Tetrachloroethylene (Teodora Renata Eccleston) is the last one of the Chloroethenes House and she owns a dry cleaning business and works for both humans and Chemicals. She is mostly known as Perchloroethylene and it is very rare to see someone call her Tetrachloroethylene. As of 2023, she is 184 years old but she lies about being older to seem more professional. Her friends and customers call her Perc for short because Perchloroethylene is too long to say. Her father is living in India and it has been a long time since she saw him. She witnessed her Chlorocarbon friends being forced to "retire" by humans, Tetrachloroethylene thinks she would be next and this upsets her. She is the richest Organochloride after Vinyl Chloride.
Tetrachloroethylene was created in 1839 in France. Her early life is unknown, but it is thought that she spent her early life with Carbon Tetrachloride who introduced her to dry-cleaning later in the 20th century (around the 1940s). Tetrachloroethylene had a short career in veterinary medicine (presumably in the 1920s, right after C. Tetrachloride) and refrigeration. Tetrachloroethylene loved dry-cleaning. She allowed Trichloroethylene, who started dry-cleaning a decade before her, to work with her. Trichloroethylene saw Perchloroethylene as a rival and considered herself superior to Perchloroethylene. After Trichloroethylene lost her job in dry-cleaning, Tetrachloroethylene became more dominant in the area. There had been many other Chemicals that tried to overthrow her from dry-cleaning. Some Hydrocarbons and Propyl Bromide I attempted to replace Perchloroethylene, but none of them was as successful as she was.
Perc is a very sweet and tolerant person. Tetrachloroethylene is never seen getting angry at anything or anybody. She has a human-like personality and acts as if she has empathy. She likes talking with other Chemicals and her human customers. Tetrachloroethylene welcomes her customers with a smile. She let humans get close to her and let them touch her hair or even hug her which is not allowed usually. Despite being happy most of the time, she always looks very exhausted. Tetrachloroethylene is very obedient and accepts all customers, rarely asking questions about garments and stains. She is liked by most, if not all, customers. Some people do not like her dominating the dry-cleaning industry and claim that her work is hazardous. Perc fears that humans will force her out of this industry.
She tells everyone that she is English and over 200 years old. However, humans believed her little lie. In reality, Perchloroethylene is French and 184 years old. In contrast, C. Tetrachloride pretends to be 184 years old and fakes being French. Tetrachloroethylene is very fluent in French, Italian and German.
Tetrachloroethylene has dark blue hair, pale light skin and dark red coloured eyes that are typical of Chlorocarbons. Her hair is curled at the ends. Perc has soft makeup to make her face look more "alive and human". She is often seen either wearing her Chemical uniform or a dress resembling the human fashions of the mid-20th century. Her uniform consists of a long dark blue coat with short sleeves, a light blue cotton shirt with long sleeves, black cotton trousers and black leather boots. Her name tag reads "Tetrachloroethylene".
Just like most of the Chemicals, Tetrachloroethylene doesn't breathe except for speaking and does not blink much. Sometimes her customers notice and point it out.
Perc has a very large dry-cleaning shop which is thought to be owned by Carbon Tetrachloride previously. She is almost always inside her shop and working. The shop is portrayed differently in various artworks depicting Tetrachloroethylene and Carbon Tetrachloride. Artworks of Carbon Tet's era of ownership show it from outside as a very small shop with turquoise painted walls, a large window, a wooden door and a sign saying "Nettoyage a Sec". The shop's interior walls were painted at least three times after the acquisition by Trichloroethylene and Tetrachloroethylene.
Tetrachloroethylene is not allowed to leave the shop after several incidents of running away (often together with TCE).
