The stinkies have quite suddenly returned with a vengance. Ammonia burn, during daytime, not naptime.
I think I'll take the quick and easy route this time, and follow the manufacturer's advice. Wash them with bleach! (Just the inserts, that is.)
So, since I don't trust my front load washer to distribute bleach without causing trouble, my plan is to put a 1/4 cup of bleach in a 5 gallon bucket, fill it with water, and let the (clean) inserts soak. Then I'll run them through the washing machine to get the bleach out.
I'm really wishing right now that I had our old top load washing machine (still sitting in the basement) hooked up so I could just soak and wash them in there. But, alas, that requires some extra plumbing work that I'm leaving up to my husband's ingenuity to figure out. In all his spare time, you know?
Hopefully a bleach wash for the inserts will put us back to a starting point of happy bottoms.
