Hi, and welcome to JT Hughes Hyundai here at Shrewsbury. This is a Hyundai i20. And our customers are asking us how it's best to clean the wiper blades. So basically, you just lift the wiper on. Best solution is to use either some warm water or some screen wash on a tissue, and just give it a wipe up, turn it around and back down, and there we have it. Obviously, on to the next one do exactly the same. If this doesn't improve the vision or the wiping away the water on the screen, then it may be that you do need some replacement wipers, so please contact your dealership.
