As Storm Austen batters parts of the UK with heavy rain and Storm Boelo is set to follow, a viral TikTok hack suggests sprinkling baking soda on a damp cloth and wiping it across the windscreen to improve visibility. The Met Office has issued several weather warnings across England, Wales, Scotland and Northern Ireland, with more expected over the weekend.
How the Baking Soda Trick Works
According to vehicle number plate firm Showplates World, the baking soda forms a thin coating that helps rainwater run off rather than spread. Motorists who tested the tip reportedly noticed a "big difference" in visibility and a reduced reliance on windscreen wipers.
An expert from Showplates World explained: "Many drivers don't realise how much dirt builds up on their windscreen over time. Even if it looks clean, a thin layer of grime can scatter light and make glare worse, especially when it rains. Using baking soda as a gentle cleaner helps remove that film and makes a big difference to visibility."
Caution Advised for Older Glass
The company noted that baking soda is mildly abrasive, which helps remove "grease, film, and other build-up" and makes the glass smoother, making it harder for water to adhere. However, applying too much or pressing too hard could scratch older or previously damaged glass.
Those trying the method should wipe the windscreen down with clean water or a microfibre cloth to remove any leftover residue.
Warning on Scratch Repair Claims
Another viral hack claimed baking soda could fix minor scratches on windscreens, but Robert Webster from MyCarGlass warned against it. He said windscreens are not made from regular glass and need "specialist treatment", adding that baking soda could "weaken the durability of the glass" and worsen scratches, potentially leading to costly repairs or a full windscreen replacement.
Webster continued: "Any mark on the windscreen can impact visibility, especially when headlights hit the scratch at different angles and can cause glare, making driving conditions dangerous. Using baking soda will not only worsen the scratch but can weaken the durability of the glass."
