How to get rid of fireflies

Hey all!

I've been trying to render scenes out, but keep running into pesky fireflies (reference: https://imgur.com/d5fGs0H)

I've tried upping the GI clamp and fussing with the Hotpixel Removal setting, but I always have multiple pixels just hanging out.

Anyone know what other settings can have an impact on this?

Hi maviseverett,
what about the red material?
Do you have high power values for bump and or normal map nodes?

I don't have anything on Bump or normals. Should I?

I think Bepe refers to possible artifacts (like a bump) catching light.

Yes correct, sorry, sometimes my english is not so good.
A Power value of 1 for Bump map can be way too high, depending on the texture used, and the light gets trapped producing artifacts.
