How To Use Plastic-Free Cleaner Tablets (Step-By-Step)

When I first started sharing my sustainable cleaning guide, one of the most common questions I got was: “But how do you actually use those little cleaner tablets?”

It’s a fair question. Plastic-free cleaner tablets are tiny, a bit mysterious at first glance, and a total shift from the rows of plastic spray bottles we’ve all grown up with. After using them consistently in my own home for over 6 years, I can confidently say: yes, a tiny tablet really can replace your plastic-heavy routine. And honestly, it does a better job in more ways than one.

I made the switch for a few reasons. The first was simple: I was tired of the plastic waste. Every time I tossed an empty spray bottle in the bin (even the recyclable ones), it felt like a small loss.  But it wasn’t just the bottles. I also didn’t want to keep filling my home with harsh chemicals. I started questioning what I was spraying on my counters, around food, and near my pets. I wanted something safer, cleaner, and more aligned with the way I was trying to live.

Once I found plastic-free, dissolvable, eco-friendly cleaning tablets, I was hooked. They’re compact, cost-effective, and surprisingly powerful. And the best part? They eliminate the need for new bottles every time you run out.

In the following video, I’ll walk you through exactly how I use them in my kitchen and around the house.

What You’ll Need to Make Cleaner With Cleaning Tablets

• 1 refillable spray bottle (I use a glass one I’ve had for almost two years)
• 1 cleaning tablet
• 500 ml of lukewarm water
• A clean cloth or a plastic-free sponge

Step-by-Step Instructions

What Are Plastic-Free Cleaning Tablets?

Plastic-free cleaning tablets are exactly what they sound like — concentrated cleaning solutions in tablet form that you dissolve in water. These zero-waste kitchen swaps are designed to replace traditional spray cleaners that come in bulky, single-use plastic bottles. So, instead of buying a new bottle every time you run out, you just refill the one you already have, drop in a tablet, and you’re good to go.

What makes them so darn amazing isn’t just the format, but the philosophy behind them: less waste, fewer toxins, and a cleaner home without compromising your values. The average household throws away over 30 single-use plastic cleaning bottles per year, and most of them never get properly recycled. To put this into perspective, 80% of marine litter is plastic. The result is that over 1 million marine animals die each year due to plastic pollution alone. Shockingly, since 1950, more than 8 billion tonnes of plastic have been manufactured, but only 9 % has ever been recycled; almost half ends up in landfills. Not to mention that 100 % of baby sea turtles have ingested plastic, and 26 % of marine fish contain microplastics in their bodies—double the rate from a decade ago.

As we speak, there are 51 trillion microplastic particles floating on the ocean’s surface—and that’s just the tip of the iceberg. These eco-friendly tablets offer a simple way to cut down on that waste without giving up cleanliness or convenience.

They’re also biodegradable and water-soluble, meaning they break down safely in the environment and leave behind no harmful residue.  

What’s Inside These Eco-Friendly Cleaning Tablets?

One of the biggest reasons I made the switch was because I no longer wanted to spray harsh chemicals around my kitchen, especially on the counters where I cook. Plastic-free tablets are usually made from plant-based, non-toxic ingredients, and they skip the ammonia, bleach, and artificial dyes you’ll often find in traditional cleaners.

Most formulas include natural ingredients like citric acid (great for breaking down grease and grime), baking soda for a little scrubbing power, and gentle surfactants derived from coconuts or corn. Many tablets are lightly scented with essential oils like lemon, eucalyptus, or lavender — nothing overpowering or synthetic.

The result? A cleaning product that’s effective, safer for your family, and a whole lot easier on the air you breathe.

Different Types of Cleaning Tablets for Different Spaces

What’s great is that these tablets aren’t just “one size fits all.” There are different types available depending on the area you’re cleaning. I personally use a kitchen cleaner tablet for countertops and stovetops, but you can also find:

• All-purpose tabs for everyday messes
• Bathroom cleaner tabs for sinks, tubs, and tiles
• Glass cleaner tablets for streak-free windows and mirrors

Each tablet is clearly labeled, and once you mix it, you’ve got a cleaner just as powerful (if not more) than the usual stuff from the store — minus the chemical cocktail.

Pros and Cons of Switching to Cleaning Tablets

✅ The Pros 

Once I got into a rhythm, the pros became super clear:

• Less plastic waste — I literally haven’t thrown out a single spray bottle in over a year.
• Lower cost over time — the refill tablets are way cheaper than buying new products every month.
• No chemical headaches — I no longer get that harsh, artificial smell after cleaning.
• Takes up less space — no more under-sink chaos with half-used bottles.

Plus, there’s something weirdly satisfying about making your own cleaner in under five minutes. It makes you feel a little more connected to your routines.

And the Cons  

That said, it’s not 100% perfect:

• You do have to wait for the tablet to dissolve (especially in cold water — pro tip: use lukewarm).
• Not all tablets are created equal — some are better for grease than others.
• If you’re used to foam or strong scents, the experience might feel “too gentle” at first.

But honestly, once you adjust, you realize that clean doesn’t have to smell like bleach to be effective.

Best Eco-Friendly Cleaning Tablets in 2025

While there are so many amazing eco-friendly cleaning tablet brands on the market, I always find myself coming back to two favorites — they’ve earned a permanent spot in my routine.

1. Blueland
   Blueland’s tablets are plastic-free, plant-based, and come in compostable paper packaging. Their EWG-verified formulas are free from harsh chemicals but still incredibly effective. I use them constantly, especially in the kitchen and bathroom. They leave everything smelling fresh without that artificial, overpowering scent. I also swear by their non-toxic dish soap and dishwasher tabs — it’s a full system that just works.
2. AspenClean
   AspenClean is another brand I truly trust. Their products are EWG-approved, certified by Health Canada, and made with natural, skin-friendly ingredients. If you have kids, pets, or sensitive skin, these are a great option. Their cleaning tablets are gentle but effective, and I love that they prioritize sustainable packaging without cutting corners.

And while they’re harder to find, I have to shout out OecoLife tablets — they’re the exact ones I used in the video tutorial above. They’re zero-waste, work beautifully on greasy kitchen messes, and come with a subtle citrus scent I adore. Unfortunately, they’re only available in select places across Europe, but if you happen to find them, they’re absolutely worth trying.

My Tips for Using and Choosing Cleaning Tablets 

Use Lukewarm Water — Not Cold, Not Hot

I’ve tested this the hard way: cold water takes forever to dissolve the tablet, and hot water can sometimes affect the ingredients (especially with glass or essential oil-infused formulas). Lukewarm water — around 40°C (104°F) — dissolves the tablet quickly without damaging the active compounds.

Label Your Bottles Clearly

If you’re using different tablets for the kitchen, bathroom, and glass, label each bottle. It sounds simple, but once they’re all filled with clear liquid, it’s easy to forget which is which — especially if you store them under the sink. I use a little masking tape and a Sharpie or reusable vinyl labels.

Don’t Shake Too Hard

After the tablet dissolves, a gentle swirl is enough to mix it. Shaking too aggressively can create too many bubbles or foam, which makes spraying uneven. A slow, circular swirl is perfect for blending without mess.

Test on Delicate Surfaces First

Even though they’re non-toxic and plant-based, some tablets can be a bit too strong for natural stone (like marble) or unfinished wood. Always do a quick patch test the first time you use a new tablet on a sensitive surface — just in case.

Buy Tablets in Bulk (and Store in a Jar)

If you’ve committed to the switch, buy your tablets in a bulk refill pack. It’s cheaper per tab, and there’s less shipping and packaging waste. I keep mine in a glass jar with a lid, so they stay dry and easy to grab.

Use a Soft Microfiber Cloth for Best Results

You’ll get better cleaning power with a microfiber cloth instead of a rough sponge or paper towel. It’s especially helpful for streak-free glass and shiny countertops. I keep one in the kitchen and one in the bathroom just for this purpose.

Let the Bottle Fully Dry Between Refills

Before reusing your spray bottle for a new tab or scent, let it air dry completely. Mixing leftover solution or moisture with a new tablet can dilute the formula or affect how well it works.

Watch Out for Fake “Eco” Labels

Not all “eco tablets” are created equal. Some brands still sneak in synthetic fragrances, dyes, or non-compostable wrappers. Always check the ingredients list and packaging details. A truly sustainable option should be:

• Free of SLS, parabens, and artificial fragrance
• Packaged in compostable or recyclable materials
• Transparent about their sourcing and certifications

Try a Starter Set Before Committing

If you’re not sure where to start, look for a starter kit that includes one bottle and a few sample tablets. That way, you can test how it fits into your routine before stocking up — no pressure, no waste.

Leave the Bottle in Sight (You’ll Actually Use It More)

One final tip: if you leave your beautiful glass spray bottle out on the counter instead of hiding it under the sink, you’ll actually reach for it more often. Cleaning becomes less of a chore when your tools feel intentional and aesthetic.

Final Thoughts on Using Plastic-Free Cleaner Tablets

If you’ve ever wondered whether those tiny, dissolvable tablets are more than just a trend, here’s your answer: yes, they work, and yes, they’re better for you, your home, and the planet. Contrary to traditional spray cleaners packed with harsh chemicals and single-use plastic, eco-friendly cleaning tablets offer a smarter, safer way to clean. They’re non-toxic, refillable, and come in biodegradable or compostable packaging, making them a clear winner for anyone trying to cut back on waste. With options like all-purpose, glass, and kitchen-specific cleaning tablets, there’s something for every surface. And the best part? You can make your own cleaner in minutes — just add water, wait, and you’re ready to go.

I’ve tried several brands over the last year, and I’m happy to say there are now many sustainable cleaning solutions that are both effective and beautiful to use.

So if you’re still on the fence, start with one area (like the kitchen), and see for yourself. You’ll be amazed at how well these zero-waste multi-purpose cleaner tablets perform, without sacrificing cleanliness or convenience.
