Cleaning products are indispensable in the daily life of any home, business, or company. But although they sometimes accumulate on shelves or in warehouses for months, the truth is that they also expire .
At La Corberana , we are leaders in industrial cleaning products in Spain, so we can explain everything you need to know about the lifespan , expiration date , and storage of these products, so you can use them safely and effectively.
Do cleaning products have an expiration date?
Yes. Although many people are unaware of it, the vast majority of cleaning products have an expiration date or recommended shelf life . This information is usually indicated on the packaging, either with a specific date (day, month, and year) or with a symbol indicating the number of months the product will last once opened (for example, "12M" means 12 months).
The reason is simple: over time, active ingredients can lose effectiveness , oxidize, degrade, or even become irritating to skin or surfaces.
What happens if I use an expired cleaning product?
It depends on the type of product and the time elapsed since its expiration date. Generally, three things can happen:
-
Loss of effectiveness : This is the most common. For example, a disinfectant may no longer kill bacteria or viruses properly.
-
Physical changes : altered odor, phase separation, changes in color or texture.
-
Health risks : Some unstable ingredients may cause allergic reactions or irritation, especially in products containing ammonia, bleach, or strong acids.
Duration of cleaning products
1. Bleach (sodium hypochlorite)
Estimated shelf life: about 6 months once opened.
How do you know if it's expired? The characteristic odor diminishes and it loses its disinfectant power.
2. Detergents and dishwasher tablets
Estimated duration: between 6 months and 2 years, depending on the type.
What indicates they're no longer useful? Lumps, hardening, or loss of effectiveness.
3. Liquid or spray disinfectants
Estimated duration: around 12 months.
Signs of expiration: If it doesn't kill germs as well as before or has lost potency, it may be expired.
4. Multipurpose cleaners
Estimated duration: approximately 1 year.
What gives it away? Changes in color, an unpleasant odor, or separation of ingredients.
5. Glass cleaner
Estimated duration: up to 2 years.
What changes over time? It may lose its ability to leave glass streak-free and residue-free.
Helpful hint: If it has been stored for a long time, shake it before applying.
6. Floor cleaner
Estimated duration: between 1 and 2 years.
How do you notice expiration? It may thicken or show sediment.
7. Laundry detergent
Estimated duration: between 6 and 12 months from opening.
When does it stop working? If you notice the texture has changed or the ingredients are separating, it's probably past its prime.
8. Eco-friendly cleaners
Estimated duration: between 3 and 6 months.
How do you know they're no longer good? Bad odor, mold growth, or if they no longer foam.
9. Fabric softener
Estimated duration: 6 to 12 months.
Expiration symptoms: Weak fragrance, separation of components, or unusual texture.
Helpful tip: Close the container tightly to prevent evaporation.
And once opened?
Once opened, products are exposed to oxygen, moisture, and temperature changes. It's key to follow the manufacturer's recommendations here, but in general terms:
-
If the package has an open jar symbol with a number (for example, 12M), this indicates the number of months of use after opening.
-
If there is no symbol, a good practice is to write the opening date on the package with a marker.
-
Do not mix products or transfer them without labeling them: this could alter their composition or confuse their use.
What to do with expired cleaning products?
Ideally, you should n't use them , especially if they're disinfectants or contain strong chemicals. They also shouldn't be disposed of down the drain or in the regular trash. The best advice is:
-
Take them to a clean point or hazardous waste collection center.
-
Check with your local council to see if there are specific collections for cleaning products.
Tips to better preserve your cleaning products

-
