Bleach accident
 

I have a king sz sheet to use for backing & it got splashed with bleach before putting in the washer. It did get washed but
there are sploches without color. Would bleaching take out the rest of the color? or would Rit color remover work better?
I should know this but am drawing a blank. Can anyone help?

I doubt washing the sheet with bleach will remove all the color unless you use a ton of it. Using a lot of bleach will weaken the fabric, it's very caustic. Depending on how many bleached out spots there are and how big they are perhaps you could appliqué something over them. I have no clue about Rit color remover but anything that can totally remove color has to be pretty harsh.

why not splash some bleach around the sheet so it becomes a pattern and use it that way

I think this is what I would do. Better safe than sorry.

I think re-washing with bleach will not bleach out the color uniformly but end up with a splotched look. then again, the splotched look might work.

Won't help you now but maybe in the future. I always keep a bottle of hydrogen peroxide next to the bleach. Hydrogen peroxide will stop the bleach action It won't prevent the initial action but will prevent the bleach from bleaching more.

I agree with others. Buy a new sheet.Cut down and use the bleached one for something else. Pillow cases perhaps?

I realize that you didn't say 'mix' bleach and hydrogen peroxide, but I don't even like keeping them together on the shelf.
This is Very risky! Mixing bleach and hydrogen peroxide creates a toxic gas that is extremely dangerous to lungs and eyes.

It can cause an explosion under the right circumstances.

Just my old lady caution coming out....

Yikes, I'm actually glad you said so - not that I use them in tandem, but I sure wouldn't want to make that mistake!
