why not use vinegar as your acid when pH too high?

[CarlD]

Gee, Evan.

I agreed with EVERYTHING but the last statement. Vinegar is a fairly strong acid--if you have granite or marble counters or floors you NEVER let vinegar land on it--it will eat the stone away!

My son has suffered from asthma and you sterilize the parts for the portable machine with white vinegar diluted with distilled water.

White vinegar is a very effective cleaner--I used it to soak the strainer for my Polaris 165 (the Dolphin's gone to the shop ) which was crusted with deposits. While it probably won't burn you on your skin the way muriatic will, the acetic acid in it quite diluted, whereas muriatic is usually 30%--plus hydrochloric acid ranks as the most acid on the pH scale, slightly more than sulfuric acid which is actually more corrosive.
