it smells

my daughter and i cleaned the carpet in the lounge room the other day.  it came up so well i was extra pleased.  it was stained in places and i've been meaning to do it for ages so we hired a machine from bunnings and moved all the furniture.  a long and tiring day but with great results so it's ok.  however, i put the large mat over it to walk on and that was a huge mistake.  i came home from exercise yesterday and sniffed something bad by the front door.  i thought my grandson had left some food around but it turns out it got worse in the lounge room.  i went and bought some frebreeze and some vanish carpet deodoriser.  moved everything again and vacuumed it all up.  i was pooped by the end of it and fell asleep watching tv in bed last night.  it smells a bit today but not much and i'm hoping that with the doors and windows open it will get better.  the worst part is that my dear friend told me not to put the mat over a damp carpet because it will smell.  she was right and i was wrong.  oh dear
