Anyone have any tips?
1 gallon white vinegar
1 cup salt
1 tablespoon dishwashing liquid
Mix well. Spray on a sunny day.
Or, just pour some boiling water (with or without salt) on paths to kill weeds between cobblestones, etc.
Some people dont like putting salt in their garden, but its a fun way to get rid of slugs/snails.
we lay newspaper and mulch our paths with hay/straw, you can use wood shavings or sawdust, or small stones. the sawdust will help stop the slug's n snails from crawling from bed to bed.

Short of digging out the taproot, a teapot full of boiling water is my usual way.
Boiling water works pretty well for this but established perennial weeds will often return quickly. Using dishwashing liquid in the garden is not an organic practice; it's synthetically produced and is not on the OMRI list.
Vinegar, boiling water, salt, etc. will all kill this growth, for a time and will also allow some organic matter (those dead plants) to accumulate which when combined with the dust from the air will form a good soil for other plants to grow in.
The best way to clean weeds growing between pavers is to lift the pavers up and clean out the plants and any accululated soil that is there, a bit more physical labor but a longer term solution to the problem, unless the pavers are cemented in place.
For weeds growing in expansion joints in concrete walkways/driveways, between patio stones or bricks, or in gravel/lava rock mulch, I just fry them with my propane torch. Works great -- in fact, I have company coming this weekend, so I just tonight fried hundreds of little tiny germinating weeds in the expansion joints in my concrete driveway and front walkway -- fast, easy, non-toxic (unless you consider the C02 greenhouse-gas pollution it generates), and the weeds literally burn up and are gone. A few do try to come back from the roots, things like dandelions, but I cook those an extra long time to make sure.
