Detailed Solution

These days, hydrogen peroxide (H₂O₂) is used for the purpose of bleaching clothes in the process of laundry, which gives better results and makes use of lesser amount of water.
Tetra chloroethene (Cl₂C=CCl₂) was earlier used as solvent for dry cleaning.
The compound contaminates the ground water and is also a suspected carcinogen.
The process using this compound is now being replaced by a process, where liquefied carbon dioxide, with a suitable detergent is used.
Replacement of halogenated solvent by liquid CO₂will result in less harm to ground water.
