    Is there something special with destiled water and if yes could you tell my why and can I use a hair dryer for faster because you said something about air being blown so can I use a hair dryer for that

      @@lucasmorawetz4934 Good questions.
      1) Regular water has many minerals which will make patches of dirt if you rinse the mirror with it. It is ok to wash it with regular water but the final rinse must be with distilled water which has zero minerals.
      2) Hair dryer is OK ONLY if it blows cold air. Hot air can damage the coatings. My dryer was blowing cold.
