About us

Brothers in Business — From Squeegees to Science

We’re Craig and Chris — brothers, business partners, and lifelong collaborators. Our journey started in 2012, high up on the ladders of Argyll and Bute in West Scotland, where we launched our first window cleaning business. What began as a local operation quickly grew into one of the largest individually owned cleaning companies in Scotland.

Driven by hard work, a bit of rain (okay, a lot of rain), and a shared entrepreneurial spirit, we built our reputation on quality, consistency, and getting the job done right. Along the way, we gained deep insight into the tools and materials that really make a difference in the window cleaning industry.

That knowledge — paired with a desire to give fellow professionals a better option — led to the creation of Deionise.com. We set out to provide a product that we wished we had when we were building our business: high-performance, low-cost water purification resin that doesn't compromise on quality.

Today, Deionise.com delivers some of the highest quality and most affordable resin in the UK, built on over a decade of hands-on experience. We’re proud to support window cleaners, just like we once were, with a product they can trust — from people who’ve been there.

Thanks for stopping by — we’re glad you’re here.
