Shannon Lush gets it wrong #7

Shannon Lush once again regaled us with her advice on home cleaning on 6PR on Monday.

One listener called in and said that he had a shirt that had one white sleeve and one black sleeve. He wanted to know how to wash it such that the brightness of the white was enhanced. Shannon’s answer referred solely to the washing temp, and suggested that if the water was “blood temperature” that this would achieve the desired result. This answer is partly right – with modern detergents warm water produces optimum results. But the point is that such a detergent is required. Premium brands such as OMO or Biozet contain optical brighteners that not only will make the white brighter, but will also make the black a more vivid black.

Next a listener wanted to know how to get a wasp nest off the cement rendering of his house. He said that he had used high pressure to remove it but it hadn’t worked. Shannon’s answer was, firstly, that high pressure cleaning only “forces dirt in further.” I’m sure this information would be news to the many businesses that use high pressure water to clean houses and driveways. We were then told that the wasp nest would release endorphins. I think she meant pheremones – endorphins are the natural feel-good chemicals that your body releases as a response to intense exercise.

The advice to use glycerine/tea tree oil to dislodge the nest is sound, however. Glycerine has pretty good stain removing properties due to its de-facto surfactant structure. But caustic soda would work better. Spray the nest with an oven cleaner, wait half an hour or so, and then blast with the HP cleaner and it will come away.

Then came a pantry moth question. Shannon’s answer was to use Bay Leaves, as they “release enzymes that render moths sterile.” This sounded a little far-fetched to me, but I don’t know everything so I investigated. I asked Bryce Peters, a well-known entemologist at UTS in Sydney.

His verbatim reply was:

I have not heard that one. I know some people claim Bay leaves repel moths. I have not seen any evidence of that.
