I have bought some older hand embroidered pillowcases. Some have the age yellow like from body oils I suppose. How do I safely get the yellow out without ruining the embroidery work?

Oxyclean works for me. I did an old quilt my DDIL inherited from her GM, with hand embroidery on it. It came out beautifully, even took some stains out, just use a gentle cycle.

I have never been able to get it out. I am interested in what others have to say.

Soak in all fabric bleach (non-chlorine) - for 2 to 3 days.

Non chlorine bleach will not eat the fabric like the bleach will?

YEP.... I use only POWDERED oxyclean.. the spray stuff doesn't works as well to me... and I let it soak minium of over night..... if not several days

There is also a product I order off Ebay called
Linen Wash..a fine specialty cleanser.
Has worked really well.

Oxyclean works for me too.

Ok I will give Oxyclean a try on one of the less important ones first. Thanks.

I would use RetroClean: http://www.retroclean.com
