Why
Prep Solutions by Progressive containers are typically made of Tritan copolyester (a BPA-free plastic) for the body and polypropylene with a silicone gasket for the lid. Tritan is generally dishwasher safe on the top rack, as it resists warping and clouding up to about 90°C. However, the lid's silicone gasket can degrade over time due to high heat and alkaline detergent, losing its seal and causing leaks. The manufacturer often recommends hand washing the lid to preserve the gasket's integrity. Repeated machine washing may also cause the lid's plastic to warp or the gasket to swell, leading to poor fit. The body is more durable but can become etched or cloudy after many cycles if exposed to high heat or harsh detergents.
How do you wash Prep Solutions by Progressive?
- Disassemble the lid by pulling out the silicone gasket.
- Hand wash the lid and gasket in warm soapy water, using a soft sponge.
- Rinse thoroughly and air dry completely before reassembling.
- Place the Tritan body on the top rack of the dishwasher, away from the heating element.
- Use a mild detergent and avoid high-temperature cycles or sanitize settings.
- After the cycle, remove the body promptly and let it air dry.
- Reassemble the lid only after all parts are fully dry.
What happens if you put Prep Solutions by Progressive in the dishwasher?
If you put the entire container in the dishwasher, after one wash you may not notice immediate damage. However, after repeated washes (5-10 cycles), the silicone gasket may become sticky, swollen, or lose its shape, causing the lid to no longer seal tightly. The lid's plastic may also warp slightly, making it difficult to snap on. The Tritan body may develop a slight haze or etching, especially if washed on the bottom rack or with high heat. These changes are primarily cosmetic for the body but functional for the lid and gasket—leaks can occur, reducing the container's usefulness. Over time, the gasket may need replacement. The damage is cumulative and permanent.
Frequently asked questions
- What water temperature can the Tritan body withstand?
- Tritan copolyester can typically withstand temperatures up to 100°C (212°F) without warping, but prolonged exposure above 90°C may cause slight deformation. Dishwasher top-rack temperatures are usually safe.
- Will the lid's silicone gasket peel or crack over time?
- Yes, with repeated dishwasher exposure, the silicone gasket can degrade, becoming sticky, swollen, or cracked. Hand washing extends its life significantly.
- Can the container be used in the microwave or freezer?
- The Tritan body is generally microwave-safe (without the lid) and freezer-safe. However, the lid may not be microwave-safe due to the gasket. Always check the manufacturer's instructions.
- How often should I replace the gasket?
- If hand washed, the gasket can last for years. If machine washed, it may need replacement every 6-12 months once it loses its seal or becomes sticky.
