A Marvellously Clear View Without the Caustic Drama
If you've ever found yourself squinting through grimy smudges wondering if your window doubled as a modern art installation, well, you’re not alone. Our EcoGlass Window Cleaner is your slightly heroic partner in the noble quest for streak-free brilliance—no harsh chemicals, no environmental guilt, and not a single whiff of ammonia.
Why Choose Our EcoGlass Window Cleaner?
- Natural Formula: Made with delightfully safe ingredients that are friendly to noses, children, houseplants, and even your dog’s opinion of you.
- Streak-Free Shine: Because clouds belong in the sky, not on your windows.
- Concentrated Value: A clever little potion you mix with water, stretching further than your last pay packet.
- Gentle Yet Potent: Tackles grub and fingerprints like a pro, but won’t offend anyone’s allergies.
- Robot-Ready: Fully compatible with window cleaning bots, should you be fortunate enough to own such mechanical wizardry.
Product Details:
- Preparation: Mix 100 ml of cleaner with 5 litres of water for regular use. For tougher grime, channel your inner rebel and increase the ratio.
- How to Use: Apply with a sponge or microfiber cloth—wipe from top to bottom like someone who knows what they’re doing.
- Drying: Follow with a trusty squeegee and perhaps a chamois if you’re feeling swanky.
- Best conditions: Clean when it's cool and shady. Not ideal: direct sunlight, wind, or dramatic weather of any kind.
- Aftercare Tip: For longer-lasting sparkle, consider pairing with our Liquid Skin shield. Very Sherlock and Watson, the two of them.
Safety Note: Non-toxic and gentle, but best kept out of reach from curious tots or pets with ambitions of window-cleaning greatness.
Give your home the gift of gloriously clean glass. Your windows will thank you. Probably silently, but still. Add to cart while you're here, before the sun returns and exposes everything.
SHIPPING + RETURNS
THE RATHER IMPORTANT BITS
This rather lovely piece ships directly from our brand partner - we work with independent brands who are absolutely brilliant and work frightfully hard to create beautiful things.
SHIPPING DESTINATIONS
Now, here's the thing - our wonderful brand partners ship to lots of different places, but not all of them can ship worldwide.
Some are brilliant at international shipping, others prefer to keep things closer to home.
At checkout, you'll see exactly where this particular brand can send your goodies.
We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!
RETURNS
You have 14 days to return items.
Now, we absolutely adore our brand partners - they work incredibly hard and we do try to support them as much as we possibly can. So I'm rather afraid we have to pass the return postage costs back to you. Frightfully sorry about that!
🌍 PLEASE CHOOSE THOUGHTFULLY:
Our wonderful partners put their hearts into everything they make.
Ordering multiple sizes to try at home is rather hard on our planet and makes things jolly difficult for these brilliant independent creators.
When in doubt, do ask us first!
The brands we work with all have a chat option, and they love to chat!
PAYMENT
We're frightfully modern and accept all the usual suspects:
Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay
SECURE AS HOUSES
Everything's properly encrypted and secure - your details are safer than the Crown Jewels!
All prices in lovely British pounds £ GBP, though international chaps will see converted prices.
Any payment pickle? We're here to help sort things out! Contact us

We are Sostter
We met as children. Grew up a few streets apart. Built dens, rode bikes, and eventually — built Sostter.
It started with a shared love of objects that meant something…things with a past, or at least a purpose.
Now, Sostter is our grown-up version of a treasure hunt: a space where design meets storytelling.
We curate independent brands, one-of-a-kind finds, and everyday essentials with character.
Giving Back
We’re proud to support Sutton Night Watch, a grassroots UK charity making a real difference in the lives of those facing homelessness. Through regular donations of stock, supplies, and essentials, we back their mission to offer warmth, dignity, and practical help to anyone in need — right where it matters most.
