Sock it to draughts with cheap 'door snakes'

With every winter, it's important to make our heating systems as efficient as possible. Draughts under doors (both to outside and to rooms not currently being used) let heat escape, driving heating costs up. Door snakes are often advertised at around $10 each. This means for a whole house you may be looking close to $100. Instead, you can use a pair of men's long, knee-high socks! These can be filled with rice (or sand if you have easy access to it). Either tie a knot or see the top to seal. You can purchase ind the socks at cheap shops or ok shops, use the cheapest rice you can buy and you can make a house-full for less than the price of one commercially produced door snake.

Re-use butcher's paper to save on paper towel

Instead of buying expensive paper towel, which doesn't seem to last in our household, we use the butcher's paper that is wrapped around purchases such as deli products to clean out oily pots and pans. This saves us money, as well as a heap of paper towel, landfill space and our precious trees!

Home mixed household cleaner

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.

Use it or lose it

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.
