Trying to set MeshRenderer to false

The code below still draws the object when run, I’m missing something obvious I think!

particleArray[a] = Instantiate(explosionEventScript.explodePart01, 
                          Vector3(a * 2,0,0),  Quaternion.identity);
particleArray[a].Find("Explode-part-1").
                          GetComponent(MeshRenderer).enabled = false;
particleArray[a].active = false;

try

particleArray[a].Find(“Explode-part-1”).renderer.enabled = false;
