What Are Soda Crystals, and How Do They Work?

Soda crystals can tackle many tough cleaning tasks at home, and honestly, they work better than most regular cleaners on greasy or stubborn dirt.
Soda crystals go by a few names—washing soda or soda ash—but their scientific name is sodium carbonate.
They look like small white granules or powder and dissolve fast in water.
They are particularly great at breaking down grease, fat, and dirt.
I find them excellent for unclogging sinks, cleaning laundry, or cutting through kitchen grime.
You can use soda crystals on a ton of surfaces. They’re not as harsh as bleach but can still lift stains and clean without those strong fumes.
Laundry and Fabrics
Soda crystals can really improve how clean your clothes get in the wash.
They help your regular detergent work better, tackle tough stains.
They can also work to soften water so that you can use less detergent.
All you need is about half a cup per full load—just toss it in with your usual detergent.
If you wash clothes with grease or oil, soda crystals break down those stains before the wash even starts.
I’ve noticed that using them makes clothes and towels come out fresher.
They also help keep your washing machine cleaner and free from bad smells, too.
How to Use:
- Add ½ cup of soda crystals to your wash.
- Use with your regular liquid or powder detergent.
Removing Stubborn Stains on Fabrics
Soda crystals work well as a stain remover for fabrics.
Dissolve about 2 tablespoons in hot water and let stained clothes soak for at least 30 minutes before washing.
This trick works on sweat, grass, and food stains.
Don’t use soda crystals on delicate fabrics like wool or silk—they’re just too strong for those.
Steps for stain removal:
- Dissolve soda crystals in hot water.
- Soak stained items.
- Wash as usual with laundry detergent.
Using soda crystals as a pre-soak can save you money since stains lift more easily, and you’ll use less stain remover over time.
In Your Kitchen
Soda crystals are a simple, affordable way to keep your kitchen cleaner.
They break down grease, clear drains, and remove stubborn stains from cookware.
Degreasing Ovens and Baking Trays
Sticky grease on your oven or trays is a pain, but soda crystals offer a great alternative to harsh oven cleaners.
Sprinkle a generous layer over the greasy areas and add a little hot water to make a thin paste.
Wait 15–30 minutes so it can break down grease and baked-on grime.
Scrub with a sponge or brush, and the grease should come off much easier than with just elbow grease alone.
For oven corners, dissolve soda crystals in hot water and use a spray bottle.
This method works for thin layers of grease or old spills.
Always wear gloves—soda crystals can irritate your skin if you’re not careful.
Oven Hood Filter

Oven hood filters can get really clogged up with sticky grease.
Remove and soak in hot water with a generous amount of soda crystals, and the grease will quickly melt away. This is so effective!
If you have a large filter, soak it in the bathtub instead.
Unclogging and Freshening Drains

Soda crystals come in handy for blocked kitchen drains.
Pour about half a cup down the drain, then slowly add boiling water.
This combo reacts with the fats and grease in pipes and breaks them apart.
It helps clear minor clogs and gets rid of nasty odors.
For tough blockages, you might need to try more than once or use a plunger after the soda crystals do their thing.
Use soda crystals once a week for routine drain cleaning—your kitchen drains will stay flowing and fresh without harsh chemicals.
Cleaning Pots, Pans, and Cookware
Burned-on food and stains on pots and pans are no match for soda crystals.
Fill the cookware with hot water, toss in a tablespoon or two of soda crystals, and let it soak for at least an hour.
After soaking, use a non-scratch scrubber to lift off food and stains.
Soda crystals soften the grime and work on stainless steel, Pyrex, and most metal cookware.
If you’re cleaning nonstick items, test a small spot first—just in case.
You don’t need extra soap; soda crystals and hot water usually do the trick.
Rinse cookware well after cleaning, since leftover crystals can leave a white film.
In Your Bathroom
Soda crystals make it easy to remove hard water buildup and keep surfaces looking clean.
You can tackle tough spots in the bathroom without harsh chemicals or strong fumes.
Tackling Limescale and Hard Water Deposits
Limescale builds up fast in bathrooms with hard water. It leaves white or chalky spots on taps, shower heads, and inside toilet bowls.
Soda crystals break down these deposits and make them easier to wipe away.
To clean limescale, sprinkle soda crystals on a damp sponge and rub the area.
For tough spots, mix soda crystals with hot water to make a paste and apply directly to the buildup.
Let it sit for 10–15 minutes, then scrub and rinse.
If you have stubborn limescale, use some distilled white vinegar instead. This works to dissolve the limescale.
Refreshing Tiles, Grout, and Floors
Bathroom tiles and grout pick up dirt and stains pretty quickly.
Soda crystals break up grime on both shiny tiles and porous grout lines.
Dissolve a cup of soda crystals in a bucket of warm water.
Mop the tiles or scrub grout with a brush dipped in the solution.
For grout lines, dip an old toothbrush into the mix and scrub gently.
This helps remove mold and soap scum without damaging tiles.
Soda crystals are less abrasive than most commercial powders, so they clean without scratching.
You don’t need bleach or heavy cleaners for floors.
After mopping, rinse with clean water to remove any leftover residue.
Your bathroom will look brighter, and surfaces will feel cleaner with less effort.
Other Surprising Things to Clean with Soda Crystals
Soda crystals aren’t just for general cleaning.
They work well on metals and keep garden tools and outdoor items in good shape, too.
Cleaning Silver and Other Metals

You can clean silver safely at home with soda crystals.
For small items like jewelry or cutlery, line a bowl with aluminum foil, shiny side up.
Place your silver on the foil.
Sprinkle 2-3 tablespoons of soda crystals over them and pour in enough boiling water to cover everything.
You’ll see bubbles as the tarnish lifts away.
After a few minutes, take the silver out, rinse well, and buff it dry with a soft cloth.
This trick also works for stainless steel, brass, or chrome.
But don’t use it on aluminum, gold, or painted surfaces—just to be safe.
Soda crystals act like borax, breaking down grime, but always rinse items thoroughly.
Reviving Outdoor Items and Garden Tools
Outdoor items and garden tools get dirty and rusty pretty fast. I usually soak them in a mix of soda crystals and warm water to get rid of mud, sap, and all that stubborn grime.
I dissolve about ½ cup of soda crystals in a bucket of warm water. Then I toss the metal tools in and let them soak for maybe 30 minutes.
After soaking, I scrub them with a brush. A quick rinse and a good dry, and they’re much better. This trick works on plant pots, plastic chairs, and even barbecue racks.
If the rust’s really stuck on, I make a paste with soda crystals and a splash of water. I grab an old toothbrush and scrub until the rust finally gives way.
Rinse well and dry everything right away—otherwise, more rust might show up. Honestly, this keeps my tools and outdoor stuff looking decent for much longer.
