Anyone know how to delete achievements?

[Noise]

I recently found out my brother went to one of those achievement servers and did some cheat do get most of the achievements on tf2,
Anyone know how to reset them? :?

I'm pretty sure there's like a steam achievement manager that you can DL to delete them. But I'm not completely sure if it's safe or not. I heard about it on the TF2 official forums once.

I would use caution.

If thats the case, I won't do it. Thanks for the info.

I've read there is a console command "achievement_reset_all"

I have not used it and do not know if it works. You could try it out.

Doesn't work, there is achievement debug but thats it. :|
