A slow or stopped sink is stressful, but you can often unclog a kitchen sink with baking soda and vinegar before calling a pro. This safe, budget-friendly method can clear many grease and soap scum blockages without harsh chemicals. Below are seven easy tips any homeowner can follow, plus when to stop and call Del-Air for fast, same-day drain cleaning in North Orlando.
Before You Start: Safety, Tools, and When DIY Is Smart
A kitchen sink clog usually comes from grease, food particles, or soap scum. Baking soda and vinegar help because they create a fizzy reaction that can loosen buildup. Have these on hand:
- 1 cup baking soda
- 1 cup white vinegar
- Kettle or pot for hot water
- Sink stopper or towel
- Rubber gloves and a flashlight
DIY is smart for slow drains or recent clogs. Stop and call a pro if you notice sewage smells, repeated backups, standing water that will not budge after attempts, or if you have a septic system that backs up. Del-Air offers same-day plumbing across North Orlando and is fully licensed, bonded, and insured.
Tip 1: Clear and Prep the Drain Opening
Remove any standing water with a cup or small container so the reaction can reach the blockage. Pull the strainer basket and clean visible debris. If you have a garbage disposal, switch off power at the wall and the breaker, then check for obvious obstructions with a flashlight. Never put your hand into the disposal. A clear opening makes the baking soda and vinegar more effective.
Tip 2: Measure Right for the Reaction
Pour about 1 cup of baking soda directly into the drain. Follow with 1 cup of white vinegar. Immediately cover the drain with a stopper or towel to keep the reaction focused downward. The fizz you hear is carbon dioxide being released while the mixture breaks down light grease and soap residue. Let it sit for 10 to 15 minutes for best results.
Tip 3: Use Hot, Not Boiling, Water on PVC
After the wait, flush the drain with hot water for 1 to 2 minutes. If you have PVC pipes, avoid boiling water because extreme heat can soften pipe joints. Aim for hot tap water or water heated just below a rolling boil. For metal pipes, a controlled pour of very hot water can help melt grease layers. Repeat the baking soda and vinegar step one more time if flow only improves slightly.
Tip 4: Add Salt for Stubborn Grease
If the clog resists, mix 1/2 cup baking soda with 1/2 cup table salt. Pour it into the drain, then add 1 cup of hot vinegar. The salt adds abrasion that scrubs sticky buildup. Cap the drain and wait 15 minutes, then flush with hot water. This method is especially helpful after holiday cooking when fats and oils harden in the line.
Tip 5: Try a Plunger the Right Way
Use a cup-style plunger, not a toilet plunger. Seal the overflow hole with a wet towel for better suction. Fill the sink with a few inches of warm water, then plunge with short, firm strokes for 20 to 30 seconds. If you have a double-bowl sink, seal the opposite side with a stopper. Follow with another hot water flush. Do not overdo it if the sink refuses to drain at all, which can push the clog deeper.
Tip 6: Clean the P-Trap Safely
If water is still slow, place a bucket under the P-trap and loosen the slip nuts by hand or with adjustable pliers. Remove the trap and clean out sludge, then reassemble and hand-tighten. Rinse with hot water. This takes 10 minutes and solves many clogs that cleaners cannot reach. If you are not comfortable with this step or see corrosion, call Del-Air for a fast professional clear.
Tip 7: Prevent the Next Clog
Prevention beats repair. Simple habits keep the line clear:
- Wipe greasy pans with a paper towel before washing.
- Install a fine-mesh strainer and empty it daily.
- Run the disposal with cold water for 20 seconds after grinding.
- Monthly, flush with hot water, then use 1/2 cup baking soda and 1 cup vinegar.
- Schedule a plumbing inspection annually to catch slow drains early.
Central Florida’s hard water leaves mineral scale that traps grease, so prevention matters. Our local kitchens also see more sand and grit after beach days, which can settle in traps. A quick wipe and strain can save a service call.
When Baking Soda and Vinegar Are Not Enough
Some clogs need pro tools. Signs you should call us now:
- Water backs up into other fixtures, like the dishwasher or second sink bowl
- Recurring clogs after multiple DIY attempts
- Foul odors or gurgling from other drains
- Rusted or fragile piping that could crack under stress
Del-Air’s plumbers use a diagnostic-first approach to pinpoint the cause of your blockage and eliminate it. When needed, we can escalate from safe cabling to hydro-jetting for heavy grease and sludge. We also service water lines, sump pumps, and provide backflow testing and prevention.
Garbage Disposal Do’s and Don’ts
Disposals move food, not fats. Follow these quick rules:
- Do run cold water before, during, and after use.
- Do cut large scraps smaller and feed slowly.
- Do grind citrus peels for a fresh scent.
- Do not pour grease, oil, or fat down the drain.
- Do not grind fibrous items like corn husks or celery.
- Do not use chemical drain openers. They can damage seals and are unsafe for disposals.
If your disposal hums but will not spin, cut power, press the reset button on the bottom, and use an Allen key in the center hub to free the impeller. Restore power and test with water.
Double-Bowl Sink Strategy
Double sinks can trap air. Seal one side completely with a stopper while you treat the other. When plunging, alternate sides and keep the non-working side sealed. This preserves suction and moves the blockage instead of trading water between bowls. After clearing, run hot water through both sides for two minutes.
Facts That Keep You Safe and Effective

How long should I wait after pouring baking soda and vinegar?
Give it 10 to 15 minutes. Then flush with hot water for 1 to 2 minutes. For stubborn clogs, repeat once.
