Many of these stains cannot be easily identified and require the fastest and
most efficient of
removal without damaging the fabric.
If a stain is identified as dry
side or protein, it is no problem
since we can go to the proper
method of removal.
Some other stains are vague
and may have a combination of
dry side, tannin and protein.
For example, chocolate is dry side, tannin and protein and coffee may also be
It is important to know the proper order of stain removal to deal with the
Working the unidentified stains in the wrong order can very easily set the
On a tannin stain, not properly identifying it and working it with a protein
formula will cause
the stain to become set.
The manufacturers have the proper chemical technology making unidentified stain
easy and fast.
Milt and Edie’s Drycleaners in Burbank, CA, is one of the busiest drycleaners in the nation.
They handle high quality items and boast that they give a two-hour service at
request. It is important that the stain removal method used is safe and fast.
The following method was most successful and devised in my most recent training
Flush. This is an important step and not wasted. A cloth is held under the
fabric and poor dyes
can be noticed.
On my visit, a $3,500 Robert Mouret dress was received for spotting and
On the initial flushing action,
poor dye on the dress was
noticed without damage to the
dress. The customer was
notified of the poor dyes and
was able to bring it back to the
Neutral lubricant. The
process of using neutral
lubricant is safer than a protein
or tannin formula.
Protein and tannin formulas
initially used can set some
stains and dyes. It is important
that the neutral lubricant be
mixed properly to avoid
excessive suds. This makes
Mechanical action. This
includes tamping and brushing.
The white brush is for wet side
spotting and the black brush
for dry side spotting.
For delicate fabrics, a cloth
should be put on the brush or
use a silk brush. When
brushing delicate fabrics, the
brush should be angled so only
the sides of the brush contact
Flush. Flush the fabric
thoroughly into a cloth to make
sure the lubricant is removed.
Tannin formulas. This
formulation will not set protein
stains. A protein formulation
used initially will set tannin stains.
Avoid using strong acids and acetic acid. Acetic acid used on some fabrics can
Acetic acid also has an unpleasant odor which is difficult to flush and can
affect some acetate
At this point we have worked the identified stains for tannin.
Protein formula. This is used for the protein portion of the unidentified stain.
manufacturers make a low pH protein formula which is relatively safe to silk and
Avoid the use of ammonia and ammonia-based products. This will cause color loss
wools and some dyes on other fabrics.
At this point we have worked the stains for tannin and protein. The next step is
to work it for
dry side using wet side detergents.
Nonionic detergent. This detergent helps to remove dry side staining such as oil
and grease. It
is effective on many stains with an oil content which includes ink, mustard,
sauces, etc. It is not
effective on paint, nail polish, glue, etc.
Hydrogen peroxide. This should be used at a 3% concentration.
If a difficult dry side stain is noticed after the wet side process, it must be
dried and pre-
spotted on the dry side.
Oily-type paint remover.
Oily type paint remover and amyl acetate.
Expanded bleaching process for effective and fast stain removal
The last traces of staining require an effective bleaching process. At Milt and
Drycleaners, we transferred the liquid bleaches into gel form. This gives a more
safer application. This includes sodium hypochlorite and hydrogen peroxide.
We set up a gradual and more concentrated hydrogen peroxide mixtures.
The following strength of hydrogen peroxide can be effectively used.
Hydrogen peroxide: 3% 10 volume.
Hydrogen peroxide: 6% 20 volume. This must be tested.
Hydrogen peroxide: 9% 30 volume. This must be tested.
The 3% and 6% can be accelerated by ammonia or protein formula but must be
