I have some particle emitters in my scene, but when the player dies the scene reloads. When it does, the particle limit is hit since I think the old particles aren’t being cleared out for the new ones to spawn. Is there some way to instantly remove all particles?
If you make your scene a collection proxy, it should remove everything on reload.
I’m doing that already… Not sure what needs to be done to fix it. The particles I have have a fairly long lifetime. I’ll probably have to mess around and see if there’s some workaround. Not sure 
I’ve submitted an issue about this on github: https://github.com/defold/defold/issues/5265
It hasn’t been reviewed by the team yet, but on the assumption it’s possible to do then giving it a 
reaction would put it higher on the list of priorities.

Discussing it now! It’s an often requested feature.

In all similar situations my solution to this is to set the particle color to full transparent black.

I remember reading that moving the particles outside the render scope (say, z -100) also works.

I can confirm this works! Really handy when you don’t want to unload the collection proxy.
particlefx.set_constant("#particlefx", "splat", "tint", vmath.vector4())
Fyi: I wasn’t able to get this to work. I tried setting both the game object and the particle component with no luck.
