How to Keep Your Drains Clear (Without Calling a Plumber)

I want to be upfront about something: a lot of the drain calls we get could have been avoided. Not because homeowners are doing anything wrong, necessarily — most people just haven't been told what actually works and what makes things worse.

Here's what I tell my own customers when the job is done and we're standing in the kitchen.

**The monthly baking soda and hot water flush**

Once a month, pour about half a cup of baking soda down your kitchen drain, followed by half a cup of white vinegar. Let it fizz for five to ten minutes, then chase it with a full kettle of hot water. Do the same for bathroom sink drains.

This won't break up a real clog — don't expect it to. What it does is prevent the gradual buildup of soap residue, light grease, and organic matter that makes drains start running slow over months and years. It's maintenance, not a fix. Think of it like brushing your teeth: you're not fixing a cavity, you're preventing one.

**What not to put down your drains (and why)**

Grease is the biggest offender in kitchen drains. Bacon fat, cooking oil, butter — all of it looks liquid when it's hot. The moment it cools in your pipe, it solidifies and starts collecting everything else that goes down with it. Over time, that grease layer builds up into what plumbers call a "fatberg." Do not pour grease down the drain. Pour it into a container, let it cool, and throw it in the trash.

Coffee grounds are sneaky. They don't dissolve. They collect in the trap and the pipe, especially combined with grease, and create dense clogs that are surprisingly hard to clear. Same goes for pasta, rice, and other starchy foods — they absorb water and swell. If you have a garbage disposal, this is still true. A garbage disposal is not a food trash can.

"Flushable" wipes are not flushable. I know the package says they are. I have pulled them out of main sewer lines by the garbage-bag-full. Unlike toilet paper, which is designed to break apart in water almost immediately, wipes hold together. They catch on the inside of aging pipes, collect debris, and build clogs that require real equipment to clear. Toss them in the trash.

Hair in bathroom drains is more about management than avoidance. A simple hair catcher in your shower drain costs a couple of dollars and keeps the most common source of bathroom clogs out of your pipes entirely. Clean it every week. It takes ten seconds.

**Enzyme cleaners vs. chemical drain cleaners**

If you're looking for something to use monthly beyond the baking soda flush, enzyme-based drain cleaners are genuinely useful and completely safe for your pipes. They introduce bacteria that digest organic buildup — hair, soap scum, food residue — over time. Green Gobbler, Bio-Clean, and similar products work on this principle. Use them as directed and they do keep drains fresher and flowing better.

Chemical drain cleaners — the kind that involve lye or sulfuric acid — are a different story. They can clear a clog in the short term, but the chemicals that eat through organic matter also damage your pipe walls, especially in older homes with cast iron drains. They heat up in the pipe, which is bad for PVC and ABS plastic pipes. If they don't fully clear the clog and you call a plumber afterward, we now have to work around corrosive chemicals sitting in the pipe. More importantly, they mask the underlying problem rather than fixing it. I'd rather you call me than pour Drano in repeatedly for six months.

**When DIY genuinely won't cut it**

If your kitchen sink and your nearby bathroom sink are both slow at the same time, that usually means the problem is past both of their traps — in a shared line or the main stack. A drain snake you rent from a hardware store probably won't reach far enough, and if it does, you may not be able to apply enough force to break through what's there.

If you've got a slow drain that's been slow for months and nothing you've tried has made a lasting difference, something structural may be going on — a buildup deep in the line, a partial root intrusion, or a pipe belly that traps debris. That's worth a camera look.

And if you have any sewage odor coming up from drains, that's a main line issue and you should call a plumber. Don't wait on that one.

For everything else — the regular stuff, the slow bathroom sink, the kitchen drain that's getting sluggish — the tips above will serve you well. If you ever need backup, ARG Plumbing is a call away at (832) 419-3411. We're happy to help, but we're even happier when you don't need us.
