Narrative:

After service; flight attendant B informed me that there is a chemical smell permeating the back galley. Flight attendant B described it as a strong; pungent; metallic smell. I agree with the description after smelling it. Flight attendant B said she feels light headed and nauseous. We both have a metallic taste in our mouths and headaches. I called the captain from the back galley and alerted the captain to the smell. He recommends that we clean the area with club soda and sanicom wipes. Flight attendant B wiped down the floors and the air vents are helping move the smell. The captain suggested asking the passengers in the back if they can smell it; but they are all currently sleeping. We have requested a cleaning crew to meet the aircraft. We also asked for maintenance and an inflight supervisor and decided to keep [catering] from opening the aft door until the smell was investigated.the plane was met by three inflight supervisors as well by aircraft tech; maintenance and captain xx who is a friend of mine and is well versed in the emergency medical I had on another [aircraft] with a toxic smell. Maintenance mopped the area well and both doors were opened for circulation. I believe the determination was made that a now discontinued form disinfecting solution was over used by contract cleaners causing a build up of excess product in the entry door vents and surrounding areas causing the toxic smell.flight attendant B was pulled from the flight and was replaced due to still feeling nauseous and light headed. The smell did not return on the next two flights.
