I have a styrofoam hive top feeder that got mildewey. Any suggestions on cleaning styrofoam?
Scalding hot water and a soft wash rag will take it off fine. A little vinegar in the water might help a bit.
Great! Those three things I have in abundance. I'll give it a whirl. Thanx!
Another option is to wash with the hot soapy water and then spritz it with a mixture of 1 part peroxide and 2 parts water from a spray bottle and wipe out after it quits foaming to kill anything that the soapy water didn't.
