How to Clean Bathroom and Kitchen Drains
Slow or smelly drains are one of the most common household complaints. Hair, soap scum, grease, and food debris build up in drain pipes over time, causing slow drainage and unpleasant odours. Regular maintenance keeps drains clear without needing chemical drain cleaners, which can corrode pipes over time.
Bathroom Drain — Hair and Soap Scum
The most common bathroom drain blockage is hair combined with soap scum. Use a drain snake or a plastic hair removal tool (inexpensive at hardware stores) — insert it into the drain and rotate or pull upward to extract the clog. This physically removes the blockage rather than just pushing it further down. After clearing the clog, pour boiling water slowly down the drain to dissolve soap residue.
Deodorizing with Baking Soda and Vinegar
Pour ½ cup of baking soda down the drain, followed by ½ cup of white vinegar. The fizzing reaction breaks up residue and neutralizes odours. Cover the drain for 10–15 minutes to keep the reaction inside the pipe, then flush with boiling water. This is safe for all pipe types and works for both bathroom and kitchen drains.
Kitchen Drain — Grease and Food Buildup
Never pour cooking grease down the drain — it solidifies in pipes. For existing grease buildup, pour boiling water with a few drops of dish soap down the drain weekly. For a deeper clean, use the baking soda and vinegar method above. If the drain is slow despite cleaning, the blockage may be deeper in the P-trap — remove and clean the P-trap under the sink by hand.
Preventing Drain Buildup
- Use a drain catcher/hair strainer in shower and tub drains
- Flush kitchen drains with hot water after washing dishes
- Do a baking soda and vinegar flush monthly
- Never put fibrous foods, grease, or coffee grounds down the kitchen drain
