For a long time I tried to figure out what was causing our house to have a bad odor, more chemical than anything else. Our son was visiting and suggested it could be the Glade Linen spray we were using in the bathrooms. I noticed the odor when I opened the door after being gone part of the day.
Decided to toss out the Glade and started spraying 50/50 vinegar/water in the bathrooms when needed. The vinegar smell does not linger very long.
Much to my surprise the house no longer has the unpleasant chemical odor.
I now use vinegar/water spray all over the house being careful to not spray on furniture. The whole house smells better.
