why does some plastic tupperware type containers still look & feel greasy after washing even with name brand soap (dawn, ajax ect.)
In: Other
Plastic is made from oil (basically, oil mixed with salt) so will bond with other oils in a process called “polymerization”.
There is an easy solution. Washing with a baking soda solution will remove the “greasy” feel, although this is not as effective if you’ve used your “tupperware” as a microwave container.
