A few months ago I read the washing instructions for RARs. They say use whatever to get them clean basically. They even suggest using a detegent like tide with enzymes. I haven't yet but am tempted to try them just because I won't be voiding the warranty with the way I wash. Even though I haven't really wortied about that anyway.
I would like to blame my phone for all the typos but in reality the poor thing is just trying to keep up with my crazy thumb typing while holding a baby.
