Using this Verus windshield washer fluid reservoir cap is easy. Just snap it onto your windshield washer fluid reservoir, just like you would with a factory part. It's designed to fit securely, so you don't have to worry about it coming loose. When it comes to maintenance, it's quite simple. You can clean it with a mild soap and water solution every once in a while to keep it looking great. Just make sure to dry it thoroughly after cleaning. As for the color, whether you choose red, blue, or black, they're all durable anodized colors that should last a long time. One thing to note is that while it's made of high - quality 6061 - T6 aluminum, avoid using any abrasive cleaners that could scratch the surface or damage the laser - engraved logo.
