Whilst claying, glazing and waxing my Zed yesterday I noticed small particles of fallout adhered to all the exterior glass. I normally use wire wool to remove glass contamination but thought I would give this a try. I got myself a small piece of 3M Fine Clay, lathered up the glass with Wurth Active Glass Foam and worked round in an up/down & side to side pattern. The result is quite amazing...the cleanest, smoothest, shiniest glass ever ! Give it a go !
