 The laundry detergents, that kind of stuff, it doesn't make sense. But if you have all these different specialty cleaners that are harsh ones, make sure that you're storing those in a building that's not attached to the house because that will show up. Even your garage, even though it's sealed up, it's still going to end up in that airspace because most of the time people put that air handler out in the garage and it is going to always be sucking just a little bit of air in.
