Why a Small Change in Thickness Alters the Dose
Viscosity is a liquid’s resistance to flowing. A thicker dish soap resists motion as it passes through the bottle’s narrow opening; a thinner one offers less resistance. With the same bottle and a similar squeeze, the thinner soap can travel out more quickly, so the same brief pour delivers a larger amount.
That makes the bottle’s opening and the person’s timing part of the dose. People often stop squeezing by feel—when they think they have dispensed enough—rather than measuring each pour. If the soap flows faster than expected, that familiar squeeze can overshoot before the user adjusts.
The Cost of an Unnoticed Overshoot
The extra dose can become a quiet household expense: the bottle empties sooner even though the number of dishes has not changed. More soap may also mean more rinsing to remove the suds. The practical fix is to watch the stream rather than rely only on the usual squeeze, especially after switching to a runnier formula.
A faster pour changes how much reaches the sponge, not how much cleaning the dishes necessarily need.
