I am using a liquid detergent and I use exactly the half of the detergent they say I should use. If a the washing machine requires 1 cup, I do half. Mostly because I don’t trust the company to put me over their interests.
Now, what will happen? Will my clothes end up staying dirty? Will it not remove stains which a full cup would have removed? Will surfexcel kidnap me and torture me for not obeying their commands? Help meeee!!
Too little and your clothes will be exposed to more friction, causing things to get pulled and rubbed more.
My newer LG with a mobile app once scolded me for using too much.
Wait, how does the detergent affect friction?
That just sounds wrong
Mix some in water and feel it.
They work by getting between the fabric and the “grime” and lifting it off. Also something to do with surface tension.
That’s a bit thin, is a lot like 'it’s totally true, bro, just try it. Anecdotal arguments.
I need some fluid dynamics here
You need someone to prove that soap is slick?
I mean that is not the main function. In a tumble drier cloathes rub against each other without any soap too, without disastrous tearing of fabrics.
Tumble drying does drastically reduce the lifespan on the clothing though…
Well fuck LG, just build a tank into the washer that I can fill with a gallon of detergent at a time and do your own metering.
