The range of laundry strips is growing rapidly, but the differences in quality are significant. One criterion is not enough — a good strip must perform well on multiple points.
1. Solubility — including in cold water
This is the most underestimated criterion. A laundry strip that does not dissolve completely leaves white marks on dark clothes and works less effectively. Good strips dissolve within a few seconds, even at 30°C.
Trying a new strip for the first time? Drop it into a glass of cold water and see how quickly it breaks down. If pieces are still floating after a minute, that is a bad sign for what happens in your machine.
Some suppliers only state that their strips "dissolve" — without specifying at what temperature. Cold water (15–20°C) is the fairest benchmark.
2. Ingredients — what isn't in it matters too
The ingredients list of a laundry strip tells you more than the packaging. Here are a few things to check specifically:
✓ Favorable
- Fragrance-free option available
- No microplastics
- Enzymes for stain removal
- Clear ingredients list
✗ Less favorable
- Only fragranced variant
- Unclear ingredients list
- No test method specified
- Chlorine or bleaching agents
For those washing clothes for babies or people with eczema, a fragrance-free option is not a luxury but a necessity. Pay attention to the difference between "fragrance-free" and "subtle fragrance" — the latter still contains fragrance ingredients.
3. Price per wash
The price on the packaging says little without knowing how many washes it contains. Always calculate the price per wash — that is the fairest basis for comparison.
With traditional liquid detergent, you also pay for the water it contains and the plastic bottle around it. Laundry strips don't have that extra weight, which often makes the price per wash lower. A realistic price for a high-quality laundry strip is around 15 to 25 cents per wash.
The Lavoa laundry strips cost from €0.16 per wash — and can be ordered in bundles if you do laundry more often.
4. Packaging and delivery
A laundry strip only has a real advantage over a bottle if the packaging is also plastic-free. Cardboard boxes are standard among most reputable providers — but check whether the strips themselves are also individually wrapped in plastic bags inside.
The compact size is practical too: a good laundry strip fits through the letterbox. That means no missed deliveries and no trip to a collection point.
- Cardboard packaging, with no plastic wrapper inside
- Compact enough to fit through the letterbox
- Clear dosing instructions on the packaging
- Best-before date stated
Frequently asked questions about buying laundry strips
Are laundry strips as effective as liquid detergent?
With high-quality strips, yes. The difference lies in their solubility and the concentration of active ingredients. A strip that dissolves well and contains enzymes performs comparably to an average liquid detergent — even at low temperatures. Cheap strips without enzymes do not reach that level.
What is a fair price per wash for laundry strips?
Expect to pay 15 to 25 cents per wash for a high-quality strip. Cheaper options are available, but they generally cut back on the active ingredients. A single box of Lavoa costs €0.23 per wash; with a larger pack, this drops to €0.16.
Are laundry strips suitable for sensitive skin?
That depends on the composition. Always choose a fragrance-free option if you have sensitive skin or are washing clothes for babies. Fragrances are by far the most common trigger of skin reactions.
Do laundry strips also work on a hot cycle?
Yes, laundry strips work at all common temperatures. Most are specifically optimized for cold washes (30–40°C), as this is the most commonly used setting. They also work perfectly at 60°C or 90°C — you don’t need a separate strip for a hygiene wash.
How do I know whether a laundry strip is truly plastic-free?
Don’t just check the outer packaging; also check what’s inside. Some providers use a cardboard box but still package the strips in a plastic bag inside. A completely plastic-free supply chain means: cardboard on the outside, no plastic inside.
