Why
The Aeropress is made primarily of BPA-free polypropylene (body and plunger) and silicone (seal). Polypropylene has a melting point around 130°C (266°F), which is above typical dishwasher temperatures (max ~70°C/160°F), so the body can withstand the heat. However, the silicone seal can degrade over time due to the combination of heat and alkaline detergent, leading to loss of elasticity and eventual cracking. The manufacturer, Aeropress, explicitly states that the plunger and seal should not be placed in the dishwasher, while the chamber (body) is top-rack safe. The main failure mode for the silicone seal is seal degradation (hardening, cracking), and for the body, repeated high-heat cycles may cause minor warping or stress cracking, though rare. The printed markings on the body may also fade or peel over time with frequent dishwasher use.
How do you wash Aeropress Coffee Maker?
- Disassemble the Aeropress by removing the plunger and cap.
- Push out the silicone seal from the plunger.
- Hand wash the plunger, silicone seal, and cap in warm soapy water using a soft sponge.
- Rinse thoroughly to remove all soap residue.
- The chamber (body) can be placed on the top rack of the dishwasher, but hand washing is recommended for longevity.
- Air dry all parts completely before reassembly.
- Store with the plunger pushed slightly into the chamber to maintain seal shape.
What happens if you put Aeropress Coffee Maker in the dishwasher?
If you put the entire Aeropress in the dishwasher, the silicone seal will be the first to fail. After one wash, you may notice the seal feels slightly stiffer. After repeated washes (10-20 cycles), the seal will harden, crack, and lose its ability to create a proper seal, causing leaks during brewing. The plunger itself may warp slightly, making it harder to press. The chamber (body) is more resilient but may develop stress cracks around the bottom edge after many cycles. The printed markings (e.g., measurement lines) will fade and peel, reducing readability. The damage is initially cosmetic but becomes functional when the seal fails, requiring replacement. The body and plunger may still be usable, but the overall performance degrades.
Frequently asked questions
- What water temperature can the Aeropress withstand?
- The Aeropress is designed for water up to 100°C (212°F), as it is used for brewing coffee. The polypropylene body can handle boiling water without warping, but the silicone seal may degrade faster with very hot water.
- Will the coating peel over time?
- The Aeropress has no coating; it is made of solid polypropylene and silicone. However, the printed markings may peel or fade with dishwasher use or abrasive cleaning.
- How often should the silicone seal be replaced?
- Aeropress recommends replacing the silicone seal every 6-12 months with regular use, or sooner if it becomes hard or cracked. Hand washing extends its life.
