Looking for the best window cleaning solution? With so many DIY tips and commercial window cleaning products out there, which one is actually the best at getting windows clean and streak-free? 

Of course, part of getting your windows spotless is in the technique (more on that in our guide to cleaning windows). Wiping off whatever you're using quickly, in a downward motion, rather than going around in circles, is key. But the right kind of product also matters. 

We do like giving our windows a good deep clean at least twice a year at Real Homes, and, more often than not, we don't have a specially formulated window cleaner to hand. What we do really enjoy using is...(drumroll please) Ecover washing-up liquid – especially the Lemon & Aloe Vera type, although any type will do. 

Yes, the best-selling plant-based washing-up liquid is great at tackling built-up dirt on windows, and it's easy to wash off without leaving any streaks too. We think that it works so well because it doesn't foam too much and doesn't contain too many ingredients that can leave a residue. Simply apply the product with a damp cloth, leave on for five minutes, wipe it off and hey presto, shiny windows.
