For 18 to 20 hours each day, over 7,000 people flog, scrub, dye and bleach clothes on concrete wash pens, dry them on ropes, neatly press them and transport the garments to different parts of the city. Over one lakh (100,000) clothes are washed each day. Some of the wealthier dhobis have given up on manual cleaning and have now installed large mechanical washing and drying machines. The dhobis collect clothes from all corners of the city, from Colaba to Virar.
