The self-described "regular dad" then showed his viewers how they could use a cheap kitchen essential to tackle the pesky problem. Bo, while sitting in the driver's seat of a parked car, demonstrated wrapping a paper towel over the back of his hand. He then raised it to the inside of the car's front windscreen and wiped it from bottom to top with the back of his hand. Bo said: "Put a paper towel on the back of your hand and wipe your window down this way." More than 1,000 comments were left beneath Bo's video, as many thanked "dad" for his help. One person said: "This is the nudge I needed to finally clean my car. Thanks, dad." Drivers planning to use Bo's tip can purchase a large roll of multi-purpose kitchen towel for just £1.35 at Asda. The resourceful dad, who goes by @DadAdviceFromBo on TikTok, said drivers should also be sure to wipe down their dashboards at least once a month, perhaps with car interior cleaning wipes. For many drivers, it doesn't take long for dust and grime to build up on the interior and exterior of their vehicles.
