Multiple starters and rubber/plastic tools
I sometimes got multiple starters around the kitchen. The various jars I've gathered and use are plastic or glass and I usually favor my small rubber spatulas, which are fantastic for working with the starters in the jars.
I've read a few places about people recommending metal tools, but never found solid evidence for why. I usually clean the equipment (jars and tools) in hot tap water with dishwasher soap.
Is there any reason to worry about contamination or cross-contamination? Should I do things differently or is this way fine? I've wondered if bacteria could hide in some crevice of the rubber tools and get somewhere they shouldn't be.
