It’s a good idea to retire a container when you notice:

• Chips, cracks, or deep scratches in the glass that could spread under heat or stress.
• Warped or loose lids that no longer seal or keep popping off.
• Persistent stains or odors in lids after cleaning and airing out.
• Cloudy or etched glass that stays rough even after washing.
• Missing or loose gasket parts on airtight styles.

If the glass is fine but the lid is tired, replacement lids are available on Walmart.com—match by size/shape or the code on the lid. Avoid using damaged glass in ovens or microwaves. For disposal, follow local guidelines and handle broken pieces carefully.

Use will vary by item, so start by checking the product page for specific care icons and instructions. In general:

• Oven: Use only dishes labeled oven-safe. Remove plastic lids before baking.
• Microwave: Vent lids only if they’re marked microwave-safe. Shorter heat cycles can help.
• Avoid thermal shock: Don’t place hot glass on a cold surface or add cold liquids to hot glass.
• Skip direct heat: Avoid broilers, stovetops, and exposed heating elements unless the listing says otherwise.
• Safe landing: Set hot dishes on a dry towel or rack.

These tips can help extend the life of your containers, but always follow the directions on the specific item.

Matching lids is easier when you use the codes and shapes:

• Check the code stamped inside the lid (for example, 7200‑PC, 7201‑PC, 7210‑PC). Order replacements with the same code.
• Match shape and capacity: Round lids fit round bowls; rectangular lids fit rectangular dishes. 1‑cup, 2‑cup, 3‑cup, 4‑cup, and 6/7‑cup typically use different lids.
• Color can vary, but size and code determine fit.
• Confirm measurements on the product page if you’re unsure.

You’ll find single lids and multi-size lid bundles on Walmart.com, which can be handy if you own a mix of containers.

Pick sizes based on what you store most:

• 1‑cup: Sauces, dips, small snacks.
• 2‑cup: Cut fruit, sides, smaller leftovers.
• 3–4‑cup: Single meals, salads, meal‑prep portions.
• 6–7‑cup: Family‑size leftovers, batch cooking, baked dishes.
• Round vs. rectangular: Round is great for soups and mixing; rectangular stacks tightly and fits shelves and casseroles well.
• Divided containers keep foods separate for lunches.
• Airtight lids can help reduce leaks and contain odors.

Filter by size, shape, and lid type on Walmart.com to build a set that fits your routine.

A few easy habits can help your set last:

• Glass: Most pieces are dishwasher-friendly; avoid abrasive pads. For stuck-on bits, soak with warm water and a little baking soda.
• Lids: Hand-wash or top-rack to help prevent warping; avoid high-heat drying cycles unless noted on the listing.
• Odors and stains: A short baking soda soak, then air-dry with lids off, may help.
• Storage: Nest bowls by size and store lids upright or clipped loosely for airflow.
• Routine checks: Inspect for cracks, cloudiness, or loose seals and replace parts as needed.

Always follow the care guidance shown on each product page.
