We trialled a new eco-friendly cleaning solution at 20 sites and here’s what happened…

At CleanKing we’re always looking for ways to improve.
That’s why we recently trialled a new product across 20 client sites.
Windmill Refill Synergy All Purpose Cleaner & Sanitiser is an eco-conscious cleaning solution that’s tough on grime, gentle on the environment, and safe to use across a wide range of spaces and surfaces.
The response from our team and clients was immediate and enthusiastic!
“It smells so good I might start wearing it as aftershave” Ant joked
“There’s nothing left behind… No streaks… It just makes everything so clean!” said Area Manager Sam
One client who had been struggling with lingering odours in her site’s toilets was particularly impressed. She wasn’t hoping for a clean that smelled good, as this area had been a persistent problem for some time. But after a visit from Sam using the new product, she said:
“I can’t believe it. Not only is the smell gone… it actually smells nice!”
We’d love to say every site and client is ready to go fully eco. We know that for most, the desire is there, but with the reality of having budgets to meet, premium green products can be dismissed. That’s why we’ve chosen to integrate Windmill Refill Synergy into our wider cleaning toolkit. It strikes a rare balance between being eco-conscious and budget-friendly. It’s one of the most practical upgrades we’ve taken on.
What impressed us most wasn’t just the performance, but the versatility. This one solution does it all. It cleans and sanitises glass and windows, mirrors, carpets, hard floors, and surfaces. It even includes a fresh-scented air freshener. It fits easily into our current setup, and our teams took to it straight away. Clients have commented on the results being visibly cleaner with a noticeably fresher feel.
It’s a small shift, but it reflects a larger goal: Leading the industry forward with smarter, cleaner, more considered choices.
