Of course, I need a method that will not affect my lawn negatively. What is the best way to kill weeds?

What kills grass and weeds permanently? I have grass and weeds that just keep coming back between the pavers and it is a big job to constantly pull them out. There has to be a better way! Can someone tell me how to kill grass and weeds? What has worked well for you?
It doesn't kill the weeds, but it blocks them from growing: isometric sand. We have a brick patio and walkway. My husband uses a 5 in 1 tool to dig out the weeds and dirt. Then you pour on isometric sand and push it into the cracks with a broom. (Push it all in with none left on top of the bricks - trust me.) Then spray water. It creates a barrier similar to concrete between the cracks that doesn't allow weeds to grow.
Vinegar
You can pour any vinegar on the lines of your patio to kill the weeds and grass. You may need to do it more than once but it well work.
Go here. look for the herbicide you need.. I killed off about 100 lbs of weeds growing behind my garage that were growing through the fence into the neighbors yard.. it took about a week to work, but once the weeds are gone, you're good for about a year... I also use it to prevent weeds from growing in the stones on my driveway... Make sure to prevent overspray onto the lawn.. it'll kill that too... these are the chemicals that the professional landscapers use so make sure you wear gloves. They also have very effective pest control items! https://store.doyourownpestcontrol.com/lawn-and-garden-products/herbicides-weed-killers

Round-Up
Salt
I’d go with salt as it makes any area it’s applied to barren for a good while and it’s chemical-free. Just be careful not to get it anywhere you do want plants or grass.
Hopefully a plate compactor was used with the gravel and then the sand and then the pavers. Clean out the cracks, use either a mix of sand and Portland cement (toxic wear masks) or sandlock additive and premix (organic non toxic). Clean out the cracks of everything. If the pavers are no longer level, Lay down plywood and run the compactor over it, or use a handtamper. Fill in the voids carefully. You don’t want this adhering to the tops of pavers, stiff push broom at an angle to the pavers, wet down.
I’ve read the StayLock is able to flex, I’ve never used it. I have used sand and cement mixed in the wheelbarrow with a hoe. It’s lasted about 15 years before I had to start spraying the cracks that have occurred around the pavers and the 8 x 8 s I used to help keep all the components together.
Other than that, use glysophate to kill the existing weeds I use Hi Yield Kizz All which is 41% glysophate and cheaper than Round Up. You could also use some type of pre-emergent to kill future seeds from sprouting. The weeds keep coming up because the seeds from weeds keep germinating in the cracks.
Our neighbor uses a propane tank and torch and burns the weeds on his gravel drive., He has way too much fun with it, he’s started using it in his flower beds.
There are several here on HM:

This is not an exact science – approximate measures are totally fine 1 gallon white vinegar and cup Epsom salts and ¼ cup liquid dish soap Combine ingredients in spray bottle and treat weeds at the hottest time of day for best results.
