I was at the Uptown Mall yesterday, when I noticed a young man with a weed sprayer. He was going to all of the cracks between pavers and spraying the weeds. This was an area right beside a playground and the Starbucks, where many children play and many dogs are walked. I had my daughters little dog on a leash.

I immediately headed over to investigate what I thought was a bad situation. Then I smelled vinegar. I talked to the guy running the sprayer and he showed me the supplies he uses. He mixes vinegar with salt. The solution is added to the plants on hot days when no rain is expected. They dry out and die. Apparently this works quite well, since there were very few little weeds coming up.

 The guy told me that he has had success finding work around other play areas , and that it has proven to be a viable part time business.

I'm going to try this on some of my customers paved areas , to see how well it works.

Do any of you have other concoctions that would work in this situation? I would not be looking to spray anything in areas where food is grown or on lawn areas. This would be limited to the difficult weeds that often pop up between paving stones and the weeds that grow in the crack between asphalt paving and concrete foundation walls. I have a commercial client who might choose this option.

Look for 'Agricultural Grade' vinegar. Way, way cheaper than food grade.
I have used vinegar in the cracks between sidewalk/structure. Worked great (for a while).
If you can reapply it just as the new growth appears, you can easily keep ahead of the problem.

Just about everyone who moves out of a house that I'm working on, leaves me a bottle of vinegar. Supply certainly won't be a problem.

I am often left everything contained under the kitchen and bathroom sinks. There must be something else there that is relatively safe, that would also do harm to the unwanted plants. Lack of a visible residue is important for many of my situations. It would also be nice to have things that won't clog the spray nozzle.

I wonder about household bleach. I know that there are many commercial bleaching compounds which would be very bad but something based on ammonia or hydrogen peroxide might be acceptable.
