Polyester. Fabric Specifics
To start our “research”, let’s clarify first what the specifics of this fabric are.
Polyester is an artificial fabric, however, except for synthetics, it is produced with the use of naturally occurring chemicals. Nevertheless, it still makes bleaching this sort of fabrics be under the question.
It is basically strong and colorfast but tends to catch and hold oily stains, besides, polyester items often turn yellowish when turning old.
This sort of material is often blended with natural fabrics like cotton, for instance, to give it more multitasking characteristics. When, for instance, it is joined with cotton, polyester becomes more resistant to wrinkling and tearing, its tendency for shrinking reduces and the fabric gains more strength.
Apparel made of this fabric is so popular because it has good water and wind resistance and it has great protective abilities from the environmental exposures.
On the other hand, polyester-made garments are flammable and tend to melt when set on fire or being exposed to the strong heat.
Of course, in household conditions, we are interested in how bleach affects polyester since it is often the only way to delete the stubborn blots.

How to bleach polyester fabric white? I need to deal with REALLY nasty stains and it seems that bleaching is the only option.

I have a dress that is made of cotton and polyester (almost 50\50 proportion). Now that it got badly stained, I suppose I will have to go for bleach, luckily, the dress is white! So the question is: how to bleach cotton polyester blend?
I would say the effect might be rather unexpected. You see, bleach works especially well on cotton, but polyester and other artificial materials deal with this stuff way worse.

I know quite a well-working remedy. You will need to take four cups of warm water and add two big spoons of white vinegar to them. This blend must be poured over the stain on the carpet and left for five minutes literally to soak it and work. After that, simply rub it either with a sponge or with a cloth. That has to work.
