Puerto Verde's sodium carbonate powder is a natural, biodegradable, multipurpose mineral, ideal as a powerful degreaser, water softener, and deep household cleaner. It is more alkaline than baking soda, making it the perfect ally for dissolving accumulated grease, removing limescale from hard water, and leaving fabrics, surfaces, and kitchen utensils truly clean without resorting to harsh chemicals.

What is sodium carbonate and what is it used for?

Sodium carbonate (also known as soda ash or soda) is a mineral salt with an alkaline pH, much higher than that of baking soda. That greater alkalinity is precisely what gives it its great degreasing power: it breaks down grease and ingrained dirt more effectively than milder products, without the need for solvents or synthetic chemicals.

For generations, it has been used in household cleaning to soften water before washing (which makes soaps and detergents last longer), degrease ovens and grills, clean tile grout, remove limescale from faucets and bathroom fixtures, and as a natural booster in the laundry. You can find the complete guide to its uses, with proportions and step-by-step tips, on our sodium carbonate uses page.

When should you use sodium carbonate at home?

To degrease the oven, grill, or stovetop with accumulated and burnt grease
To soften the washing water so that clothes come out cleaner with less detergent
To remove limescale from faucets, shower screens, tiles, and bathroom fixtures
To clean grout and floors with ingrained dirt
To unclog and degrease pipes when combined with cleaning vinegar
To remove grease stains from fabrics before regular washing
To clean silver utensils and restore their shine

Sodium carbonate vs. sodium bicarbonate: how do they differ?

Feature	Sodium carbonate	Sodium bicarbonate
pH / alkalinity	More alkaline	Milder
Degreasing power	✓ Very high	Moderate
Softens water	✓ Yes	✗ No
Use as a deodorizer	Limited	✓ Very effective
Mild abrasive for scrubbing	Moderate	✓ Ideal
Food use	✗ Not recommended	✓ Suitable
Best for	Ingrained grease, laundry, limescale	Odors, delicate surfaces, kitchen use

How to use sodium carbonate step by step

Degrease the oven: mix sodium carbonate with a little water to form a paste, apply it to the ingrained grease, leave it for 20-30 minutes, and remove it with a damp sponge.
Soften the laundry water: add one tablespoon of sodium carbonate along with your regular detergent in the washing machine drawer to boost its action, especially in hard water areas.
Remove limescale: dissolve sodium carbonate in hot water and apply it to faucets, shower screens, or tiles with limescale. Leave it for a few minutes and scrub with a soft brush.
Unclog pipes: pour sodium carbonate down the drain followed by cleaning vinegar. Let the reaction work for a few minutes and rinse with hot water.
General cleaning: dilute one tablespoon in one liter of hot water to create a multipurpose degreasing cleaner for floors and durable surfaces.

You will find more recipes and exact proportions for each use in the complete guide to sodium carbonate uses and on our natural products blog.

⚠ Before using it: As it is more alkaline, avoid using it undiluted on aluminum, anodized surfaces, or delicate metals, as it can damage them; always test it on an inconspicuous area. It is not suitable for food use or ingestion. Wear gloves if you have sensitive skin and keep it out of reach of children and pets.

Frequently asked questions about sodium carbonate

How does sodium carbonate differ from sodium bicarbonate?

Sodium carbonate is more alkaline and has greater degreasing and water-softening power, while sodium bicarbonate is milder, suitable for food use, and better as a deodorizer or delicate abrasive. They complement each other: sodium carbonate for ingrained grease and limescale, and sodium bicarbonate for everyday kitchen use and neutralizing odors.

Can sodium carbonate be used in the washing machine?

Yes, this is one of its most common uses: added along with the detergent, it softens the water and boosts its effect, especially in hard water areas. It does not replace detergent, but it reduces the amount needed and helps keep the washing machine free of limescale.

Is it safe for all surfaces?

It is safe for most durable household surfaces (ceramic, stainless steel, tiles, textiles), but as it is alkaline, it is not recommended for aluminum or anodized metals without being well diluted, as it can dull them. Always test it on an inconspicuous area before applying it to a new surface.

Can sodium carbonate be ingested or used in food?

No, sodium carbonate is not suitable for food use or ingestion, unlike sodium bicarbonate. Its use is intended exclusively for household cleaning. Always check the product labeling.

How does sodium carbonate remove limescale?

By softening the water and dissolving in it, sodium carbonate helps lift limescale deposits from faucets, shower screens, and bathroom fixtures when applied dissolved in hot water and left to work for a few minutes before scrubbing. For very ingrained limescale, you can combine it with our citric acid.
