Looking for long term cheap solution to killing lawn and weeds, something that can be sprayed. Can't use diesel as it'll jam the sprayer, already tried chlorine and bleach.
Is there a concentrate out there I can dilute to spray? Don't mind if it will affect the soil so grass will never grow again.
something like one of these;

I've used both the mitre10 / Bunnings ones. It kills weeds good (be patient it takes time) and grass (accidentally).
