Puerto Verde citric acid is a natural descaler that removes limescale from taps, appliances, and household surfaces without resorting to harsh chemicals. Available as a powder and a ready-to-use liquid, it is one of our star products: concentrated, biodegradable, and highly versatile, for both routine home maintenance and deeper descaling.
What is citric acid and what is it used for?
Citric acid is a natural acid of plant origin, highly effective at dissolving limescale and mineral deposits that build up with hard water. Unlike conventional descalers, it is biodegradable and leaves no toxic residues, while being just as effective for everyday household tasks.
It is used to descale washing machines, dishwashers, coffee makers, and kettles, remove limescale from taps, shower screens, and tiles, and as a base for homemade multi-purpose cleaners. You can find a complete guide to its uses, with step-by-step proportions and tips, on our citric acid uses page.

Citric acid powder vs liquid: which should you choose?
| Feature | Powder | Liquid |
|---|---|---|
| Preparation | Requires dissolving in water | ✓ Ready to use |
| Convenience for occasional use | Medium | ✓ High |
| Yield per quantity | ✓ Highly concentrated | Concentrated, already diluted |
| Ideal for | Preparing your own mixtures and large volumes | Quick applications, direct spraying |
| Shelf life | ✓ Very long in dry powder | Long, keep tightly closed |
Both formats are equally effective against limescale: the choice depends on how you use it, not its potency.
How to use citric acid step by step
- With the powder format: dissolve the recommended amount in hot water until completely dissolved, and apply the solution to the surface or appliance to be descaled.
- With the liquid format: apply it directly to the area with limescale, or add it to the washing machine drawer or appliance reservoir as appropriate, with no need to dilute.
- Leave to work: depending on the amount of limescale accumulated, leave the product to work for 15 to 30 minutes to properly dissolve mineral deposits.
- Rinse with water: remove residue with a cloth or sponge and rinse the surface thoroughly or run a rinse cycle on the appliance.
You will find exact doses and recipes for each appliance and surface in the complete guide to citric acid uses and on our natural products blog.
