Chemical Keeps
Boiler Free
From Rust
BY HILSON MUNSEY.


This winter the heating problem
Is likely to be more serious than 1t
has been at any time in the last
quarter of a century. The fuel sup
ply may be limited by the needs of
the defense program and the more
one can economize on fuel the
greater will be the contribution to
the national program. One way OF
doing this is to see that every pos
sible unit of heat is utilized by haV-
ing a perfectly clean heating system.
One of the obvious things to do
Is to see that there is not any &C
emulation of SCOT on the surfaces
of the boiler that are exposed TO the
heat of the fire. Another is to see
that there is no accumulation OF
rust inside the boiler. The removal
of this rust need not be a dill
ficult matter There is prepara-
ton on the market that can be put
into the boiler by the owner HIM
self. which will remove the rust and
scale that prevents the water IN
either a steam or hot-water system
from receiving the full benefit OF
the fire.
Removes All Rust.
It is a chemical preparation that
will clean the system without drain
ing or flushing. This chemical re-
moves the rust by reducing 1t 10
gases that will disappear without
trace, leaving nothing but a timely
divided residue that will circulate
with the water without being de-
posted on the sides of the boiler.
It also acts to prevent the ac-
cunulation of scale produced by
the lime in hard water, and it also
will eliminate any oil left in the
pipes or boiler by the plumber when
the installation Is first made, or
when repairs have become necessary
The surface of the water cannot
become coated with oil that causes
printing and foaming, which reduces
the effectiveness of the heating sys-
tenn so much. A quart package OF
the material is sufficient for the
average home and the price is small.
To put the preparation to work
a fitting above the water level IN
the boiler must be removed. Any
one will do. 1t may be the safety
valve, the pressure gauge or the
souare-headed plug that Is found
in some types of safety valves. Be
fore the fixture is removed the fire
must be allowed to die down so that
there Is no danger of being scalded
by steam.
Then the mixture is poured into
the boiler. After replacing the flt-
ting that has been removed the fire
is drawn up in the normal manner.
After a few days of ordinary oper-
alton of the heating system the
water in the boiler will be clear and
the boiler will be rustproofed for
the remainder Of the heating season.
II the rust condition Is excep-
tionally bad it may be necessary to
draw off the water from the furnace
after the chemical has worked for
a few days to get rid of the accumu-
lation Of particles that have been
dislodged by its action.
Basement Floor Paint.
The floor of the basement, usually
of concrete, is one of the most dif-
ficult painting jobs in the house.
Ordinary paint won't work because
there generally is lime in the cement
in sufficient quantities to destroy 1t
and enough moisture seeps through
the porous cement to make the
paint peel off the surface. Some
thing else is needed and there are
a number of paints on the market
that have been developed specially
for this purpose.
This particular one is made by
well-known manufacturer. 1t is
alkan and moisture proof and highly
resistant to acids. 1t will form a
hard surface-even on green" ce-
ment If the surface is etched. 1t
will not soften either with moisture
underneath or condensation. Neither
gasoline nor mineral oils will af-
feet 1t.
1t dries to an eggshell gloss that
Is easily cleaned and it can be used
out of doors as well as inside. More
over, it's uses are not confined to
cement. 1t can be used on wood or
metal Just as successfully. 1t is not
intended to Withstand hydrostatic
pressure. That requires consider
ably more than an application Of
paint.
Before applying this paint the
surface to be covered must be free
of grease or wax and any old paint
on the surface must be removed.
The cement must first be etched
with a solution of one part of
muriatic acid added to five parts of
water. The paint reaches its maxi
mum hardness in about week, but
is safe for light traffic within "a
hours. The paint is made in four
colors-tile red, gray, brown and
forest green.
