How to safely dispose of old fabric softener?
It looks lumpy rather than plain liquid.
Put it in the washer and let it soften your clothes... then run the rinse cycle twice. Try shaking it up before you put it in the washer. Its still good.
Add a little bit of water and shake it up and use it.
put it in the trash..if you choose not to use it..or..give it away..
You might have to burn it
Just trash it. I had the same issue with two bottles and when I tried to use it, it clogged my softener dispenser and I tried adding water and mixing and it didn't change a thing.
Read the label. If that doesn't work, check the household products database to see if that brand is listed.Otherwise, I think you'd have to call your local waste authorities, sorry.
