Zebra Gutters

[smittie1984]

I always get people asking this. Talking about those little black stripes and how to remove them.

Is there anything that can remove those stripes? or is it just tough break? Also what are those stripes from?

I have heard a couple of things. Someone mentioned using Purple Power but washing it off immediately. But I'm afraid that could cause more damage in the end by removing any coating that could be there.

I did a search also and couldn't find any answers.

A butyl based degreaser like PP is the only stuff that will effectively remove the black streaks. If you're doing houses on a steady basis, it may be best to buy professional strength chemicals from a distributor. You will save money in the long run.
