Description : Does a Spongetech sponge work as advertised?
Last Answer : The website says the car sponge [for instance] is good for up to 8 washes. That counts in the fact that when you squeeze the sponge, soap washes out. You would be better off with a normal sponge and a ... of soap should last you about 6 months of car washing [if you wash your car 4 times a month].
