My mum and step-father used to make their own laundry detergent, known in the family as 'gloop'.
After the large supply of commercial powder that Mr Trifectagirl was finished some 12 months after he got sick - he'd bought a lot - I started making gloop again as a budget measure.
1 cake of pure soap
1 cup washing soda
1 tsp eucalyptus oil
20 or 10 litre plastic container, old cheese grater, old saucepan (4 litre a good idea)
Time to make: about one cycle of my washing machine - probably about half an hour, but I really haven't watched the clock.
Heat 2 litres of water in the saucepan.
While the water is heating, grate the soap (this is a PITA job - I can't wait until J is old enough to help).
Add the grated soap to the saucepan and bring to the boil - watch it as this has the ability to over boil like milk. I upgraded to a large stock pan that I found at a second-hand store for this batch after getting jack of cleaning over flows up, and I still had a mess to clean up.
I usually add the extra water to my bucket at this time (see quantity below).
Add the soda and stir until melted. Forewarning - the soda will cause a reaction that could result in an over-flow if your pan is too small (my old over flow problem).
Pour the mix into your plastic container, and add the eucalyptus oil, and stir to mix.
For a 20 litre container, add 9 litres of hot water and 8 litres of cold water - this results in a claggy mix and use 2-4 cups per load.
I use a 10 litre container and add 3.5 litres of hot water and 4 litres of cold water. This mix sets pretty solid and I use about 2 cups per load.
I find this mix lasts a month or so, and at a rough, back of the envelop calculation costs $2 per bucket to make using higher quality ingredients.
And the best thing about the new pot - all my bits and bobs for making gloop fit in it. I can put on the lid and put it away until next time.
