Why Using Cat Litter As A Drying Agent Is A Bad Idea

Why Using Cat Litter As A Drying Agent Is A Bad Idea

Apr 30, 2017 As soon as this material gets wet, its physical characteristics change and the particles melt into a slimy clay mess. It is made this way to make it easier to clean a cat litter box. The wet areas “melt” and form a lump, after drying, that is easier to find and remove from the litter box. Calcining clay can only be made at much higher ...

Dec 12, 2012 Another factor that can affect your drying agent performance is residual detergent. Vehicles that have not been properly rinsed will interfere with the drying agent. Detergents are intended to decrease the surface tension and cause the water to spread over the surface, which is the opposite of what you want your drying agent to do.

Jan 14, 2017 Deliquescent dryers are similar, but involve a highly hygroscopic agent that slowly dissolves, or deliquesces, as it absorbs more water. Usually the agent cannot be regenerated, and the waste liquid is drained and discarded. Fresh drying agent then needs to be added. This is most likely the scenario for NaOH.
