i don't drive a taxi. i just share some tips of purifying
the surroundings with you:
1. Used coffee powder
-- For coffee powder bag, after you make your coffee don't throw
away. Used coffee powder is known to absorb any foul smell.
We always put used coffee powder bags in our refrigerator so
that it will absorb those fish, food or durian smell. It can
also absorb smellyness from the shoe cabinet.
-- If you used coffee powder by itself, then find a porous bag to
collect the coffee powder in it and place it.
2. Fresh Orange and Lemon peels
-- After you eaten your oranges and lemons, leave the peel
and the peel will emit the natural fruityness. It last for
about hours before drying out and losing the scent.
3. Indian Incense or Japanese Incense
-- If you don't mind Indian fragrance, then Indian Incense is
a very good choice for freshening the air. Do not need to light them up.
Just get one or two boxes of Indian Incense from Indian
shops, tear open the plastic wrapping inside, allowing
the Incense sticks to let off the fragrance and leave the box open.
This method is good for an enclosed space. For us, we
usually get the Lia Incense (one package consisting of 12 boxes
consisting of Jasmine, Samtrupti, Chandanam, Prime Rose, Rainbow,
Spice World, Sea Shore, and Nature's Gift). We put in book
shelves and all the books become nice smelling. These incense
are hand-wrapped, and they help absorb the surrounding moisture
too. By far I like the nicest smelling Samtrupti (meaning
mixed fruits), Nature's Gift (mixture of lily and geranium)
and Jasmine. The rest are also equally
good.
-- If you don't like or not used to Indian fragrance, the
next choice would be Japanese Incense stick though they are not as
powerful. I use a variety of brands from Koubunboku, Kokonoe and
Shukoukoku.
-- Poor quality Chinese Incense commonly used in homes and
temples doesn't work
4. Overly toasted bread
-- Regarding bread, it should not be only a normal loaf of
bread. If you find slices of bread which is expired, toast it
into Chao-Ta state with your toaster. Only Chao-Ta bread can
absorb smell from the surroundings.
Some other methods that I heard before are Lemongrass heated dry
with Microwave Oven can absorb smell, and Washing Powder put
into a box and poked holes on the cover to absorb moisture, can
last for 2-3 months and later on still can use it to wash clothes,
no wastage.
