Fabric softener is a scam

You can just use white vinegar instead of fabric softener. It's significantly cheaper, can be used for other non-laundry things, eliminates odors, and doesn't gum up your washing machine with residue.
- Further advice, don't use a lot of it. You'll see videos on youtube of people pouring like three cups of vinegar in their washing machine, don't do that. You only need a splash of it. If you use too much, the acid will eat away at the rubber gaskets and shit
  
  You definitely don't need that much vinigar. That said most new washing machine are using a chemical resistant silicone or TPE instead of more traditional rubber compound. This eliminated the already miniscule risk of acid damaging the seals.
  If you add 3 cups(about 700 mL) of standard 5% acetic acid bleach to 4 gallons of water(~ 15000 mL) you end up with a 0.2% acetic acid you will end up with a pH of something like 5.5 or about the pH of healthy skin. A lot of HE washers will use a 5 gallon initial wash so it's likely to be even gentler than what I came up with in my rough napkin math guesstamate.
  
  While I agree with the general sentiment, the vinegar won't be released and diluted until later in the load, so it sits in its full 5% acetic acid glory for quite a while.
  
  Most(maybe all) HE washers don't have mechanical flaps that hold back the liquids, they sit in plastic cups that empty by an overflow or auto syphon system when water comes out of a tube located above that tub or cup. It's a fancy plastic cup. Every plastic common to appliance manufacturing is resistant to 5% acetic acid. Chemical resistance of plastics chart
  I just looked at the fabric softener cup in my washer, it's HDPE(high density polyethylene). If you look at that chart you will see polyethylene is resistant to even concentrated acetic acid. The plastic bottle the vinigar comes in is made from a lower density polyethylene.
  By the time the vinigar leaves the cup is already being diluted by the fill water causing it to overflow or start the auto syphon. It will not damage your washer, but even if it did, you can buy replacements for the entire soap tray for relatively little online. The same can be said for most other appliance parts with the notable exceptions being large motors and some brands control boards. There are tons of write ups, tutorials and videos on how to fix broken appliances and replace parts.
  
  Yes, I was just being pedantic. Sorry to have triggered such an involved response, but thanks for all the information! From what I understand this is more of a problem in dishwashers, if you want to use it as rinse aid.
  
  No worries, I am a fan of pedantry. The amount of involved in the response was just me getting mentally stuck in a washing machine hole.
  
  O.O
  That's a terrifying amount. I use around 1/4 cup for most mid to large loads. 1/2 maaaybe if it's a large towel load. Does the job well enough.
  
  Meh. I say you need half a cup to a cup. A splash don't do it.
  
  Yeah if you can use just a splash you might have water soft enough to not require anything.
  1/2 cup to 1 cup is the sweet spot for my water, 1/4 cup on a very small load.
  
  I have a water softener and it works great for how the clothes feel from the wash. The half cup I add is mainly for odor eliminating.
- Is there anything vinegar can’t do?!? Between white and apple cider vinegar, I feel like they cover so many areas of cleaning and household stuff.
  
  Vinegar ain't basic, that's for sure.
  
  Ha ha... groan
  
  I have been thinking of making my own fruit vinegar this year. Hopefully good enough to consume rather than just use for cleaning
- Please don't do this. It seems like a hack, but will mess up your machine bc of how corrosive the vinegar is. Learned this the hard way.
  If your clothes really need it, just soak them in a bath of diluted vinegar for a while, then rinse and wash.
