I bought a love seat and chair with off white cotton covers. The tags on the coves said that they were washable, but when I washed them (using cold water and Tide) they came out with bright white splotches on them. Can I dye them a darker color without having the light spots show through?
It sounds like you have some fabric that is unstable or perhaps you used Tide with bleach? I don’t know what happened, but I think I would take these back. If they say machine-washable, they should be washable without incident. I wouldn’t try to re-dye them.
