One of my guys didnt divert the downspouts very well when cleaning a roof today and the runoff went down the driveway and customer is complaining about it. They rinsed and rinsed and there is still a shadow. House is for sale and I need to see if there is cleaner that might help lighten it up more without damaging sealcoat?
 
Probably re seal coat it for $99. Around here anyways.

Thanks for the help. I will try the soap and scrub method first. Unfortunately to sealcoat a driveway this size around here would run about $400 so that is the last thing I want to do. I know it would lighten up sooner or later after a couple rains but she needs to have pics done for listing the house so dont have time on my side.
 
Don't do it yourself - there are different formulations for sealcoat, and if you use the wrong one it will stick out worse than a sore thumb. A lot of guys use straight up coal tar watered down, but a lot of guys put a crap ton of sand and latex in their mix...... use the opposite and you WILL be redoing the entire driveway. If the driveway is really shiny and the seal coat looks a bit "thick" it's probably a latex mix. If it's closer to a matte flat black color and looks kind of "thin" your on a coal tar. Either way, you're going to be able to see where it was fixed..... but a pro will be able to cover your tracks to an acceptable level.

Just ended up knocking $200 off her bill. Thats not worth my time to try and fix myself. Nor did I want to try. We tried blending it in and even reapplying some of the mix that originally streaked it.. It lightened up but not to her satisfaction.. Thanks for all the help
