Potty training accident. DS2 had all day in which he could have pooed all over the wooden floor downstairs, but he chose to do in the thirty seconds or so it takes to get up the (carpeted) stairs and landing to the bathroom.
TMI but it was really squishy and impossible to get up cleanly. I've tried treating it with Troubleshooter 101 but this morning I just have a huge stain.
Any ideas? It's a wool, flat-ish pile carpet so am a bit worried about colour-fastness. TIA.
