does the white tupperware beetroot keeper stain red with the beetroot?

I have some very old tuppweware that has cracked lids. When on the warranty site the numbers come up not known what can I do

I had a Tupperware container that was in back of fridge . It was moldy. I washed in some and bleach. The bowl is fine but the lid that has ridges still smell like mold. I'll need a new one. Small bowl with white lid,comes in set of 4. Where can I buy?
