I have been using the sponge to adsorb the 
stain..works wonderful.. your destaining solution 
is as clean as was before putting the gel and you 
could reuse it. Hope this helps..

Source of sponge.. It comes as a packaging 
material (may be gray or yellow).. SO in a way you 
are recycling the sponge too eh!!
