Wetcleaning silk and rayon wedding gowns requires more expertise and skill due
inherent fiber sensitivity and weave limitations.

For example, some silks may require softening agents while others may need more
hand, requiring stiffening agents.
Before wetcleaning it is important to pre-spot all stains and soil due to the
fragile nature of the
fabric that can only receive minimum mechanical action.
I try to stay away from anionic detergents to avoid a counter action with
that are used for wetcleaning silk. We use nonionic detergents and other
formulations that do
not react with these detergents.
Some of the pre-spotting agents that we use have a hydrogen peroxide base which
for oxidized stains. The important thing about the pre-spotters is that they
must be left on the
fabric for a period of time to loosen the staining prior to wetcleaning. It
should be left on at least
one hour, which gives it time to loosen the soil and staining.
The best detergent to use is a cationic detergent which has enzymes and a
slightly acid base.
It softens the silk, giving it luster and inhibits shrinking.
The gown should be soaked at least 15 minutes in 100°F temperature and drained. It should
then be put in a rinse tank with a softening agent. It is then hung and possibly
hosed off to
remove residual residue. Remember the water temperatures in wetcleaning, rinsing
bleaching should be the same to avoid thermal shock to the fabric.

The gown is then rinsed with a softening agent and hung. A reducing bleach that
acts as a
whitening agent is sodium hydrosulphite.
Use two ounces of sodium hydrosulphite per gallon of water at 100°F.
Nonionic detergents are also used for penetration and softening of the fabric.

The rayon fabrics are pre-spotted. Alkali, however can be added to pre-spotters
for better soil
and stain removal.
The wetcleaning process used for rayon is similar to the processes we use for
silk. After the
silks are rinsed and softening agents are added and then hung, weights are
clipped on to the
hemline to alleviate the chance of shrinkage. If the weights are properly
applied, the possibility
of shrinkage will be eliminated. Rayon stretches while in a wet condition but

The best bleach for rayon is sodium perborate or sodium percarbonate. Sodium
is usually chosen because of its ability to dissolve in cooler water.
Add two or three ounces per gallon of water at 100°F temperature. Add a nonionic detergent
to maintain softness. Soak for two to three hours, rinse and use an acetic acid
bath to neutralize
the alkali in the bleach. Rinse, using a softening agent and hang.
As we previously mentioned, use weights to correct any shrinkage.
