Some vehicles need a quick wash, while others need a miracle to look brand new again. This 2019 Chevrolet Blazer featured in a recent detailing video clearly belongs to the second category, arriving in a state so bad that the detailer admitted he didn't even want to know what some of the interior stains were.The video, posted by The Detail Geek on YouTube, showed the Blazer come in with over 127,000 km (about 79,000 miles) on the odometer, with most of those miles driven on gravel roads. The owner lives out of town and drives on unpaved roads regularly, and the SUV wore every mile of that in the form of caked-on dirt, swirled and scratched paint, and rock chips from years of gravel exposure.It did not take too long for the scale of the job to become evident. Just a few passes with the pressure washer revealed damaged paint underneath the grime, while the channel around the tailgate was found completely stuffed with compacted dirt. The wheel barrels held roughly an inch of solid, caked-on mud, requiring the detailer to spray from multiple angles just to break it all loose.AdvertisementAdvertisementThe front end of the SUV hadn't fared any better, coated in bug residue that appeared to have been baking on for an entire summer. It was clear that a pressure washer alone would not do the job. Thus, the detailer had to turn to a dedicated bug remover to fully clear the front bumper and hood. What followed was a satisfying foam wash that brought out the shiny black paint that had remained hidden under the grime for so long.Image Credit: The Detail Geek / YouTubeThe Interior Told an Even Worse StoryThe interior of the Blazer made the filthy exterior from before the wash look immaculate, which was a testament to the condition of nearly every surface inside the SUV. The floor mats were, in the detailer's words, "insanely dirty," and once the front seats were pulled to access the rear carpet sections, he called them some of the dirtiest he had ever encountered.The carpet fibers had trapped dirt and debris almost like Velcro, making a complete restoration unlikely, although the detailer set a realistic goal of getting the carpet to around 95% clean. The interior cleaning process began with vacuuming the carpets before moving on to the seats.AdvertisementAdvertisementThis was done to ensure no loose debris would transfer back onto the seats or get tracked around during the process. A cleaning solution was sprayed onto the stained carpet sections and agitated with a drill brush, which proved effective even against the vehicle's toughest, most mysterious stains.The detailer removed the front seats to make cleaning easier. He cleaned them thoroughly, including the sides and backs, using an all-purpose cleaner and steam. The stains on the rear seats disappeared almost like magic. A similar process was followed on the door panels and the dashboard, which were coated in sticky grime. They were treated with a diluted all-purpose cleaner and steam, which cut through the buildup almost instantly.Once everything was clean, the detailer spent several minutes applying an interior protectant to the plastic trim throughout the cabin, leaving a fresh matte finish. The windshield, which had a thick film coating the interior side, was finished with glass cleaner and a waffle-weave towel for a streak-free result.By the end, even the murky wastewater collected from the job served as a grim reminder of just how much grime had come out of the Blazer.The Owner's Reaction Said It AllImage Credit: The Detail Geek / YouTubeAdvertisementAdvertisementAfter roughly 12 hours of work, the Blazer was unrecognizable. When the owner returned to see her Chevy Blazer, her reaction was immediate disbelief."Oh, my god. Wow," she said, before the detailer jokingly reassured her, "Promise I didn't go and buy a new one."Her surprise only grew once she looked inside. "Oh, my god. It is. It's like brand [new]. Wow. That's crazy," she said, adding that the results looked "so good."She also opened up about why the SUV gets so dirty in the first place, explaining that a lot of gravel driving is "really hard" on the vehicle, making it dirty and dusty on a regular basis.
