However, when determining how to clean an aluminium pressure cooker, be aware that repeated and excessive use of vinegar can cause nasty staining to the metal, so exercise care and restraint when using this method, ensuring that the vinegar is well rinsed out after cleaning. It’s also a good idea to test a small amount of the vinegar solution on an inconspicuous area of your appliance first to check there is no adverse reaction.

Alternatively, a baking soda solution or paste can be used. Leave it to stand in the cooker for several hours then, use a sponge, cloth, or plastic scourer to scrub it clean.
