Before buying expensive household cleaners, use the following:

White Vinegar
All purpose household cleaner, use with lemon and hot water to clean dishes and surfaces from stone floors and benchtops, to toilet bowls and basins. I recommend 25% vinegar to 70% water and 5% lemon. If you like vinegar then put as more as you like. However, vinegar is an acid so don't use it on your silverware or any expensive cutlery that you will be very sorry to ruin. Don't use it with jewellery. Pearls shrink and lose their nacre if you leave it in vinegar.

Lemons
If vinegar is too strong use FRESH lemons instead, not the lemons in containers you buy at the supermarket. Mix with hot water to freshen up smells. Put a slice of lemon in a glass of water and place it in the fridge/windowsill to get rid of odours. I have seen jeweller shops put this in their window fronts.

Lavender Oil
Put 2 or 3 drops of this on your bed sheets for that lovely smell. You don't want too much as it will reek. Instead of buying expensive drawer liners, again place a drop or two of lavender oil and your drawers will smell nicely.

Olive Oil
Use as a lip balm, getting rid of dry skin, drinking a tablespoon to get rid of incessant coughing, smoothing hair (not too much you don't want it too oily!) and generally a good moisturiser.

Cleaning a Leather Jacket

Eucalyptus Oil
An excellent way to get rid of chewing gum on carpets, clothes etc. Also I find putting 2 or 3 capfuls of  the oil in my washing helpful in disinfecting my clothes and making them smell nice.

Bananas
Use the peel (the inside) to polish your leather boots and shoes. Not recommended for suede but can be used for vinyl. I found myself using the banana peel to polish my new Italian leather boots and they worked magnificently. The only drawback is that the peel does tend to brown quickly and if your boots have seams and stitichs then the banana peel will leave some crusty brown marks which are easily removable.

Experimenting
Make sure you try a small patch of cloth or cheap plates or cutlery to see if the cleaning works.
 
Good luck!
I am allergic to dustmites and most cleaning chemicals. I find that using air fresheners and cleaning products make me sneeze immediately. However, using  the above materials  have not had the same effect. So good luck with  your cleaning experiments. Think of the packaging  that you will save from going into the landfill (it's ridiculous how a toilet cleaner can now be wrapped in paper within a plastic within a plastic!) and  your  hip pocket!
