Intercooler calcium/mineral block

While I don't drive a Termi, my KB intercooler circuit is basically SVT parts. After many cheap ice downs at the strip I've got some serious flow issues. What are you guys doing to clean the system? I ran a white vinegar only through it for a day before having my local Rad shop reverse blast the system with his high PSI/water air gun and got some of the chloresterol out but not enough. Can I safely step up to Say, CLR? LMK what you guys have done without removing the intercooler/heat exchanger to get my flow back.
Thanks for reading!

Subbed for info. Ughh I was looking forward to using ice at the track too. Cobro life can never be easy.

Thanks for the reply/ bump, we can't be the only one's with this issue.

While i don't have this problem I was planning to use ice at the track and wonder if anyone else has heard of this. I was also planning on running water and water wetter for some of the summer months.

CLR has always been a perfect solution to calcium build up. It dissolves it without harming ANY metal I have even gotten it on. I've even used it in engine blocks. I get it in gallon jugs at Walmart. And don't forget that you can keep it and reuse it if it isn't too dirty.

What about the rubber hoses and the pump, safe for those as well?

I've used CLR to unblock a few heater cores, copper and aluminum both. Worked really well with no issues. Don't see why an intercooler would be any different. Should work.
