Over the time I've been on 'The Fun' {mainly in reading mode} I've seen several, "How do I get rid of black streak"? threads. You might like to try 'Sugar Soap'. I tried a test patch a month ago and it not only works but it has had no detrimental effects (that I can see). Moreover, it's cheap and really works well. I use it undiluted on a microfibre cloth and it dissolves even the stubbornest black streaks with very little if any EG (elbow grease) required. I then wash it off with 'non-drought' water. Obviously try a test patch first but I hope it solves a niggling problem for some. Cheers PS. I used a bottle bought from B and Q. Couple of quid I seem to remember and should last ages.
