I Killed My Dual Field

Fresh (tap) water and bottled drinking water are better than nothing, but distilled water is 100% better than either!

The use of an electronic spray like the CRC Electronics Cleaner is better than Isopropyl alcohol (91%).

Rubbing alcohol should NOT be used as it contains ethanol and sometimes other additives for color and aroma.

WD-40 should never be used on electronic circuitry, especially rotating controls.

Always use the correct product for the results you are trying to obtain.

hope you can save it good luck

De ionized water used in AC repair work.

Nice save Scoundrel! Hope it gives you many more years.
