Best window cleaning method – simple steps for crystal clear glass

Got dirty windows and no idea where to start? You’re not alone. Most people waste hours with cheap sprays that leave streaks, or they call a pro and pay a lot. The good news? You can get a professional shine at home with a few basic tools, the right solution, and a quick method that works on any glass.

First, gather what you need: a bucket, warm water, a mild dish soap (like Dawn), a microfiber cloth, a good quality squeegee, and a spray bottle. If you prefer a vinegar mix, add one part white vinegar to three parts water – it cuts grime and dries fast. Avoid harsh chemicals; they can damage the seal and leave residue.

DIY mix that actually works

Mix 1‑2 teaspoons of dish soap into a gallon of warm water. The soap breaks down greasy film without creating a foamy mess that clouds the glass. For extra shine, add a splash of rubbing alcohol – it helps the glass dry faster and reduces streaks.

Dip a clean microfiber cloth into the solution, wring it out so it’s damp, not soaking, and wipe the pane in a top‑to‑bottom motion. This removes dust and the bulk of the dirt. Next, grab your squeegee. Start at the top corner, pull the squeegee across the glass in a smooth, straight line, and wipe the blade with a dry cloth after each pass. Overlap each stroke by about an inch to avoid streaks.

When you reach the bottom, you’ll see a clear, dry line where the squeegee finished. Use a fresh microfiber cloth to dry the edges and any drips. If you notice a stubborn spot, spray a little undiluted vinegar directly onto it, let it sit for 30 seconds, then wipe away.

When to call a pro

Even the best DIY method has limits. If you have hard‑water stains that won’t budge, a professional-grade cleaner with a chelating agent can save you time. Multi‑story homes or windows reachable only by ladder also merit a pro’s touch – safety first.

Professional cleaners often use pure‑water systems that remove minerals and leave no residue. They also bring extension poles and specialty blades for tough corners. A typical service in the UK costs between £30‑£60 per hour, but many offer a flat rate for a full‑house job, which can be cheaper than multiple DIY attempts.

Bottom line: for most everyday windows, the DIY mix plus a squeegee gives you a streak‑free finish in under ten minutes per pane. Keep your tools clean, work in the shade, and repeat the process every few months to prevent buildup. When the grime gets too stubborn or the job is risky, a professional service is worth the investment.

Now you have a clear plan, a few simple ingredients, and a method that rivals the pros. Give it a try on one window, then watch the whole house sparkle without breaking the bank.
