Bleach toilet cleaner spashed on white carpet and make yellow spots.

I don't think you will be able to dye the colour back to white. Suggest you use Toilet mat in front of toilet. Or, you could use waterproof Pens (Sharpie??) to make Flowers from your Spots.

Is this an around the toilet rug?, If so, spray the spots with a stain cleaner, ex. Spray N Wash. Let sit 1 hr, and wash in a pail of cold water, ring out. Use the pail again, and put a mixture of vinegar 1/4 cup to gallon of cold water, let soak 1 hr. This should bring the yellow spots out of the carpet. If not soak in hydrogen peroxide same mixture. 1/4 cup to a gallon of water. Rinse and hang to dry. When it dries look at it in natural light. (Bring it to a window) and look to see if the spots are gone, if not, see if you could have it dry cleaned. Good Luck!

I'm afraid I don't know, but they do many colours..... Good luck!
