Bubbles in the wash….

So my gf and I are having a debate. I’d like to know if Reddit can offer us some kind of resolution on this issue.

Ever since I was a kid, I’ve been told that anything you wash, there needs to be some bubbles, or soap suds present in order for the soap to be effective in cleaning. Dish soap-suds, hand soap-suds, car wash-suds, body soap/shampoo-suds. Hell even tear free soap to wash infants in suds up when you are washing. But I noticed that the laundry detergent is not producing any suds at all. I’ve used what is recommended to wash a single load on a single load…..no suds. I’ve used what’s recommended for 6 loads of laundry…….no suds. So why is it that every other kind of soap we are using is expected to produce suds in order to prove that it is doing its job, but not our laundry detergents. It doesn’t even seem as though the laundry detergents scent is still present out of the wash. They just smell like wet clothes until you run them through the dryer with a dryer sheet.

So my question is, are suds, or are suds not, the indicator that you used enough soap to clean your clothes in?
