Mandark Car Sunroof Drain Long Pipe Cleaning Tool, 72 Inch Flexible Vehicle Tube Drain Straw Cleaner, Nylon Stainless Steel Double Ended Auto Cleaner Hose Brush, Universal for Most Cars (Blue)

I used this for my vehicles with sunroofs. This is great for quick drain tube cleaning if you don't feel like using an air compressor to clean the tubes. The vehicle I tried it on was a 1974 VW beetle that I am restoring that has a metal sunroof. The drain tubes had years of crud in them and I was able to easily thread the 72" cleaner through the 4 drain tubes on that car. (I still used an air compressor afterwards, but that was because there was 50 years of nastiness in there) If this thing could clean that crusty old bug, it can clean anything's drain tubes. After cleaning, it wasn't damaged at all and will be able to be used again in the future. I highly recommend this.
