I’ve noticed when cleaning dishes that when the cleaning solution is “sudsy,” cleaning seems to happen more quickly (less scrubbing, etc.).
Is this because:
* The suds themselves help with cleaning
* The suds don’t help with cleaning but they indicate that the cleaning solution has a particular desirable property;
* The suds don’t help with cleaning and aren’t related to any desirable property.
A related question is: For any effective cleaning solution can one create a cleaning solution which is just as effective but has very little sudsiness?
