How to get the sticky feeling off of tupperware?

soak them in white vinegar and baking soda

Use a paste of water and Baking soda.

Mix baking soda and coconut oil to make a paste. Apply on the sticky area and leave for about an hour. Alternatively, you could use mayonnaise and leave for half an hour before cleaning.

Goo gone maybe?

I have used plain baking soda . Wet Tupperware item. Take a small amount of soda on a damp cloth, repeat as needed. Work all over the surface of the bowl, etc. Wash as usual. Love Tupperware. I do not put my 60 yr old Tupperware in the dishwasher.

Sticky as in grease or label? Dawn normally cuts greasy plastic pretty well, but if that doesn't work a mixture of lemon essential oil and baking soda works great. You'd only need a few drops of oil in a tablespoon or so of baking powder and slowly add water to make a paste rub on and rinse off immediatly and repeat if necessary

Once I got a dishwasher, the 'sticky stuff' came off. However, before the dishwasher, I used baking soda and warm water.
