The short answer
Why Dry Cleaning Comes First
Soot is fine, oily, and sticky. If you spray water or glass cleaner directly onto it, the soot can smear into a stubborn film that is harder to remove. That is why the first pass should always be dry. Use a dry microfiber cloth, a dry sponge, or a vacuum with a soft brush attachment to lift loose particles from the glass surface.
Work from the top of the pane downward. This way, any soot that falls during cleaning does not re-soil the area you already finished. Take your time, and change to a fresh cloth as soon as one becomes visibly dirty. This simple habit keeps the soot from being pushed around rather than picked up.
Choosing the Right Cleaner
After the dry pass, pick a cleaner that cuts grease without leaving streaks. A standard glass cleaner often works, but a degreasing dish soap diluted in water can handle heavier soot. Apply the cleaner to a cloth, not directly to the glass, to control how much liquid touches the surface.
Avoid ammonia-based products if the sunroom glass has any tint or special coating, as ammonia can damage those finishes. Test any cleaner on a small, hidden corner of the glass first. If the cleaner leaves a haze or streaks, switch to a different product before doing the whole pane.

Step-By-Step Cleaning Process
Begin by removing loose soot with your dry cloth or vacuum. Then, dampen a clean cloth with your chosen cleaner and wipe the glass in a zigzag or S-shaped pattern. Flip the cloth frequently so you are always using a clean side. Finish by buffing the glass with a separate dry cloth to remove any remaining streaks.
For very stubborn spots, let the cleaner sit on the glass for a minute before wiping. Do not scrub hard, as that can scratch the glass. If the soot has baked on from heat, a soot sponge can be used gently. Rinse the glass with a clean, damp cloth afterward if your cleaner leaves residue.
When to Call the Pros
If the soot layer is thick, or if it has spread to window frames, screens, or nearby surfaces, you may need help from local water damage pros. They have industrial-grade cleaners and equipment designed for soot removal. They can also assess whether soot has gotten into the gaps around the glass or into the sunroom's structure.
A professional cleaning may be worthwhile if the soot came from a fire, because soot can be acidic and cause long-term damage if not fully removed. The pros can also clean the surrounding surfaces, like upholstery or carpets, that may have soot residue. If you live in Layton, you can search for local water damage pros who handle soot cleanup.
Preventing Future Soot Buildup
To keep soot from returning, check the source. If the soot comes from a fireplace, wood stove, or candle, make sure it is properly vented. Clean or replace air filters in your sunroom's HVAC system regularly, as soot can circulate through the air. Wipe down glass surfaces weekly with a dry cloth to catch soot before it builds up.
Consider using a high-efficiency particulate air (HEPA) filter in the sunroom to trap soot particles. If the soot comes from outside, such as from a nearby chimney, keep windows closed during heavy smoke. Regular dusting of window sills and frames also reduces the amount of soot that reaches the glass.

Can I use vinegar to clean soot off glass?
Yes, a solution of white vinegar and water can cut through soot. Mix one part vinegar with three parts water, apply with a cloth, and wipe. Test it on a small area first. Vinegar is gentle and less likely to damage coatings than harsh chemicals.
What if the soot has left a greasy film?
A greasy film means the soot has oil in it. Use a degreasing dish soap mixed with warm water. Apply with a soft cloth, let it sit briefly, then wipe. Rinse with a clean damp cloth and dry. Avoid using too much water, which can spread the grease.
Is it safe to use a razor blade on glass to remove soot?
You can use a razor blade scraper, but only with great care. Hold the blade at a low angle and pull it across the glass to scrape off soot. Test on a small area first. Mishandling can scratch the glass. A plastic scraper is a safer alternative for most people.
