BOILER-NEUTRO
Neutralizer

DAVIES "BOILER-NEUTRO" is a special liquid blend of alkaline materials and is used immediately after acidizing a boiler.  "BOILER-NEUTRO" also will attack certain types of scale that acid has difficulty attacking, such as silica acale, which is most difficult to attack.  "BOILER-NEUTRO" has been found to be effective in knocking loose some last traces of scale that may be left in boiler and neutralize boiler at the same time.
How to Use
1. Drain all water treated with acid.
2. Remove all loose excess scale in boiler.
3. Fill boiler with fresh water.
4. Add enough "BOILER-NEUTRO" to bring the pH of boiler to 12 or 13. (Approximately 1 gallon "BOILER-NEUTRO" to 100 gallons water will generally bring the pH to 13.  Slightly more may be needed depending on conditions.)
5. Bring water temperature up to approximately 180 degrees and circulate for approximately one hour.
6. Drain boiler completely.
7. Remove all remaining loose excess scale in boiler.
8. Disconnect circulating pump, close up boiler, fill with fresh water.
9. Add enough "NO-SCALE" boiler compound to bring pH to 13 and boiler is ready for operation.
NOTE

The above procedure is for badly scaled boilers.  If boiler is not badly scaled, the amount of "BOILER-NEUTRO" needed will be much less and it will not be necessary to circulate for 1 hour.  For light scale, simply add enough "BOILER-NEUTRO" to bring pH of water to a pH of 9.  Circulate for 15 minutes.
