A year's worth of cleaning product for $7.50

I saved $1900 in a single year with this recipe for a great all purpose spray cleaner! It is suitable for all kitchen surfaces, tiles, bathrooms, toilets, even stainless steel kitchen appliances and cooktops. The only thing I'm not sure it's suitable for is marble benchtops. Here's how you make it:

In an empty 600ml spray bottle, combine one tablespoon of full strength eucalyptus oil and one tablespoon of sugar soap. Fill the bottle with water, turn gently to mix, then simply spray and wipe as needed.

The eucalyptus oil cuts through all grease and is also a cockroach deterrent and an anti-bacterial agent. In the bathroom, I spray all bath/shower surfaces and then scrub with a clean, wet broom. As a floor cleaner, I spray it on the really dirty bits, then use a steam mop over the top.

Before I started using this, I used to spend $4.00 per 500ml bottle of Ajax Kitchen Cleaner, $6.00 per 500ml bottle of Ajax Bathroom Cleaner and $8.00 for a 250ml bottle of special cleaner for the stainless steel cooktop and oven. I was replenishing all these every two months. That's $18 every second month or $1944 per year!

By comparison, I have calculated that my recipe costs $0.79c per 750ml bottle, and I make a new batch about once a month. That's a grand total of $7.50 a year. What a saving!
