Cleaning Door Glass Properly

Short answer
Clean composite door glass with a standard glass cleaner or warm soapy water and a soft, lint-free cloth, working gently around any decorative leadwork rather than scrubbing it directly. Avoid ammonia-heavy or abrasive cleaners on leaded designs, and keep excess liquid away from the surrounding frame and seals.
The glazed panel in a composite door is often its focal point, particularly with decorative or leaded designs, so it's worth cleaning it properly. The approach is simple, but a couple of details matter more than they might seem.
The basic method
A standard glass cleaner applied with a soft, lint-free cloth works well for plain glazing, or use warm water with a little washing-up liquid if you prefer to avoid chemical sprays. Wipe in a consistent direction and finish with a dry cloth to avoid streaking.
Decorative and leaded glass
Where a design includes decorative lead or bar detailing, clean gently around it rather than scrubbing directly across the lines, as repeated abrasive pressure can eventually lift or dull the leadwork. A soft cloth with minimal pressure is all that's needed.

What to avoid near the frame
Keep glass cleaner away from excessive contact with the surrounding frame and seals, as some formulations can affect sealant over repeated use. Spray onto the cloth rather than directly onto the glass if you're working close to the edges.
Condensation between panes
If you notice condensation forming between the panes of a sealed glazed unit rather than on the surface, this indicates the seal has failed and cleaning won't resolve it. This is a job for a professional to assess, and may be covered under your guarantee depending on the cause.
Frequently asked questions
Can I use vinegar to clean my door glass?
We'd avoid it, particularly on decorative leaded glass, where the acidity can affect metal detailing over repeated use. A proper glass cleaner or mild soapy water is a safer, equally effective choice.
How do I clean between decorative bars on the glass?
Use a soft cloth and gentle pressure, cleaning along the line of the bars rather than across them. A soft-bristled brush can help reach tight corners without needing to press hard against the leadwork.
Why does my door glass look misty even after cleaning?
Misting that stays after cleaning, especially between two panes, usually means the sealed unit has failed internally rather than being a surface cleaning issue. A professional can confirm this and advise on replacement.
How often should I clean my door glass?
Every few weeks alongside your general door cleaning routine is plenty for most homes, though doors in high-traffic entrances or exposed to more weather may benefit from a quick wipe more frequently.
