Dewinterizing the Hot Tub, Remove Glycol, Clean and Fill, Colloidal Silver, H2O2

Loveable Lou. Dewinterizing the Hot Tub, Remove Glycol, Clean and Fill. The vinegar solution I kept in the hot tub throughout the winter worked like a charm to stop the mold. Only a very light cleaning. The antifreeze had to be removed and the tub filled. Because I like using a chemical free hot tub I use Colloidal Silver and Hydrogen Peroxide (H2O2) to keep the water clear.
