In workplaces with high radiation levels, such as hospital radiology departments, the use of lead glass is particularly important. Therefore, keeping lead glass clean is an essential part of the job.

Lead glass manufacturers recommend paying special attention to cleaning methods, as improper cleaning can damage the lead glass and shorten its lifespan.

Lead glass is typically cleaned using a strong acidic oxidizing agent. This strong acidic oxidizing agent solution is prepared from potassium dichromate and concentrated sulfuric acid. Potassium dichromate has a strong oxidizing ability in acidic solutions and is only slightly corrosive to glassware, making it widely used for cleaning lead glass.

When using this solution, always ensure that it does not splash onto your body to avoid burning clothing and damaging your skin. When pouring the solution into the equipment to be cleaned, ensure that the inner walls of the equipment are completely submerged, let it stand for a moment, and then pour the solution back into the solution bottle.

After initially rinsing the cleaned equipment with a small amount of water, never pour the wastewater into the sink or drain, as this will corrode the sink or drain. Wastewater should be poured into waste liquid tanks for centralized treatment.

Alkaline cleaning solutions can also be used when cleaning lead glass. Alkaline cleaning solutions can be used to clean lead glass stained with oil. When removing lead glass from alkaline cleaning solutions, latex gloves should be worn to avoid skin burns.

If slight mold spots appear on the surface of the lead glass due to improper protection, they can be removed by wiping with a cotton ball soaked in anhydrous alcohol.
