When we think of car maintenance, screen wash might seem like a minor detail — just something to clean bugs or grime off the windscreen, right? But it’s actually a critical product for safe driving and vehicle health, all year round especially during winter months.
Using the wrong screen wash can do more than just affect visibility — it can actually damage your car’s washer system. According to motoring experts, the windscreen washer system can become clogged with algae and bacteria that form when water and leftover screen wash residue sit in the system. This often happens when drivers mix different brands or use poor-quality products. Over time, the resulting sludge can block the system and lead to failures that sometimes cost over £100 to fix.
To avoid this, experts recommend sticking with one high-quality screen wash. Therefore, product consistency is just as important as performance when it comes to protecting your vehicle.
