High-Density, Strong Water Absorption – Car Washing Sponge 

High-Density, Strong Water Absorption – Car Washing Sponge Product Overview During car washing, the water absorption speed and water retention capacity of the sponge directly affect washing efficiency and paint surface safety. Sponges with slow absorption require repeated dipping, extending washing time. Sponges with insufficient water retention capacity lose moisture quickly during wiping, which can lead to dry wiping on the paint surface and increase the risk of scratches.
