How to keep the air quality inside my home healthy

My doctor, Mary Jane Mack, taught me the following to keep the air quality inside my home healthy.  I am not referring to vacuuming or dusting.  However clean your home is, bacteria lives inside the drains, and bacteria is air-borne.  Especially with the climate in the Northwest, we often keep our windows closed much of the time, so we are even more affected by indoor air quality.

The product I use is “Instant Power mainline Drain Cleaner”.  There is no odor.

128 oz. Main Line Cleaner

You can buy it at Home Depot in the plumbing aisle.  It’s also available in some retail stores.  You can do a search online.  The link to Home Depot is


For each drain in your home, slowly pour 1/2 gallon (that’s half the bottle) down the drain. (except the toilet.  I’ll talk about that later.)

For the drain used most –probably the bathtub / shower drain (with hair and hair product going through it) I would use the entire gallon the first time you ever do the drains.


(It is a good idea to wear gloves and glasses when you are doing this, just in case.  If any gets on the skin, rinse with water first and then white vinegar.)


Let the drain cleaner sit for 7 hours (maybe it’s more convenient if you do this before you go to sleep)


Then before you use the drain again the next morning, boil some hot water and pour it down each drain, then run hot water down each drain for about 5 minutes.

You are done!


For the toilet, you can use either

Chlorox (lemon-scented smells better) about 2 cups


Bio-kleen Bac Out Drain Care Gel (the first time you do this, use 1/2 bottle)

(Bio-kleen smells good and is environmentally friendly)

Leave it in the toilet for several hours (or overnight) then brush and flush.
You are done!
I maintain the air quality inside my home by repeating this every month.  But the quantity I use for maintenance is:
Mainline drain cleaner (3 cups for each drain)
For toilet, 4 ounces Bio-kleen or 2 cups chlorox (lemon-scented smells nicer)
This will help a great deal with maintaining good air quality inside the home (or anywhere with a drain indoor!)
Again, this has nothing to do how well you clean your home or how often you have your windows open.  Bacteria lives inside drains, however clean your space is.  These products are a great help.
