Cleaning upholstery
When attempting to rem ove stains from fabrics of any
kind it is recommended that the area adjacent to the
stam n first be moistened with the solvent before working
on the stam n itself. Otherwise, a soil ring may be left
around the cleaned spot.
Specific stains
Grease, ou l and lipstick can be removed with carbon
tetrachloride. Large stains are best dealt with by moisten-
ing in the normal manner and then pouring solvent over
the entire stam n and soaking it up with blotting paper.
Chocolate, ice-cream, fruit and vomit stains should be
treated initially with lukewarm water, possibly with the
addition of a little soap solution. Af ter dry ing, any residual
stains may be removed with carbon tetrachloride.
Battery acid should be treated instantly with large quan-
tities of cold water, as otherwise the acid may burn holes
in the upholstery. If possible, add a few drops of ammo-
niac to the first water.
Blood stains should never be allowed to dry, but should
be removed immediately with cold water.
Unidentified stains
Try the following solvents in the order named:
Cold or lukewarm water
Lukewarm soap solution
Before making further attempts, remove the soap solu-
tion with lukewarm water and allow the material to dry,
since the following solvents are not miscible with water.
Conti nue with
Carbon tetrachloride
Trichloroethylene
Pure gasoline
R ub the spot while the solvent evaporates, first hard and
gradually more gently as evaporation continues.
Do not forget the initial moistening round the stam. The
bigger the stam, the bigger the area to be moistened.
Lighter fluid can be used instead of carbon tetrachloride.
Cleaning plasticized fabrics
Plasticized fabrics are impermeable to dirt, being com-
pletely dust-tight and proof agains-t oil and gasoline. A
dit-ty plastic surface can easily be cleaned by washing
with water and a synthetic detergent. Large oil stains,
etc., can be treated with white spirit, trichloroethylene
and similar solvents. Such organic solvents, however,
should not be used too frequently, as they tend to cause
stiffness in the plastic.
