We also didn't have a carpet shampooer. When we lived in Big Town America, my Nana insisted on coming over every month or so to do it herself.
So when my Mother-In-Law bought me a new Bissel upright for Christmas, I jumped right in.
And damn, my carpet is filthy.
Today, I shampooed a spot roughly 4.5 by 4.5 feey square.
I sprinkled some baking soda on the carpet after vacuuming instead of before and then shampooed over that. The jury is still out on whether or not it actually did anything.
I think the pictures speak for themselves, though.
The first picture below is after shampooing the carpet one time through with a heavy traffic cycle, letting it sit ten minutes, and then one rinse cycle with my machine.
The second picture is after shampooing with a normal cycle and then rinse cycle, without letting it sit for any length of time. That was the point for water started coming up clear.
Gross.
However , while running my obnoxiously loud machine I had plenty of time to think. And I decided that instead of being named after a color, carpet ought to be named after what will stain it. For example, my carpet would be called potty-training-apple-juice-and-orange-slushy.
Also gross.
The other picture that is not of dirty carpet water is off my silly ghost children playing in the sheet that was meant to cover the carpet while it dried.
At least something cute came out of my filthy carpet. <3
