Black streaking on asphalt driveway like roof, roof mix and surface cleaner?

Can I use a 5% roof mix on an asphault driveway that have black streaks running down it like a roof does? Will that be enough? I’ve surface cleaned a few driveways before but I need to get larger orifice meg nozzles because it’s alittle to rough. I have a 4200psi 4 gpm and a 20 inch cleaner running stock 25 degree 2.5s should i get 3.0? 3.5? or higher

No Unless you rinse it right away it will leave marks where the bleach was. I had to almost repave a commercial lot one time because I’d been doing their stucco building and I flushed out my system in the parking lot and didn’t rinse it nearly enough.

Usually on asphalt you just apply a sealer top coat. Provides an almost like new appearance.

so just use straight water to be safe?

On asphalt, dragon juice and water is a safe cleaning method or just water alone

there is also moss and other crap on the driveway

Do you have any pictures ??

You can use some SH, like a real strong HW and even go to about 2%, just don’t let it dry. Get it washed and rinsed really well.

today I can get them

I’ve had too many bad experiences with asphalt, so we don’t wash them at all.

Why would you use sh. Is the streaks on the asphalt organic?

i didn’t wash it yet . it just looks like the dark stains you see on the roof .

That sucks for that guy. Good lesson learned

In another video he said it cost him 400 bucks to have it resurfaced. Ouch.
