Rock salt as a weed killer for gravel driveway

[DIYAd]

My gravel driveway is looking a little too green and i want rid of the weeds and grass.

Its approx. 200 square meters.

I've read about Salt being an affective weed/grass killer but what about rock salt ? Surely its the same but just about 10 times cheaper (ice/snow clearance etc etc)

Use Pathclear.

Rock salt would do the job. But you would have to use a lot over a prolonged period and it will leach to god knows where killing as it goes. Therefore it's a dumb idea. Listen to John.

It will seep into the surrunding soil, making it hostile to any plant apart from Marram grass and other coastal plants.
