Cleaning salt from smart pots - Good ideas?

[McCdive]

Hi, all!
I've been looking around, and I haven't found anything on cleaning smart pots. After several grows in all my pots, I have a fairly good buildup of salts +? built up on the bags. I don't want to use anything that will leave a bad residue on them and ruin a grow!
Does anyone have any good suggestions for me??

Much appreciated, Friends!!
Andy.

Try soaking in 50/50 water and white vinegar. It will brake down the salts.
