This is not a me-too product.
We refused to make just another radiator flush. If we couldn’t develop one worthy of the Rislone Hy-per Cool name, we wouldn’t put it in our product lineup. Simple as that.
After several significant refinements to our product formulation, what emerged from our lab was Rislone Hy-per Cool Cleaner & Super Flush, the highest-performing radiator cleaning product you can buy.
Your cooling system is insanely important, yet overlooked. Give it the attention it deserves.
