Satin and chiffon are the two fabrics people most often ruin by treating them as one thing. They are not a fibre at all. Satin is a weave and chiffon is a weave, and what each one is made from changes the answer completely.

Satin and chiffon are weaves, not fibres
This is the point that unlocks everything else.
Satin describes a weave structure in which the warp threads float over several weft threads before passing under one. Those long floats sit on the surface, reflect light in one direction, and produce the shine. The reverse face has no floats, which is why satin is glossy on one side and matt on the other.
Chiffon describes a plain weave made from very fine, highly twisted yarns, loosely set. The twist gives it a slightly rough hand and a faint puckered texture, and the loose set gives it transparency and drape.
Either weave can be made from silk, polyester, nylon, or rayon. A polyester satin and a silk satin look similar and behave entirely differently in water.
So the first step is always to read the fibre content, not the fabric name.
Which fibre you have, and what it means
Silk is a protein fibre. It is weakened by enzyme detergent, by chlorine bleach, by heat, and by ultraviolet light. It water-spots readily.
Polyester is durable, unaffected by water, and holds oily stains stubbornly.
Rayon loses roughly half its strength when wet and shrinks dramatically with heat, which makes rayon chiffon the most fragile combination of all.
Nylon is strong but yellows under sunlight and is attacked by chlorine.
If the label is gone, treat it as silk, which is the most demanding of the four.
What goes wrong with satin
The long surface floats are the whole appeal and the whole weakness.
They snag easily, because a float is a length of thread lying exposed on the surface with nothing holding its middle. A rough nail, a zip, or a velcro strap will pull one out, and a pulled float on satin shows as a permanent line.
They also mark. A drop of water on silk satin leaves a ring, because water disturbs the way the floats lie and they do not settle back identically.
And they crush. Pressure flattens the floats, which changes how they reflect light, and a crushed patch reads as a dull mark even though the fabric is undamaged.
What goes wrong with chiffon
Chiffon fails differently. The yarns are fine and the weave is loose, so it distorts rather than snags.
Wet chiffon stretches under its own weight, and it stretches unevenly because the weave is open. Hang a wet chiffon garment and it comes out longer and misshapen.
It also frays readily at any cut edge and it slips against itself, which is why chiffon seams pull apart under strain.
Washing satin and chiffon
Hand washing is the safe route for both, and it is quick because there is so little fabric.
Cool water. Never warm, never hot.
A small amount of gentle, non-enzyme detergent, dissolved in the water before the garment goes in. Never pour detergent directly onto satin, which spots it.
Submerge and move it gently through the water for a minute. No rubbing, no scrubbing, no wringing.
Rinse in clean cool water at the same temperature.
Press the water out between two towels rather than wringing, which crushes satin floats and distorts chiffon permanently.
For machine washing, only where the label allows it: a fine mesh bag, cold water, delicate cycle, lowest spin, and nothing else in the drum with hardware.
Drying
Never a dryer for either.
Dry chiffon flat, reshaped to its original dimensions, since it holds whatever shape it dries in and hanging stretches it.
Satin can be hung on a padded hanger if the garment is light, or dried flat if it is not. Avoid pegs, which crush the floats where they grip.
Keep both out of direct sun, which fades dye and degrades silk and nylon.
Pressing
From the reverse side, always, on the lowest heat that does anything.
Use a pressing cloth. A hot iron directly on satin glazes the floats and creates a shine that does not come out.
Steam held away from the fabric is safer than contact pressing, and on chiffon it usually does the job on its own.
Never press satin while damp if it is silk, since water plus heat is what sets a water mark permanently.
Stains
Blot immediately and never rub.
Test any treatment on an inside seam, since both weaves show treatment marks readily.
On silk, avoid enzyme detergent and chlorine bleach entirely.
For a water spot on silk satin, the counterintuitive fix is to dampen the whole panel evenly and let it dry flat, so there is no boundary between wet and dry areas to leave a ring.
The Charlotte part
Humidity is the local factor and it works on both fabrics in ways that are easy to miss.
Carolina summers are genuinely humid, and both silk and rayon absorb a great deal of atmospheric moisture. A silk satin dress hanging in a closet through a humid stretch is holding real water, and damp protein fibre is where mildew starts. Mildew stains silk permanently rather than washing out, so anything worn should be aired properly before it goes back in the closet rather than hung straight away.
Humidity also slows the flat-drying step considerably, and a chiffon garment lying flat in a damp room can take a full day. The answer is airflow rather than heat, since heat is the thing that damages both fabrics. A fan on a drying rack is the safe way to speed it up.
The long formal and event season here is the third factor, and it argues for spot cleaning between wears rather than washing after every one. Every immersion is a risk to a satin surface, and most of what needs cleaning on an occasion garment is at the underarm and hem rather than across the whole piece.
Where the rest of the outfit goes
These fabrics stay out of a machine, and the linings, underlayers, and everything worn with them do not, and those are the pieces actually holding the body oil.
The machines at our self-service laundry on The Plaza let you run a genuinely gentle cycle with a low spin as a separate choice, and give the heavy loads their own drum where nothing fine can snag.
Our machines and the store are cleaned daily.
Nou wash-dry-fold service covers the everyday laundry.

The short version
Satin and chiffon are weaves rather than fibres, so read the fibre content before deciding anything, since silk, polyester, and rayon versions behave completely differently. Satin’s long surface floats snag, crush, and water-spot, while chiffon distorts and stretches because its weave is fine and loose. Hand wash both in cool water with a gentle non-enzyme detergent, never wring, and press the water out between towels. Dry chiffon flat and reshaped, never hung. Press from the reverse on low with a cloth, since a hot iron glazes satin permanently.
