My mother is chronically ill and disabled. She suffers from a rare type of auto-immune disease, called lupus, and is therefore allergic to most chemicals. This made cleaning difficult because she was allergic to most cleaning products, or those she wasn't allergic to were too expensive to buy on my carer's pension. Because Mum's disease is an auto-immune disease, I have to keep our house hospital-grade clean.

So I have come up with a fantastic recipe, and my house is spotless, smells great and is fresh and clean. The solution cleans and polishes everything, including windows. I have never seen glass and stainless steel taps look so clean.

This solution also lasts forever. Household cleaner used to cost me $80 per month, but now I buy detergent every three months, vinegar once a year at $1.50, washing soda every 18 months at $0.98c and eucalyptus oil once every eight months at $3.50 - a saving of $880 a year minus $20 for the few items I do buy. In total I've saved around $2640 over three years.

Household Cleaner

1 litre water
200ml vinegar
40ml detergent
40ml eucalyptus oil
2 dessertspoons of washing soda

Mix all ingredients together, and it's ready to use. Use 60ml of solution in warm water to wash your floors. Fill a spray bottle and use it to clean your table, benches and bathroom.

My washing requires a fabric softener as my laundry gets hard and coarse if they're washed and dried without it, but I hate spending up to $4.00 per bottle, so came up with this cheap solution.

It works brilliantly. I now buy a home brand or extremely cheap hair conditioner (no, NOT a shampoo!) This costs $0.80c to $1.90, per 500 mls or one litre.

All you do is squirt a tiny 10 cent size dollop into your fabric softener holder, then fill up the remainder with very hot water.

I now have fluffy towels all the time, and the cheap conditioner option has worked out to be a bottle every six months or so, instead of spending lots of money per week on commercial 'fabric softeners'.

I pay myself to exercise! Now, you may wonder how that actually saves me money. Because my exercise is free, usually walking with a friend or working out to DVDs I've received as gifts, I don’t have to buy expensive exercise clothes or pay for a gym membership. And paying myself to exercise? That gives me motivation. I started with $1.00 for every day I exercised, and increased it to $2.00 a day - still cheaper per week than a single exercise class or gym membership! I wait until I have enough money for a facial or massage, and treat myself.

I find that the end goal of some pampering really works as an incentive to keep exercising. Prior to this, I never let myself splurge on those sort of things. I am now happier, healthier and far more relaxed!

Want to freeze cream without it becoming a watery mess once it's defrosted? The secret is to whip it before you freeze it. Defrost it naturally and you would never have known it was frozen.

This method lets me buy brand name cream when it’s on sale, usually as it's reaching its use by date. I whip it up, portion it off into 100ml containers and throw it in the freezer. I no longer have to worry about buying a full container of cream, then trying to think of how to use it all up before it reaches its expiry date. No more waste!

For many people juggling work, family and study, time is the most important saving they can make. I work four days a week, have a three-year-old and studied part-time for a diploma for a year. I got by with these time-saving tips:

1. Lowering my expectations for the house. I don't need a spotless house, but a tidy and lived-in home.

2. Doing my housework little and often, rather than spending huge amounts of time tidying up. I do things like:

- put my little one's daycare bag together for the next day as soon as we get home in the afternoon.
- cook my lunches (pasta and sauce, muffins and so on) once a week and freeze them.
- put my lunch box together from the freezer in the evening.
- clean the toilet by putting a teaspoon of Napisan in it each night. It soaks overnight and the bowl is clean with the next flush.
- do laundry when enough for a load accumulates so we don't have a sudden clothes drought, then an avalanche of laundry to do and put away.

3. Exercising on a stationary bike in front of the TV in the evenings after my little one is in bed.

4. Programming our DVD recorder once a week (Sundays when we get the new TV guide) so I don't miss my favourite shows.

5. Filling cereal bowls with water if I am rushing and have to leave the breakfast things. This makes them easier to clean later and stops ants.

6. Trying not to double handle things. Rubbish goes straight in the bin, meat is put in meal size portions in plastic bags and frozen as soon as it gets home, magazine subscriptions go straight to magazine rack when they arrive in mail.

7. Leaving rooms better than when I arrived, so the need to tidy doesn't build up. It only takes five minutes to put laundry from the floor to the hamper, make the bed, wipe a bench, replenish the toilet paper.

8. Recruiting my little one to help - she's only three but she can put dirty dishes in the sink, put toys away in her room, dirty clothes in the hamper.

9. Shopping for groceries by myself in the evening so hubby can watch his TV shows in peace and I am not tempted to go to other stores as only the supermarket is open. Also many things are marked down at that time.

10. Trying to do three things for myself that make me feel happy each day, like listen to podcasts while I do the housework.

11. Writing the shopping list progressively through the week so I can pick it up and go when it's time to do groceries.

12. Storing the bedding in storage containers under each bed so it's quick to make the bed, especially when changing my little one's wet sheets in the middle of the night.

13. Shopping for presents at sales during the year (online or in stores) so I don't need to go to crowded stores during the Christmas rush.

14. Not beating myself up if I find lifestyle changes tricky at first - I am afterall human!

I am a young woman on a single income, paying off my homeloan. I know the amazing financial savings that are possible when you make extra payments of any size on a large loan. However, because I am on a low annual income I often find it very hard to find any spare cash after all the bills have been paid.

So for birthdays and Christmas, when my friends and family are seeking ideas for gifts to give me, instead of asking for things I don't really need, I ask them to deposit the amount that they would have spent on a gift straight on to my homeloan. I am very close with my friends and family and they understand my financial situation. They are only too happy to help me get ahead and hopefully one day own my own home. It is a gift that keeps giving and one I truly appreciate. I read recently that for every extra $1.00 you are able to pay against the principal of your homeloan you will save $2.00 in return and take years off your loan. The understanding and generosity of my friends will help save me tens of thousands in interest over the years.

This idea is for those who live in a home with a garden that is too small to have a compost bin. I use an empty garden pot, cut a square of one of those net bags oranges come in to cover the hole of the pot. Put in a layer of old potting soil (from a pot where the plants have had their day). Each day save your fruit and vegetable scraps in a container. Place in a layer of scraps, then cover with another layer of old soil. Repeat layer by layer until the pot is nearly full, ending with a layer of soil (water as you go).

Then, while the compost is breaking down and baking, plant some seasonal seedlings on top and in no time you will have potted colour and compost underneath, not only feeding your seedlings but ready for the garden when the flowers are spent at the end of the season. I sometimes benefit from crops of vegetables germinated from the seeds in the compost such as tomatoes, cucumbers, capsicum and butternut pumpkin.

This is a multi recycling exercise using unwanted orange bags, unused pots, old soil and fruit and vegetable scraps and, of course, it is a great medium for the latest seedlings. Instead of flowers on top you could plant your favourite herbs while the compost is baking.

As part of my $21 Challenge to use all the food in the pantry, I have set up a 'use up soon' basket containing items getting close to their use-by date. This way, I will remember to use things before I have to throw them out.

We decided to get rid of the $96,000 mortgage on our home within three years. The massive load of interest we would pay to the bank was over the top and we felt that the bank owned us. The entire family bought into the project one hundred percent.

1) We replaced the nice modern cars with older, less costly ones. The net difference and any savings we had and $700 from a garage sale were paid off the mortgage.

2) We agreed to budget as if we were in a life and death war and the war had to be won in three years. I developed an Excel budget spreadsheet and we tweaked the numbers until we had a 'do-able' weekly saving of $220 extra to pay off the mortgage. Clothes purchases would be done exclusively at 'Harrods', our Salvation Army shop, until the war was over.

We decided to run any item not budgeted for over three 'hurdles'.

The first hurdle was 'could it shorten the mortgage war?'

The second hurdle was 'is it a health issue?' and if so what was the least-cost workable solution?

The third hurdle was 'could it wait until the end of the three years?'

3) As time progressed we became pretty smart at reassigning money to reward ourselves for enduring the war. This meant we could have a low cost take away sometimes, or spend on an out of budget item we had set our hearts on.

It took nearly four years to knock off the mortgage. Yes, we won the war a little later than hoped, but we won. If it had taken eight or nine years to win, it would still have been worth it.

The legacy of our war against the mortgage is that we have developed great money saving skills for life. And life is great.
