Do you often find your tupperware still greasy, with streaks and grease stains even after a dishwasher cycle? It’s quite common: some food residues and sauces can be difficult to remove completely from plastic.
A few simple precautions can help you wash your food containers in the dishwasher and prevent them from becoming stained or retaining odours over time.
What are the enemies of clean Tupperware?
- Grease residues: oil, butter and other condiments can stick more easily to plastic surfaces, making them harder to remove completely.
- Food stains: tomato, sauces and spices can leave streaks and stubborn stains on containers.
- Washing mistakes: choosing the wrong programme or placing containers incorrectly can affect the final result.
Simple steps to wash food containers in the dishwasher
Before, during and after washing, there are a few simple things you can do to help keep your containers clean and residue-free.
Prepare your containers for washing
First, check the label to make sure your containers are dishwasher-safe. Remove any excess food and grease residues using a napkin or a sheet of kitchen roll. Finally, separate the containers from their lids to allow water to reach every surface.
Position your containers correctly
It may seem like a small detail, but arranging your containers correctly allows water to reach every surface and helps achieve more effective cleaning. Here are a few tips:
- Place containers securely, making sure they won’t tip over during the wash.
- Avoid stacking them or overloading the rack.
- Make sure they don’t block other dishes and leave enough space for water to circulate freely.

Choose the right programme
Not all washing programmes are the same: choosing the one that best suits the dishes you’re washing can make all the difference.
When it comes to removing oil and grease residues, water temperature also plays an important role. Heat helps loosen stubborn dirt, so for particularly dirty containers, choose programmes with higher temperatures.

Some tips for tackling stubborn stains
Even after a proper wash, some containers may still have stubborn stains or lingering odours.
For stains caused by tomato, curry and other highly pigmented foods, try soaking the container in warm water with washing-up liquid, following the manufacturer’s instructions. Avoid abrasive sponges or overly harsh products, as they could damage the surface.
To get rid of lingering odours, remember to wash the lids thoroughly too, paying particular attention to any grooves and seals where food residues can build up.
Finally, allow the containers to dry completely before putting them away and, if possible, avoid closing them with their lids straight away.
