When we had a live-in maid, she would help the girls scrub their school bags with detergent and then sun the bags for days. Now that we are without a live-in maid, the girls and I have to do this chore ourselves. Thanks to Pre Spot laundry stain remover from Melaleuca, we can now spot clean the school bags with just a few sprays. For stubborn black stains, I use concentrated Sol-U-Mel from Melaleuca and scrub the surface with a piece of wet tissue. Once thoroughly cleaned with Pre Spot, I spray some Sol-U-Guard disinfectant from Melaleuca onto the bags interior and exterior. I bet their bags were teeming with germs as the girls place their bags everywhere on the floor and even on the road.
