The Future of this Blog

You will have noticed there hasn’t been much activity on this blog of recent times. The reason is that I think it has now outlived its usefulness in its present format. Here’s what’s coming:

1. A format upgrade to a proper website, not just a blog. This will involve a cataloguing of the Q&A section, where you’ll be able to search for topics, so I don’t get asked the same questions over and over.

2. I’m writing a book, so most of my time will be going into that. I’ll post segments of it online from time to time. But right now I’m looking for suggestions for a title. At this stage it’s going to be “Dr Chemical’s ultimate guide to stain removal” but I’m open to suggestions. A free copy to anyone who comes up with the winning title

How to Clean Kitchen Benchtops

There are lots of kitchen benchtop cleaners around, Ajax make a few, even Windex (which is probably just repacked window cleaner) are into it now.

And the reason is pretty simple – everyone cleans kitchen benchtops, so there is a big market.

The best one I have come across is BAM Oven Cleaner

An oven cleaner, you ask?

The reason is simple – grime on benchtops is normally oil or fat based, and since oven cleaners are designed to be heavy duty oil and fat removers, it’s a cinch that they’ll be great kitchen cleaners.

The BAM is particularly good as it sprays a fine caustic mist over the benchtop (unlike the Mr Muscle oven cleaner which is a foam) so you get uniform coverage.

Give it a couple of minutes to do its job, then get a ¬†wet sponge and wipe it up – you won’t believe how quickly marks and spots come off. When it dries it’ll be literally squeaky clean. The “squeak” comes from the absence of any oily films on the surface – hence the term.

BAM vs BAM vs BAM #2

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.

How do you Remove Blood Stains?

Easy peasy. Use citric acid (available from the supermarket). Sprinkle some on the stain, wet it and rub in. Don’t rub too hard – let the chemical do the work. Dab it dry, and then repeat until it’s all gone.

The chemistry of this is straightforward. The red colour of blood comes from the iron atom contained in the haemoglobin molecule. Citric acid has a very strong affinity for the iron and rips it out of the heart of the haemoglobin, thus disrupting the molecule and destroying the colour.
