Aluminum Boilers, Condensing Heat Exchangers, and pH-Sensitive Systems | Removes Manufacturing Oils and Post-Descaling Residues | Neutral pH Cleaning That Won’t Damage Aluminum Where Alkaline Detergents Will

CI Neutral Boiler Cleaner is BD86’s counterpart for aluminum systems — the pre-startup and post-descaling cleaner for boilers and heat exchangers where conventional alkaline detergents would attack the aluminum surfaces they’re supposed to be cleaning. Working pH of 7.5 to 8.0 keeps the chemistry within the narrow band that aluminum tolerates, while chelating agents and non-foaming surfactants emulsify and remove the manufacturing oils, installation grease, and organic residues that cause foaming, surging, and poor heat transfer if left inside the system at startup. Also functions as a neutralizing rinse after acidic descaling — bringing system pH back into the safe range for aluminum before corrosion inhibitor treatment begins. The same metallurgy logic that drives the split between CI Alum and the conventional boiler compounds applies here: aluminum needs its own cleaning chemistry, not just its own treatment chemistry. Use Neutral Boiler Cleaner to prepare the system, follow with CI Alum or CI No. 25 for ongoing corrosion protection, and the aluminum program is complete from first fill to continuous operation. If the system is conventional steel, use BD86 instead — it’s the alkaline cleaner built for metallurgy that can handle higher pH. Two cleaners, two metallurgies, and the wrong one in the wrong system creates the problem it was supposed to prevent.
