What’s the most effective way to kill grass growing between the pavers? Non-toxic would be preferable.

A propane torch.
Yeah, quick couple passes and they’re done. Then you don’t need to worry about friendly fire around the edges.
Though make sure not to hold it over a spot too long…

Where can I get one of those?

Just don’t burn the pavers like that one dude.

This is the way.
Power wash the joints clean of dirt and old sand. New polymeric sand swept into joints. Water in to set. Done.
I highly recommend cleaning all of the dirt out between the pavers and then using polymeric sand for pavers to fill up the gaps.
I fought grass and weeds in between my pavers for years. And then I just cleaned in between them with a pressure washer and used the polymeric sand. The sand hardens and stops dirt from getting between the pavers again so there is nowhere for grass/weeds to grow.
It was a nice weekend project but should hold up for years before I need to apply the sand again. I wish I would have done this a lot sooner.

Second this and highly recommend it to save your patio from shifting around too!
Glyphosate or a weed burner. Then use pre-emergent to control.

When you say pre-emergent, what type do you mean? Won’t the weeds come back since there’s opening all over the place? I’ve been curious about this as well because I have the same problem.
@Dana
Glyphosate is a post-emergent herbicide; it kills weeds after they’ve established. Pre-emergent herbicides kill weeds before they establish.
You clean up with post-emergent and maintain with pre-emergent.
@Ridley
This.
Also, fun fact:
Glyphosate is formulated to be rendered inert when it has the opportunity to bond with the clay particles found in soil. That’s why you can treat with glyphosate and plant grass in the same day. I know no one asked, but I found that fact neat 
@Oak
True, thanks for adding that fact!
@Ridley
Another fun fact. Pre-emergent works by creating a chemical barrier preventing all seeds from germinating in the soil where it’s been treated.

This is false. The seeds do germinate but they end up dying as they’re not able to penetrate the vapor barrier created by the pre-emergent.

Why was I downvoted for asking a question? I really hate it when you ask a question to be downvoted. We ask questions because we want to learn and gain knowledge.
