Pre-clean greasy parts with SF-77 degreaser and a pressure washer or steam cleaner, then rinse. The K-1547 Acid Test Kit verifies strength — a correct 1:5 dilution reads seven drops. Dip parts 3–5 minutes depending on corrosion and temperature (it works twice as fast at 90°F as at 50°F). Rinse immediately to prevent a white film from re-depositing. May be heated up to 120°F to speed cleaning, but no higher, to avoid driving off hydrogen-fluoride fumes.\u003c\/p\u003e\n\u003ch3\u003eCautions \u0026amp; metal removal\u003c\/h3\u003e\n\u003cp\u003eBecause it’s an acid, A.R.C. removes a small amount of metal by etching, so it shouldn’t be used on very close-tolerance machined parts. A five-minute dip removes about 0.67% of a typical 15-mil radiator-tube wall; longer dips remove more. It will etch glass, remove anodizing, and attack various metals differently — test first. Plastic, rubber, and most paints are unaffected. Keep grease and oil out of the tank, as they rapidly deplete the solution.

You can reduce it four ways: store parts dry, rinse\/neutralize chemical residues, keep parts away from flux and acid fumes, and use a corrosion inhibitor like Green-Stop. A good inhibitor may reduce or even eliminate the need for the first three measures depending on conditions — and will always improve the situation.\u003c\/p\u003e\n\u003cp\u003eRepair shops can dip rebuilt radiators, complete heaters, repaired cores, heater blocks, cleaned and tinned tanks, and brass oil coolers held for future use. To prevent pitting inside brass tubes, the solution must completely wet the insides. Manufacturers using a non-corrosive, low-residue flux have less corrosion to begin with, but in humid climates Green-Stop is a great help. It’s supplied as a highly concentrated liquid for economy, based on a proven inhibitor system used successfully for many years.\u003c\/p\u003e\n\u003ch3\u003eDirections\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMix 2 ounces per gallon of water — enough to fully immerse the parts.\u003c\/li\u003e\n\u003cli\u003eBefore immersing, rinse parts free of flux, acid, and caustic residue (a neutralizer\/cleaner may be needed in severe cases).\u003c\/li\u003e\n\u003cli\u003eImmerse to wet the entire surface inside and out, with no trapped air pockets.\u003c\/li\u003e\n\u003cli\u003eRemove, drain, and air-dry away from flux and acid fumes.\u003c\/li\u003e\n\u003cli\u003eReplace the solution when it looks cloudy or dirty — typically about 100 parts per batch.
