Last week on 6PR Shannon Lush gave us her tips on cleaning in response to listener questions.
Are her tips right? Will they work?
Let’s look at it.
The first thing that needs to be understood is that Shannon is not a chemist. She doesn’t know much chemistry, and has little understanding of the chemistry and principles behind off-the-shelf products. The result of this is that whether her home-spun ideas work or not, there is usually an off-the-shelf product that will do the job just as well, or better, saving you a lot of time, and often money. She is not able to recommend these products, as she does not know what is in them, nor how they work.
Let’s look at the questions one by one.
The first caller wanted to know how to get sunscreen stains out of a white t-shirt.
Shannon’s answer was to use a dishwashing detergent as a spot cleaner. Put some detergent on the stain, close your eyes, and rub it in. When you feel the detergent thicken, this is caused by the detergent emulsifying the stain. She was not able to name a particular brand to use.
Is that why it thickens? Possibly, but the thickening will also be caused by the water in the detergent evaporating, and the thickening agent therefore being present at a higher concentration. She is clearly not aware that most dishwashing detergents are about 80% water, and the thick consistency is caused by a thickening agent to disguise this fact.
So will it work? Probably – but use Morning Fresh, as it has the highest concentration of surfactant (40% last time I looked).
Alternatively you could use acetone, which would probably work instantly.
If neither of these work, try Easy Off oven cleaner. Spray on, rub in and rinse. If that doesn’t work, try a powder laundry detergent, preferably one with enzymes. Make the powder into a paste and rub it on and rinse.
The next question involved gravy stains in microwave cookware. Shannon was not able to answer this, but merely advised the listener how to protect the cookware from being stained in the first place. Fortunately, I can answer it. Put some washing soda in there, make it into a paste by adding a minimum amount of water to it, and rub it into the gravy stains and it will come out.
The next question was about cleaning and maintaining leather car seats. In particular, the listener said that the product he was using left the car seats a little sticky. Shannon’s answer involved a concoction of lavender oil and a couple of other things. I haven’t tried this myself, because I don’t need to, as there is an off-the-shelf product that is a terrific leather cleaner and conditioner – Mr Sheen.
Originally marketed as a furniture polish, the people at Reckitts finally realized what I have known for years – that it is s terrific general purpose cleaner, and particularly for leather. It has just enough white spirit to clean grime off seats, and leaves a silky smooth silicone coating that leaves your seats smooth and shiny. It’s also terrific for sprucing up your dashboard, paintwork and engine. Spray it on the outside of your windscreen and it’ll help the raindrops run off and your wipers glide smoothly. But don’t spray it on the inside of the windscreen as it’ll promote fogging.
The final question involved a brown stain on a carpet. Shannon told us that it was caused by tannins that leached out of the carpet lining. Unfortunately, it doesn’t require a whole lot of analysis to see that this is completely wrong. She would have us believe that carpets contain a water soluble, brown substance in the lining, and all that has to happen for the stain to appear is for the carpets to get wet. Somehow I think that the people that make carpets are not quite that dumb.
I don’t know what the stain is, but I’d hit it with an enzyme cleaner (WhiteKing Stainlift) and if needs be, an oxidiser (Preen OxyAction). There are other more aggressive approaches if required – check the Q&A section on my website.
