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!!
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?
