At 45 I live in a "shortened" house. I always want it to be clean and meaty when my daughters, sons-in-law and grandchildren come to visit! Due to all the rain we had last year (and AGAIN this year) I noticed a bit of a musty smell. It was recommended to me by a friend and now the muff is gone! And all my other products make my house smell amazing! I sincerely recommend everyone, especially those living in old houses, to try this product! That is amazing!
