Killing grass in driveway

I want kill the grass and weeds in my gravel driveway. The last time I used some stuff I got at the local co-op and it did a great job of killing the vegetation but also ran off into the yard and killed some area's of grass in the yard. I'm trying to get something that has good kill that you don't have to reapply like you would have to with roundup but yet something that won't run off the drive. Any ideas?

 Old gasoline you drain can be spritzed on weeds, pretty effective so I have been told.

We sell Pramitol, hyvar xl and others for driveway control but I warn anyone with a sloped driveway or ditches near that all of them will wash into unwanted areas.  It's just the nature of long lasting chemicals especially on hard surfaces that don't soak up run off.  I once brought a spraytruck home rather than return it to work late at night and left it in the drive way.  I drove it to work the next morning after a hard rain.  Wife didn't like the lawn control i created.  I planted sudan grass in the area as i knew it would grow and mowed it all summer.  By that fall all the chemical had been taken up and i planted lawn grass again.  Would not have worked with Pramitol.

Back blade used occasionally.

salt it

here's what you do. i have a 4000 sq.ft gravel parking lot at the front of our farm. i use a 3 gallon back pack sprayer, go to rko and buy the 2 1/2 gallon of weedkiller (it's generic roundup) $34.99 or $29.99 on sale. then go bye some liquid pre-emergent. it's not very expensive either. the round up kills the existing weeds and the pre-emergent disrupts the germination process. if done properly you won't see one weed for 8-12 weeks per application. when u see a few weeds starting to pop out repeat. i do my parking lot in spring middle of the summer and in the fall, and no weeds. not to bad for being at the front of one of our fields. just don't spray right before it rains and u won't have any runoff problems. try is guaranteed to work. pete

are you just spraying calcium chloride to salt your driveway?

one winter...a salt/sand truck broke something along side the highway....they had to run a bunch of their load out to fix it. leaving a quite large pile along side the roadway. it stayed there for over a month...so i went out and scooped it up and poured it in my driveway. my driveway stayed clear all winter long as the salt kept the snow/ice melted all winter, and nothing grew in the driveway all year, and for several years afterwards. just plain old cheap rock salt. nothing still don't grow where that pile was along side the road.
