Actor Yoon Si-yoon has newly joined the cast of the SBS entertainment program “My Little Old Boy.” While he was a familiar face during his time on the KBS entertainment program “2 Days & 1 Night,” he has since been seen only occasionally on variety shows, making him a rare guest. This is the first time he has not only appeared by himself for a full hour but also revealed his private life, including his home. For this reason, he is garnering a great deal of attention. The episode showcased his personality with nicknames like “Alarm King,” “Planning King,” “Cleaning King,” “Organizing King,” “Car Wash King,” “Self-Control King,” and “Effort King”—traits rarely seen in ordinary people. Among these, the car washing scene was particularly impressive. Yoon Si-yoon: “Washing my car helps me feel stable and good. It’s like I’m having a conversation with my car while handling this big machine. I go to wash my car once a week, without fail.” Yoon Si-yoon drives his car to a self-service car wash. As soon as he arrives, he puts on a jumpsuit specifically for car washing. His shopping bag is filled with car cleaning supplies, the sheer number of which hints at his expertise. Over the jumpsuit, he wears another apron for car washing. He even puts on headphones to block out any noise that might interfere with the task. He is truly serious about washing his car. Seeing this, MC Seo Jang-hoon remarks, “He’s completely sincere in everything he does.” He starts taking out his car washing supplies, and they seem endless. As soon as they are out, he arranges them in perfect order. The items include cleaning brushes, a compression sprayer, pre-wash detergent, car shampoo, tire cleaner, tar remover, an oil film remover, car polish, a second car polish, an interior coating agent, a leather moisturizer, tire shine, a microfiber towel, and a second microfiber towel. He meticulously organizes this vast array of supplies by purpose. Now, it’s time to wash the car. He starts by spraying high-pressure water, maintaining a 45-degree angle and keeping the nozzle from touching the car. He exudes the aura of a professional. The dirt starts to come off under the high-pressure water. He washes the tires with a circular, rolling motion. At this point, the celebrity mothers on the show’s panel start to comment. When singer Kim Hee-chul’s mother says, “He looks like a car wash employee,” actor Lee Dong-gun’s mother adds, “I’d believe it if you told me he was.” Next, he sprays a tire cleaner to remove contaminants and scrubs the tires with a dedicated brush. He has two tire brushes: a thin one for detailed work, capable of cleaning inside small holes, and a wider one for cleaning the entire surface. He is truly dedicated to his tires. Watching this, MC Seo Jang-hoon comments, “Even if you took it to a professional car wash, they wouldn’t do it that thoroughly.” Yoon Si-yoon says, “Pre-wash. Let’s let the dirt soak,” as he begins the process of removing contaminants and soaking the ingrained dirt. He then sprays snow foam to further loosen the dirt with a fine-foamed detergent. With a skillful hand, he evenly covers the car in a thick layer of foam. To prepare the car shampoo, he adds high-pressure water to the detergent, and the bucket quickly fills with suds. He then shampoos the car by hand, rather than using a machine, to wash off the dirt that has been loosened by the snow foam. He meticulously cleans every nook and cranny, even inside the fuel filler door. MC Seo Jang-hoon exclaims, “I’ve never seen anyone clean the inside of the fuel filler door before.” Yoon Si-yoon: “I think I just like cleaning. When I see something dirty, I get really excited if I know I can clean it. I love it. The process of steaming it with hot water, melting the grime, and scrubbing it until it’s clean—I really enjoy that.” For him, washing his car is the ultimate healing time. Now it’s time to rinse. The deep-seated dirt is washed away, providing a sense of relief. He has a happy expression on his face, even as he sweats profusely. Next is drying. Using a special microfiber towel for cars, he pulls it across the surface in one smooth motion without rubbing, and the water disappears in an instant. The surface is left spotless after this single pass. A professional tool, an oil film remover, even makes an appearance to get rid of the greasy film on the windows. MC Seo Jang-hoon says, “He’s going to be so sore when he gets home. He’s working too hard,” to which the celebrity mothers unanimously agree, “He’s going to catch a cold from exhaustion.” Finally, the last step of the car wash: polishing. He sprays the polish and wipes it with a microfiber cloth. After he’s done, he places a paper cup on the car’s bumper to see if it slides off. He is satisfied when the cup glides smoothly. The two-hour car wash is complete. Considering it took two hours just for the exterior, the interior would likely take another two hours. Although the car is 12 years old, it looks brand new thanks to his meticulous care. By the time he finishes, evening has fallen. It’s 8 PM. As soon as he gets home, he takes the car washing supplies into the bathroom and, without a moment’s rest, immediately starts cleaning them. He even washes the detergent containers. The celebrity mothers watch with concern, wondering when he ever rests. The cleaning of the car washing supplies is finished. But then, he takes out bleach and other cleaning supplies again. Now, he starts cleaning the bathroom, which got dirty from cleaning the car wash equipment. From the mirror to the toilet, he doesn’t stop, sweating profusely. There’s no rest until the cleaning is done. This prompts MC Shin Dong-yup to remark, “Now I see why Yoon Si-yoon’s mother can’t
