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 as a ready-to-use liquid, it is one of our star products: concentrated, biodegradable and highly versatile, both for regular household maintenance and for 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 accumulate with hard water. Unlike conventional descalers, it works in a biodegradable way and without leaving toxic residues, being just as effective in 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 the complete guide to uses, with proportions and step-by-step tips, on our citric acid uses page.

Citric acid powder vs liquid: which one to choose?
| Feature | Powder | Liquid |
|---|---|---|
| Preparation | Requires dissolving in water | ✓ Ready to use |
| Convenience for one-off use | Medium | ✓ High |
| Performance per quantity | ✓ Highly concentrated | Concentrated, already diluted |
| Ideal for | Preparing your own mixtures and large volumes | Quick applications, direct spraying |
| Storage | ✓ Very long in dry powder | Long, keep well closed |
Both formats are equally effective against limescale: the choice depends on how you use it, not on 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 the appliance reservoir as appropriate, without the need to dilute.
- Leave to work: depending on the amount of accumulated limescale, leave the product to work for 15 to 30 minutes so that it properly dissolves the mineral deposits.
- Rinse with water: remove the residue with a cloth or sponge and rinse the surface well 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.
