Making your own laundry washing powder - its easy!

I have been reading about making your own washing powder on the net for a while. There's a good discussion going about it over at Earth Garden, and Cheapskates also have a lot of information MYO washing powder as well. I talked to my husband about it and he wasn't keen. (He's a bit fussy about his washing - and that's why he does the washing in this house!) and so I left it. For a while.

One afternoon I decided that I would give it a go as we were running low on washing powder and made some and plonked it on top of the nearly run out commercial stuff in the laundry.

He didn't notice a thing!  

Until I made a batch with yellow laundry soap instead of white bathroom soap. And it was only the colour that gave it away! He decided that since it had obviously been working and he hadn't seen any adverse effects on his work shirts thus far - I was "allowed" to continue! But now he gets involved and is happy to make up a batch when we are getting low. It is defiantly cheaper than the commercial stuff, does a good job and has less perfumes and fillers in it. I'm also happy to run the washing machine water onto the gardens as I know whats going down the pipe!

Here's what I did...

For this batch I used (just) 2 bars of old laundry soap (that were stuck together until after I took the photo!) 1 kg of washing soda (not crystals, these dissolve quicker) from the laundry isle of the supermarket (top shelf - about $3.50) and 1/2 packet of bi-carb.

 First - grate your soap - it looks like cheese... don't let the kids pick at it...

Then crush the soap into a fine powder with the bottom of the grater. The finer the soap powder, the easier it will dissolve, especially if you use cold water for your washing. The older the soap the more dried out it is likely to be making the crushing easier. If you use new soft soft, it can be grated into beautiful curls - that mash rather than crush.

Here you can see the difference between curls and crushed soap.

 If you think the soap is to soft and not crushing into a powder - simply dry it out. Here I have crushed it as fine as I can, spread it out on a board and then left it in the sun for the day on the picnic table. If you put curls rather than crush into your mix, you will get undissolved soap curls stuck on your clothes when you pull them out of the wash. Not a current fashion look I've been told!

 That's all the hard work done! Now you simply put all your ingredients together in a suitable container (an ex-cake box with a broken lid in our case)

 Mix together!

And use in the normal manner!I know other people add fragrances, borax, and other bits and bobs to their mixtures but I keep it simple so that its quick, easy and replicable.
The soap powder is what does the cleaning - as soap does in its usual application. If you use a scented soap you will get that scent through your wash. The bi-carb is the deodoriser and the washing crystals are the water softeners that help to remove stains and grease spots.

We have been using this recipe for a few years now with no problems. The grey water goes into the garden beds and even the plant seem happy with this mixture!

Score card:
Green-ness: 5/5 for making your own without the extra unnecessary ingredients.
Frugal-ness: 5/5 for making it much cheaper than the commercial stuff.
Time cost: About as long as it takes you to grate the soap - for me, about 3 minutes.
Skill level: Super-duper easy!
Fun -ness: Great fun to make something that looks bought, acts bought but isn't!

Hi Kara, love the blog found it a couple of days ago, quick question about using the grey water, can you use it on veggies and fruit trees too? Ta Jackie

This is one of those "grey area" (if you'll excuse the pun!)The local council forbids it, waste water isn't allowed to go near edible foods and is only allowed to be used on ornamental plants. I have some grey water going onto some lemon trees occasionally and since the part that I eat doesn't come in contact with the water, I reckon its ok. I'm reluctant to say "Yes, go ahead and use it" as that's not a responsible thing to do, but as this doesn't have anything terribly harmful in it, I personally cant see the harm in it - however health and government bodies feel differently (and I'm not allowed to encourage you to break the law!) Try it and see what you think! - K x

Killing cockroaches with boric acid v borax!

We live in Queensland. We have cockroaches. Lots of cockroaches! Why the NSW rugby team is called the Cockroaches is a mystery to me - surely ours are not only bigger but more plentiful??? At any rate, I don't like living with them (and I'm quite sure they  are not so fond of me at the moment!!) and I have been going through the usual gauntlet of sprays, solutions and bombs to get rid of them...

But I'm not so keen on the chemical aspect of all this spraying and bombing. I hate the smell and can almost feel disease and cancer growing in me every time I spray. I'm OK with the resident cockies getting a lungful of chemicals and then keeling over but I feel its impolite (and probably illegal) if my guests and family members do the same thing!!!

We went through a faze of killing them by hand (and flyswatter and rolled up newspaper and underfoot) but its hard and frustrating work and it probably was only culling the dumb and slow ones - leaving the smart fast ones to breed!!!

What to do when your cat attacks a bird... and doesn't kill it.

We have an eight year old cat who we got as a stray about six years ago. The vet reckoned she was about two when we got her and we did all the right things and got her spayed and vaccinated and all that stuff. She loves people and no matter where you are in the house or garden, she will not be far away. She really good with kids and will put up with the squishiest cuddles and a far bit of toddler tail fascination before bolting out the door to escape. She is well fed (despite the look she is giving me and the empty bowl below...) but not fat - but still the  urge to hunt and subsequently kill still seems to be quite strong.

Last weekend, she pounced out of nowhere on a rainbow lorrikeet - thankfully my husband and a band of teenage boys were also there and managed to grab the bird before the cat had done more than pounce. Now we have a slightly mangled still alive but obviously unwell bird on our hands - what do you do?

Here's what we did...

We found a box - popped an old towel in t…

Refilling old candle holders with new home made candles!

I had a number of nice wee candles that had burnt down to the bottom of their containers. They were too nice to throw away and I decided that I might be able to refill them with some more wax that I had lying around and use them again. Jumping straight in as I am apt to do.... I learnt a bit about candle making the hard way!

Here's what I did...

First I gathered up all my old wax. I scooped the wax out of old candles by either melting it for popping the whole container in the freezer for 10 minutes or so - most of the wax just popped out of its container after that!
I bought a length of candle wick from my local handcraft store. This was 6 meters and cost me $4.
I used the double boiler method of melting all my wax together. I used an old tuna can as I was only planning on filling four small candles. Don't let any water boil over into your wax. It will make your candles go funny...
I gently stirred the wax as it melted.
I measured the depth of the candle holders and then doub…
