How To Remove Smoke Haze From Glass
We clean our dirty glass in the Conservation Lab at the Corning Glass Museum, but sometimes we get some unusual requests. Recently, one of our colleagues brought us objects from his personal glass collection for home fire protection. Stains on glass artwork and food stains on baked goods may not be the most natural connection to make; however, our preservation instinct recognized that in both cases the organic material had been fired at high temperatures, so we started by revisiting an old blog on how to clean Pyrex . Soak the object for a short time. Each object’s surface and smoke residue is different, so we need to be flexible – what works for one object doesn’t necessarily work for all. For example, we used a higher concentration of sodium hydroxide to wash away soot on some sensitive surfaces so we can soak for less time and avoid harsh rubbing. soak time and/or sodium hydroxide concentration until we can remove the soot by cotton swab or light brushing. The general idea behind our process is: soak, test, evaluate, then adjust and repeat as needed.
- Protective equipment: rubber or neoprene gloves, goggles, jacket
- Faucet and distilled water
- Liquid detergent, preferably one without artificial colors or fragrances
- Sodium hydroxide or lye (we use 100% solid) *
- Plastic tub
- Soft tissue
- Synthetic brush (dissolvable natural bristles)
- Cotton gauze

Work in a well-ventilated area and wear appropriate protective equipment. Be sure to follow the manufacturer’s recommendations, see here for more details. Wear protective equipment (gloves, goggles and jacket). Test. Some adhesives and surface trimmers may be sensitive to water. Consider contacting a conservator if you suspect cleaning may damage the item. If not, test a small, inconspicuous area with a cotton swab moistened with water to make sure there are no surprises. Seeing a favorite vase transform from light paint to colorless before our eyes, while perhaps enjoyable in a different context, is perhaps not the sought-after experience here. Soap and water. While looking to switch to more aggressive cleaning methods, some items can be successfully cleaned with soap and water alone. Place the object in the basin of water and let it sit for 1-2 minutes, then gently wipe the surface with a cotton swab to check if the soot has come off. Soot can be removed from the object easily and stubborn areas can be gently removed with a brush, gauze or tissue.
- If effective, continue brushing or wiping until all soot is removed, then proceed to step 6 .
- If the effect is moderate, soak longer or move on to the next step
- If it doesn’t work, move on to the next step
A piece of glass soaked in sodium hydroxide solution. Sodium hydroxide in water. Start with a small amount—we start with about a teaspoon of 100% lye powder per gallon of water—because you can always increase the concentration. Soak for 1 minute then inspect the surface.

5. Adjust the concentration of the solution by adding half a teaspoon of lye. Soak, test, evaluate. Repeat the process until clean.
Results of our immersion tests. Increase the sodium hydroxide concentration in figures L to R6. Wash the sodium hydroxide off the surface with soap and water. Rinse with distilled water to avoid hard water stains. A little care and patience is worth it. After all, who doesn’t love clean glass and an impressive set of before and after photos? If you would like more information about our process, our findings were presented in a poster at the most recent ICOM-CC Ceramics and Glass conference in London.
