Stains Of rust on clothes can be removed by -

  • A.H2O2
  • B.Petrol
  • C.Alcohol
  • D.Oxalic acid

Answer: D

Rust stains are removed with oxalic acid.

It reduces the insoluble iron(III) of the rust and forms a soluble complex with it, so the stain washes out of the fabric. Lemon juice and salt work more slowly by the same principle.
