This is a last resort stain remover. I did it and had great results but it contains bleach and could ruin coloring. However, I had water damage from A/C leaking on my carpet. Until the unit was replaced we had stinky water stained carpet that was beginning to mildew (pink and black).
I personally don't want to breathe in mildew, and we had to wait two weeks before we could get carpet. Desperate times call for desperate measures, but it worked so good, I just had to share it.
I did have tan colored carpeting and it actually looked cleaner and fluffier than it was before water damage, no fading or discoloration.
spray bottle with 1/4 bleach
steaming hot pitcher of water
several white towels
Saturate solution into padding. Use a stiff brush to scrub solution into carpet fibers.
Let sit 30 min-1 hour.
*If smell is too strong, dilute with the hot water, and open some windows.
Rinse with steaming hot water. Blot dry with white towels, get as dry as possible.
Use carpet shampooer or steam vac with shampoo or vinegar to neutralize smell. Mixing chemicals can be deadly, including vinegar and bleach. Vinegar does an amazing job of getting rid of the smell of bleach. The bleach must be rinsed first!!!!
