What You’ll Need
- Non-scratch scrub pad for glass bakeware
- Microfiber cleaning cloth for glassware
- Glass polishing pad for cloudy Pyrex
- Eraser sponge (magic eraser) for glass cleaning
- Nylon bristle bottle brush for bakeware cleaning
Before You Start
Inspect the Pyrex for cracks or chips before cleaning. Do not soak hot glass in cold water, which can cause breakage. Use warm, soapy water and avoid harsh chemicals that can degrade the glass finish. Allow the dish to cool to room temperature if it’s recently been heated. This process typically takes 10–20 minutes of prep time and 15–30 minutes for cleaning, depending on the level of cloudiness.
Cautions: Do not use metal utensils or abrasive scouring powders. Wear gloves if your hands are sensitive to cleaning solutions. Work on a stable surface to prevent slips and accidents.
Step-By-Step: How To Clean Cloudy Pyrex Glass
- Fill the sink with warm, soapy water and submerge the Pyrex piece to loosen grease and baked-on residues.
- Wipe the interior and exterior with a microfiber cleaning cloth for glassware to remove loose grime.
- Apply a small amount of dish soap to the non-scratch scrub pad for glass bakeware and gently scour the cloudy areas in a circular motion.

- For stubborn spots, use the eraser sponge (magic eraser) for glass cleaning in soft, controlled presses. Avoid excessive moisture; a damp sponge works best.
- Rinse with warm water to remove soap and residue. Inspect for remaining haze and repeat steps 3–5 as needed.
- Use the nylon bristle bottle brush for bakeware cleaning to reach corners and handles without scratching.
- Dry thoroughly with a clean microfiber cloth to prevent water spots and streaks.
