In the soap room we lay towels down underneath our molds, so that when we pour the raw soap into the molds, any spills land on the towels. It had been quite a while since the towels were washed and they were pretty covered in soap. So when I put them in the laundry, I didn’t add any laundry detergent.
It didn’t matter – there was still too much soap.
It took 3 washes to get rid of all the suds.
