RE: Sodium Carbonate

I do know that detergents often contain fabric "brighteners" and
who-knows-what additives. If you need only s. carbonate, it is fairly
cheap. I use it to bind dyes to fibers -- it starts the reaction. It WILL
weaken fibers and eat away and your clothing -- I hope that's not what
'washing soda' is!!! But then, short exposures to it are not as bad as
soaking something in it, of course.
