Product cleanliness opinion

I'm a lil over a year into my job and a constant argument I've seen. How in depth should you clean the project before sending it to paint? OUR workplace has a wash bay and spot for grinding touch ups and double checks before going to powder coat. No one seems to agree on how much clean up the welder should do before sending it off. Some say scrape the splatter and go, others degrease it too, and some buff the steel specs off. I've had a couple say all of thats paint prep just weld it and move on. What do you guys think?
