Eco-Friendly Dry Cleaning II

Overview

Led by Mr. Yoshiaki Tanaka, Cleaning Edoya is a cleaning business based in Kazuno City, Akita Prefecture, Japan. 
The company is strongly committed to using environmentally friendly methods and materials. 
Mr. Tanaka’s journey began with a focus on synthetic detergents, which led to significant health problems. 
Over time, his dedication to eco-conscious practices evolved, leading him to adopt natural cleaning methods using soap and EM Technology, as well as natural materials like tapioca starch.
Edoya’s cleaning practices aim to preserve the environment and local culture.

Health issues from chemicals led him to switch to natural materials.
Initially, Mr. Tanaka focused on synthetic detergents and water softening chemicals, seeking the most effective cleaning solutions. However, prolonged exposure led to severe physical health issues. His skin deteriorated so badly that the bones in his fingers became visible. This prompted a reevaluation of his approach to cleaning, as he realized he couldn’t continue like this.

His past experiences with eco-friendly principles, such as his Boy Scout upbringing, informed his environmental awareness and his eventual shift towards natural cleaning agents. After remembering his father’s use of shark oil soap, he discovered the natural Shabondama Soap, which marked the beginning of his commitment to more sustainable cleaning methods.

Environmentally Friendly Methods

By integrating EM Technology with natural agents like Shabondama Soap and tapioca starch, Mr. Tanaka enhanced the effectiveness of his cleaning methods. After researching how to apply EM solution in dry cleaning, he found that combining it with soap in a specific ratio improved cleaning performance. He also discovered that using EM solution with starch agents, particularly tapioca starch, produced excellent results.

Traditionally used as a stiffening agent, tapioca starch became a key part of his process. When mixed with EM solution, the starch spreads more evenly and rinses off more easily, acting as a protective coating that prevents dirt from adhering to fabric. This eco-friendly method is gentle on both clothing and the environment.

 

Tapioca starch is originally a food product, so it is naturally safe for the skin.

Effects and Results

The combination of Shabondama Soap and EM Technology is both effective and safe, with no harmful effects on skin or clothing. Customers appreciate the concept of a cleaning service that uses only natural, safe ingredients.
Mr. Tanaka’s emphasis on protecting clothes and extending their lifespan reflects his broader eco-friendly values.
“Our goal is to provide low-impact cleaning,” he says. “That means something gentle on the clothes, the wearer, the Earth, and us, the cleaners."

Moreover, Mr. Tanaka’s efforts extend beyond cleaning to support the local community by preserving traditional clothing, such as cleaning Yukata (a lighter fabric kimono for casual events) for local festivals, an important part of Kazuno City’s cultural heritage. His work demonstrates his dedication to sustainability and preserving regional traditions.
