My landlord mentioned in passing that the carpets in my apartment were "due for a professional clean" and I took that as a hint I'd be losing deposit money if I didn't do something about it.
Looked up carpet cleaning services and they wanted anywhere from $180 to $280 for my size place. Then I noticed you can rent a carpet cleaning machine from most hardware stores for like $35 for 4 hours.
The amount of filth that came out of carpets I thought were clean was actually disturbing. Like I vacuum regularly, I take my shoes off at the door, and the water still came out the color of a swamp. Did it twice in the same day just because I couldn't accept the first result.
Saved like $200 doing it myself and that alone made my week. Then I did my couch. Then the bathroom rug. I'm basically a different person now. #finance source
