Does the "Do not use chlorine based bleach" warning have to be strictly followed?

If it is a colored item I would follow the restriction.

If you don’t care what happens to the item, you can experiment, but it will probably reduce it’s lifespan.

Best to side with caution.

Yes obey it. Two reasons:

- depending on the dyes used in the fabric, it can wipe them out or cause them to become splotchy

- more importantly, some of the fabrics will react chemically to the chlorine and cause it to fall apart because of the sodium hypochlorite in the bleach.

But it’s your choice to ignore the reasoning. Sounds like you have already made up your mind.

So you believe the label to be a hoax?

Nah. Bleach the hell out of what ever it is.

It is like “Don’t wash Wool in hot water and put in a dryer on High Heat” your large size sweater will fit a 4 years old

@rebbel, @YARNLADY, @elbanditoroso, @kritiper It’s just for the first time washing, and the thinking is to use more water that what we use for no need to worry kind of clothes.
I’m trying to think where I got it from about wash with small amount of bleach even new clothes since you don’t know what’s on it (people tying it on stepping on it by accident etc.)

@stanleybmanly I posted an OP re. fast food addiction claims as an a example so it doesn’t have to be a hoax, just about going overboard to avoid legal claims.

Well, you can’t really skip the first wash of cloths (new or otherwise).
Just don’t use the chlorine.

…the chlorine based bleach. Alright.

…based bleach.
You are correct.

@rebbel Thanks.

It’s on a 100% polyester. Is there anything more nothing to worry about kind of material?

Chlorine bleach is generally NOT recommended for polyester. It doesn’t react well with the fibers for removing colors, and can degrade the fabric, especially the threads holding the item together.

@YARNLADY I didn’t claim it is recommended that you use chlorine based bleached for polyester, just that in my experience there was never any special instruction whenever it’s polyester or mostly polyester.

I don’t understand this article “https://www.leaf.tv/articles/what-fabrics-are-most-commonly-used-to-make-clothing/ I find it’s a combination of rayon plus polyester plus I can’t think of the 3rd and 4 the ones not the materials that need high maintenance.

White cotton materials, like socks, sheets, tshirts and such, can be bleached. It shortens the life of the item but until then they are really super clean and white and smell good until then.
I would not use bleach any non-white, non cotton item such as polyester. It would just burn holes right through it.
