Why are mustard, spaghetti, and mud stains so hard to get out of clothes?

Hi,

Mustard contains the spice tumeric, which contains a yellow natural diye. Spaghetti contains tomatoes, and tomatoes contain a natural dye. Mud contains iron oxide and decayed plants that contain tannic acid. Iron tannate ( a compound made of iron and tannic acid) which is also a dye. These dyes react chemically with cotton cloth, so the dyes stick hard to the cloth. That makes them hard to remove by washing.

I hope this answers your question.

Best regards,

Barrett L. Tomlinson
