1. Woolite Oxy Deep carpet cleaner -- The best spot cleaner for carpet I've found. Not only does it take care of the spit-up like a charm, it took out some older stains of unknown origin that I had tried unsuccessfully to remove with a different brand.
2. Kirkland household wipes -- This is a Costco product and comes in a three pack. Every time they are on sale I stock up. They are great for sanitizing door knobs, bathrooms and kitchens, but also for cleaning toys, the exersaucer, and the changing table following a particularly ill-timed diaper change...
3. OxiClean laundry spot remover -- The overenthusiastic Ron Popeil wanna-be who hawks this stuff on TV isn't exaggerating. It gets everything out. I keep a bottle upstairs to spray the worst stains as soon as I can. And I keep another bottle downstairs in the laundry room to catch anything I missed. It all comes out clean as a whistle.
And after a long day with triplets that requires the use of these three products, I recommend this:
And remember, if it doesn't work the first time you can always reapply!
