So I'm taking out my leaking csf radiator and find stop leak under the cap. Fu!!!!!!!!!!!!@@@@k I'm steaming. I paid to have a shop fix my heatercore in the dead of winter last year because it fogged up so bad I couldn't see. This is exactly why I don't take my jeep to shops, Flippin thieves!

First off, take it back to the shop and show them.
Second, the best way is to replace basically every component in your cooling system. You can try just flushing the system multiple times, but I've tried this before and it was nearly impossible to get every bit of it out of the system.

show them, for what? Im not trusting them to fix this if this is how they fix a heater core!
can stop leak damage a radiator?( its copper brass), do I need to worry about the valve body getting damaged by this? I cant believe these bastards poured stop leak into my jeep!
I believe you saying its not easy to get out because it sat 1/4 like mud under the fill cap.

I would make a huge scene if you can prove that they didn't actually replace the heater core and they said they did. Like huge scene - throwing **** in their lobby and stuff.
THEN,
I would install a cooling system filter. "NickInTime" on Youtube has a video of how he ran his on his XJ

Additionally, I would probably do an Amway SA-8 Detergent flush (google it, its no-suds laundry detergent that is great at cleaning oils), and flush with water several times.
Here's a great write up on it:

and it better be replaced for a 700$ job, ill see if i can find the reciept. I have no way to prove they put stop leak in other than Im the only one that works on my jeep and its never had the cooling system worked on by anyone other than the geniuses that poured pancake batter into my jeep. I replaced the rad, pump,& stat the winter before it went in to get the heater core serviced, and i certainly know better than to throw cheap crap like stop leak into a vehicle.
