Green cleaning solutions

If you rather use natural cleaning agents, here are some ideas:

Bicabornate of soda
A must in every household. It has myriad uses around the home, just a few are given here. A a powerful natural deodorizer, it can be placed in the fridge to absorb food smells, and sprinkled on mattresses, carpets and other soft furnishings to remove unpleasant odours such as those left from vomit or sour milk. Bicarbonate of soda also boosts the performance of chlorine bleach (use 1/2 a cup of soda to 1/2 a cup of bleach, instead of the usual full cup of bleach on its own) for similar results.
A scouring paste made from half bicarbonate of soda and half water is excellent for removing stubborn stains from kitchen worktops, sinks, cookers and saucepans.
When rubbed into greasy stains on clothing, before laundering, a paste made from 2 parts of bicarbonate of soda to 1 part cream of tartar will help remove the marks.

Distilled white vinegar
Vinegar is a wonderful traditional remedy, excellent for removing limescale from a variety of surfaces and for buffing windows to a streak-free shine.
It's also a good odour-absorber, and a few drops applied to clothing faded by perspiration will sometimes restore the colour.
However, don't use it on gold-plated fittings or marble surfaces, because it is acidic and can damage them.

Lemon juice
Lemon juice is a natural bleaching agent. You can use freshly squeezed juice, but bottled stuff works just as well.
Try removing food stains from chopping boards by rubbing them with lemon juice and leaving them overnight.
Lemon juice is also very effective on rust stains, and half a cupful added to a washload will help brighten whites.

Washing soda crystals
Washing soda has been used in the home for over 100 years. It is biodegradable, contains no enzymes, phosphates or bleach and can be used on all types of fabric.
If you don't want to use strong solvents, enzymes or other satin removing products, washing soda is a good alternative. It is effective at removing grease, blood, ink, grass, red wine, tea and coffee. Soak the affected garment overnight in a strong solution (follow the directions given by the manufacturer) before washing as normal.
You can use washing soda crystals on many non-fabric satins too, such as burnt pans, discoloured chopping boards and tea-stained cups, and also for enormous variety of other household tasks, such as clearing blocked drains or removing mildew from shower curtains.
Don't use them on aluminium, though.
On fabrics, as with all stain-removing products, always check for colourfastness first.
Very important: do not confuse washing soda crystals with caustic soda.
