Bunnings are now selling a new power scrubber for the bathroom, and particularly grout. It appears to be essentially an electric toothbrush with a stiffer brush.
I’d spray some oven cleaner on the grout first, however, as that will loosen the grime, and it will come off easily
The right selection of chemical product is critical to cleaning a surface well. But in recent times, a number of products have come onto the market that rely on their physical properties to do the job.
The best one of these that I have seen is Lint Magic. The principle is pretty straightforward. We have all seen sticky rollers for collecting pet hairs, dust and lint. The sticky roller gets full, and you just peel a layer away to expose the next layer of sticky paper and so on.
But the Lint Magic is even simpler. The roller is a soft silicon material that is sticky. After you roll it on a surface and collect dust or lint (it’s a great spot cleaner for floors) you just wash it under the tap, and all the lint just washes off. As soon as it dries, it’s right to go again – of course if you’re cleaning a carpet you don’t even need to wait for it to dry.
All in all, it’s a very clever product.
BAM make an oven cleaner:
It’s a pretty good oven cleaner, but there’s something it’s better at – a laundry prewash or spot cleaner for oily or fatty stains, whether it be cooking oil or engine oil.
The reason it works so well is that unlike the noncaustic Mr Muscle oven cleaner, it comes out as a fine spray. It can be worked into the stain and rinsed out, or simply sprayed on and used as a prewsh. But wait at least 10 min to allow it to react before washing it. Let the chemical do the work.
Soap scum isn’t easy to remove.
It’s a baked-on alkaline salt from soap and calcium and sticks to the glass like glue.
To get it off you need an acid – but not too strong or it’ll dissolve the alloy beading in your shower.
I remember one day I was browsing in the cleaning section of the supermarket, and I was bemoaning the fact that no-one seemed to take shower cleaning seriously.
“Why” I asked myself “don’t people put sulphamic acid in these things?”
Sulphamic acid was made for cleaning showers. it’s almost, but not quite, strong enough to dissolve alloy, but is certainly strong enough to dissolve soap scum.
Then I came across this:
Anyone in the supermarket watching when I read the ingredients would have thought I was nuts because I went “YES – sulphamic acid!”
It’s actually quite unusual to see a cleaning product that uses a completely different formula to its competitors.
But this is one. It’s competitor – AJAX – uses phosphoric acid: which is nowhere near as effective.
But the people at Reckitt’s have sure got this one right, which is why it’s one of my favourite products.
How much detergent is there in a dishwashing detergent?
Well, not as much as you might think. When we squirt them out, the thick liquid gives the impression of being quite concentrated. But, sadly, it’s a trick. In other words, an “impression” is all it is.
The reason that they are thick is simply because thickeners are added. These remarkable products (often clays) are what turns hair gel into gel, and are present in almost every “thickened” cosmetic product. Present as only a couple of percent, they can convert a water like substance into a honey like substance or even a gel.
And in the case of dishwashing detergents, water is mostly what it is. Most brands contain only between 10 and 20% detergent. and the el cheapo generic brands are down below 5%.
The standout performer however is Morning Fresh by Cussins. This product contains about 40% detergent (last time I looked) and is the only brand that can justly attract the label “super concentrate.”
So if you are buying any other brand of dishwashing detergent than Morning Fresh, you’re being sold short.
