It’s a moment every driver dreads: you’re driving in St Louis and one of your BMW warning lights comes on. If it’s the battery light and the engine’s still running, this is probably good news, as it means the problem is likely a loose battery cable or car battery corrosion. Before you schedule a battery charging system test with our service center, you can remove the corrosion from the car battery yourself. Let BMW of West St Louis show you how.
Time is what causes car battery corrosion. Over months of driving from Ballwin to Ladue, your BMW’s battery is repeatedly heating and cooling, causing it to release hydrogen gases. Over time they mix with the surrounding material and create corrosion where the battery terminals connect to the cables. Along with activating your battery warning light, car battery corrosion can cause your car to have weaker power, and you might have trouble starting the engine.
When you want to know how to clean car battery corrosion, watch out for old misinformation. Specifically, don’t pour soda onto the corrosion. While it might remove car battery corrosion, soda will leave behind lots of other ingredients that won’t help your battery. Besides, baking soda and water work better, and they cost less. You can also purchase battery cleaner to do the job.
When it’s time for a battery check, schedule an appointment with the service center at BMW of West St Louis. You can also contact us if you have any questions. We want to help keep your vehicle running smoothly for many years to come.
