Price of radiator flush was Rs. 59/-
the procedure is written on the bottle, my bro have done the radiator flush from mechanic so i do't know how.
my radiator is serviced and washed with that radiator flush, the coolant level is stable, don't know whether it is the radiator flush or service which is keeping the level maintained. but for sure the flush will keep the interior of the radiator and engine pathways clean from rust and other impurities as it contains sulfuric acid.
