Full strength DIY 'Dettol' spray for just 2c a bottle!

A little supermarket research led me to making a huge saving on keeping germs at bay! When my two young children had a gastro bug, I needed anti-bacterial spray to clean up and stop the spread of germs, which vinegar didn't touch. The cheapest anti-bacterial spray I could find was Dettol anti-bacterial spray which cost $4.20 for 500ml. On reading the active ingredients it said it contained Benzalkonium Chloride 0.095%. Then, I saw that a bottle of Coles brand disinfectant was $1.40 for two litres. I read the ingredients and saw Benzalkonium Chloride 1%. The instructions said to dilute it in a ratio of 1:20, or 30ml to 600ml water. So I bought that one, made up the solution and put it in an old spray bottle I already had. It worked just as well and cost just over 2c per spray bottle of prepared solution, compared to $4.20 for the Dettol spray! While Coles brand disinfectant says it can only be used on “floors, walls, bathroom and toilet areas”, not in kitchen areas like the Dettol spray, for me these were the only areas that I needed to disinfect and worked a treat!

Many meals from one rolled roast

I have found a way to get maximum meals and value from one single rolled roast. I bought a rolled pork roast which was way too big for just the two of us. Not wanting to be living on leftovers all week, I decided to cut it in half before cooking it. As I was about to place the uncooked half in the freezer, I decided to cut it into thinner slices and use the meat as pork chops instead. This has worked well! I also plan to cut the rolled roast into chunks in future, to use for stir fry, sweet and sour pork and so on. Normally you could never get pork chops or stir fry for $7.99 a kilo! There's no reason why you couldn't use this method with other rolled roasts too.

Freeze your own grated cheese

To enjoy the convenience of pre-grated cheese, buy a block and grate your own - much cheaper than spending money on those costly supermarket bags!

Buy a block of cheese, grate it into a large ziplock bag and add a rounded tablespoon of cornstarch to the bag. Shake well.

This keeps the cheese from sticking together in a lump and you can store it in the freezer for as long as you want. It thaws almost instantly!

A Challenge for life

After reading The $21 Challenge, I thought I would see which other areas of my life I could apply the Challenge to.

First, I opened a separate bank account and now deposit $21 every week before I do anything else with my money. I see this as a type of retirement fund – it will be nice to see the funds in 30 years time!

My next $21 Challenge is to only put $21 worth of petrol in my car each week. I will park my car further away from where I need to go; this will save money and improve my fitness and wellbeing.

When my phone contract ends soon, I am going to challenge myself to spend no more than $21 on pre-paid phone credit each month - now that will be a challenge!

There are so many ways we can implement the $21 Challenge in our lives, thanks to Fiona and Jackie's inspirational book.
