSP of baking soda, followed with 1/2 cup or more of vinegar. After it's finished fizzling, flush with boiling water. You will typically have to do it several times. I hope this helps! Hugs, Holly
