Make Good Use of Waste Materials

I saw a tip on
the internet about using shaddock peel to make dishwashing liquid, in
recent days when I got nothing important to do. There are some
shaddocks left, which are brought during Spring Festival holiday. So
I just try to make dishwashing liquid by myself, according to the
progress on the internet.

First, I’ll
introduce needed materials, which is really simple: Shaddock peel,
dietary alkali and a utensil.

Like we see,
these are all materials we need. The things we need are quiet less.

I scratch lines
on the shaddock to prevent the fruit pulp from hurt.

Due to these
lines, it is easy to peel the shaddock with hand. One of the benefits
of doing so is that the pulp wouldn’t be dried if we couldn’t eat
up.

Then we can
take out the pulp from peel with hand.

Whittle half of
the white part inside the peel.

Cut the peel
into strips.

Put these
strips into the glass pot, approximately two thirds.

Pour tap water
into the pot. It is appropriate to submerge these strips.

Add about a
spoon of dietary alkali. I can’t find a spoon, so I just pour it in
the bottle cap. If you want stronger degreasing effect, you can add a
little more.

Cover the lid
and shake up.

Put the jar in
refrigerator for about a week.

After a week,
the self-made dishwashing liquid is done.

You can smell
fresh grapefruit flavor when uncover it, which is really good.

Pour out some
self-made dishwashing fluid. The color of it is slight yellow.

With the help
of kitchen towels, food oil which tends to unmovable can be removing
easily.

I take a test
in particular. This is the bowl and scoop just used, and the effect
is not bad.

Summary:

It can make a
good use of waste materials by using the left-off peel of shaddock to
make dishwashing fluid. It indeed has a scientific basis. There is a
kind of compound in the peel of shaddock, which is similar to the
surfactant in abstergent. It has good adsorption and dirt-removing
capacity. After the soak for several days, this kind of compound can
dissolve in the water and enforce the cleansing power of dietary
alkali. Food-grade lye can hurt skin to some extent, but the planet
oil in the peel of shaddock can protect people’s skin. And this can
ensure the self-made dishwashing liquid is gentle to hands.

Advantages: no
chemical material, gentle to hands, cleaning effectively, slight
fragrance of grapefruit after washing.

Disadvantages:
the time of producing is a little long; it has to be stored in
refrigerator to prevent dishwashing fluid from going bad.

If you happen
to have left grapefruit peel, definitely you can have a try to make
good use of wastes.
