Naiked Eco Cleaning Sprays & Refill Tabs Review: Are They Worth It?
Refillable cleaning products have gone from niche curiosity to genuinely practical option in the past few years. The concept: instead of buying a new plastic bottle of cleaning spray every few weeks, you buy one reusable bottle and drop in a concentrated tablet that dissolves in water. Full-strength cleaner, no new plastic.
Naiked is a German brand that makes a complete system of four cleaning tabs (kitchen, bathroom, glass, floor) plus reusable spray bottles from recycled PET. We have been using the full range across multiple rooms for several months. This review covers every product in the system: how each tab cleans, how the bottles hold up, what it costs compared to supermarket sprays, and whether it is actually worth switching.
What Is the Naiked Cleaning Tab System?
Each tab is a compressed, concentrated plant-based cleaning formula. Fill a spray bottle with 500ml of tap water. Drop in the tab. Wait two to three minutes. You now have a full bottle of cleaning spray. The tabs come in compostable wrappers, so the only non-compostable part of the system is the reusable bottle, which is made from recycled plastic.
Four variants, each formulated for a specific job: Kitchen (worktops, splashbacks, appliances), Bathroom (tiles, taps, shower screens), Glass (mirrors, glass doors, chrome), and Floor (all water-resistant hard floors). All four cost £1.89 and produce 500ml of cleaner.
You need a spray bottle. Naiked sells recycled PET bottles in three colours (£3.89 each), but any spray bottle you already own works. The Naiked bottles are unlabelled so you assign colours however you like.
Every Naiked Cleaning Tab Reviewed
Kitchen Cleaner Tab
The workhorse. Dissolves in about two minutes. Clear spray, mild lemon scent that does not linger. We used it daily for several weeks on laminate worktops, tiled splashbacks, stainless steel appliances, and painted cupboard doors.
On everyday grime it performs well. Cooking splashes, sauce marks, grease film: one spray and wipe. Heavier grease around the hob after frying needs a second spray and thirty seconds to soak, but it clears. No streaks on glossy surfaces. No residue after drying.
Where it is less effective: heavily burnt-on grease on oven exteriors. But that is true of most conventional multi-surface sprays too. For those jobs, pair it with a scrubbing brush or copper sponge.
Verdict: Strong daily performer. Handles 90% of kitchen cleaning without fuss. Our most-used tab by a wide margin.
Bathroom Cleaner Tab
Targets soap residues, water stains, and limescale. We tested it on ceramic tiles, chrome taps, a glass shower screen, and a porcelain basin. Soap scum and water marks came off cleanly. Spray, leave a minute, wipe.
Limescale: good on light-to-moderate buildup. Fresh spots around taps dissolved in one application. Heavier limescale that had been left several weeks needed two goes with a five-minute soak and a scrub with a loofah. Reasonable. Heavy limescale is a challenge for any cleaner.
No bleach in the formula, so it will not whiten grout or shift deep mould stains. For weekly maintenance it is entirely sufficient. For a deep clean after months of neglect, you may need to supplement it.
Verdict: Excellent on soap scum and light limescale. Not a heavy-duty descaler, but few conventional sprays are either.
Glass Cleaner Tab
Streak-free cleaning on mirrors, glass shower doors, windows, and chrome. We tested it on bathroom mirrors, a glass splashback, and kitchen windows. Fingerprints, dust film, grease marks, water spots: all removed without visible streaks when light hits the surface at an angle. That is the real test for glass cleaners, and this passed cleanly.
The most specialised of the four. If you are only buying two tabs to start, kitchen and bathroom cover more ground. But if you clean mirrors or glass shower screens regularly, this earns its place.
Verdict: Does exactly what it promises. Streak-free on glass and mirrors. Worth adding if glass cleaning is a regular job in your home.
Floor Cleaner Tab
The odd one out. You do not use this in a spray bottle. Dissolve the tab in 500ml of water, add the solution to a mop bucket or apply directly with a damp mop. Designed for tile, laminate, vinyl, and sealed wood.
We tested it on kitchen floor tiles and hallway laminate. It cleaned well. Footmarks gone, floor noticeably fresher. No sticky residue, which matters on laminate and vinyl where residue buildup dulls the surface over time. Mild scent, not perfumed.
One thing to know: 500ml is tight for floor cleaning. A typical kitchen floor needs more solution than that. We used two tabs per full floor clean, so the cost per mop is £3.78. Still cheaper than most eco floor cleaners (£4 to £7 per bottle), but worth planning for.
Verdict: Good cleaning performance. Budget for two tabs per floor clean on anything bigger than a galley kitchen. Still cost-effective.
The Naiked Recycling PET Spray Bottles
Well-made. The spray mechanism produces a fine, even mist with good coverage. Noticeably better than the cheapest trigger sprays you find on pound-shop bottles. The recycled PET is sturdy and does not feel like it will crack if you drop it. After several months of regular use, the bottles we tested showed no degradation, no leaking, and the spray mechanism still worked consistently.
The colour-coding is a practical touch. We assigned blue to bathroom, green to kitchen, pink to glass. The bottles are unlabelled, so you pick whatever system makes sense. If you already have reusable spray bottles at home, you do not need these. Any 500ml bottle works. But if you are starting from scratch, they are a solid buy.
Cost Breakdown: Naiked Tabs vs Conventional Cleaning Sprays
This is where the system makes its strongest argument. Here are the numbers for a household that cleans the kitchen and bathroom weekly, glass fortnightly, and floors weekly:
| Product | Naiked Annual | Conventional |
|---|---|---|
| Kitchen spray | £22.68/yr £5.78 setup + £1.89/month | £36–£48/yr |
| Bathroom spray | £22.68/yr £5.78 setup + £1.89/month | £36–£48/yr |
| Glass spray | £11.34/yr fortnightly use | £18–£24/yr |
| Floor cleaner | £45.36/yr 2 tabs per clean | £48–£84/yr |
| Annual total | £102.06 | £138–£204 |
Setup cost: £19.23 (three bottles plus four tabs). After that, monthly spend is about £8.51. The system pays for itself in two to three months. Annual saving: £36 to £102 depending on what you currently spend.
The savings come from two things. The tabs cost less per 500ml than pre-mixed sprays. And you stop paying for the water and plastic bottle that make up over 90% of a conventional spray's weight and cost. You are paying for the concentrated cleaning formula only.
How Much Plastic Does This System Actually Save?
A typical UK household goes through 12 to 16 bottles of cleaning spray per year. Each conventional 500ml bottle weighs 30 to 40g of plastic. That is 360 to 640g of single-use plastic heading to recycling (best case) or landfill every year.
With Naiked, you buy three or four bottles once. Same weight of plastic, but reused indefinitely instead of discarded. The tabs come in compostable wrappers weighing under 2g each. Over a year, your plastic saving is essentially the full 360 to 640g, replaced by near-zero packaging waste.
Transport footprint drops too. A Naiked tab weighs a few grams and can ship in a letter envelope. A conventional 500ml spray weighs over 500g. Per unit of cleaning product delivered, the tab system uses a fraction of the fuel and space.
Who Is the Naiked System Best For (and Who Should Skip It)?
It works well for households that use spray cleaners regularly across kitchen, bathroom, and glass surfaces. For families looking to cut single-use plastic without adding hassle. For anyone who has looked at the price of a branded cleaning spray (£3.50 for what is mostly water) and thought there must be a better option. There is.
It works less well for people who clean very infrequently. If you use one bottle of spray every three months, the savings are minimal and the system is solving a problem you do not really have. It is also not for heavy-duty industrial situations. Commercial kitchens, workshop degreasing, medical-grade disinfection: those need specialist products. And if you want your kitchen to smell like a tropical island after cleaning, the Naiked tabs have a mild, clean scent but they are not heavily perfumed.

Full-home setup in one purchase:
| Product | Covers | Price |
|---|---|---|
| Spray Bottle: Pink | Glass cleaner | £3.89 |
| Spray Bottle: Green | Kitchen cleaner | £3.89 |
| Spray Bottle: Blue | Bathroom cleaner | £3.89 |
| Kitchen Cleaner Tab | Worktops and surfaces | £1.89 |
| Bathroom Cleaner Tab | Tiles, taps, shower | £1.89 |
| Glass Cleaner Tab | Mirrors, glass, chrome | £1.89 |
| Floor Cleaner Tab | All hard floors | £1.89 |
| Complete system | £19.23 |
After the initial £19.23, monthly cost is about £8 to £9 in replacement tabs. The bottles last indefinitely. For a household currently spending £12 to £17 per month on conventional sprays, this saves money from month three onwards. And zero plastic bottles in the recycling bin.
Frequently Asked Questions
How long does a Naiked cleaning tab last?
Each tab makes 500ml of spray. For most households, one kitchen tab and one bathroom tab per month covers weekly cleaning. Glass tabs last longer since glass cleaning is usually fortnightly.
Can I use my own spray bottle with Naiked tabs?
Yes. Any spray bottle with 500ml capacity works. The Naiked bottles are convenient if you need new ones, but not required. Old spray bottles from finished products work fine. Rinse them out first.
Are Naiked cleaning tabs safe for children and pets?
The tabs are plant-based and free from chlorine, phosphates, and synthetic fragrances, making them generally safer around children and pets than conventional chemical cleaners. Store undissolved tabs out of reach. The dissolved spray should be used as directed.
Do the tabs dissolve completely?
Yes. All four variants dissolved fully within two to three minutes in room-temperature tap water in our testing. No residue, no sediment, no undissolved material. Warm water speeds it up slightly but is not necessary.
Are refillable cleaning sprays as effective as conventional ones?
For routine household cleaning, yes. The tabs produce a cleaner that performs comparably to mid-range conventional sprays. They are not industrial degreasers, but for the 90% of cleaning tasks that make up normal household use, they work well.
What is the shelf life of a Naiked cleaning tab?
Undissolved tabs last 12+ months stored cool and dry. Once dissolved, use the spray within a few weeks, same as any water-based cleaning solution. In practice, a 500ml bottle gets used up well within that time.
Our Verdict
The Naiked tab system is one of the most practical refillable cleaning products we have tested. It is not a compromise. You do not give up cleaning performance, convenience, or money to use it. On cost alone, it is cheaper per use than most conventional cleaning sprays from UK supermarkets.
The tabs dissolve quickly. The sprays clean properly. The recycled PET bottles are well-made and last. The system eliminates single-use plastic bottles entirely, cuts transport emissions, and generates near-zero packaging waste.
If you want to try one product first, start with the Kitchen Cleaner Tab. It covers the room you clean most often and shows you exactly how the system works. If it delivers (and based on months of use, we expect it will), adding bathroom, glass, and floor tabs is straightforward. The economics only improve as you scale up.
