Yesterday, as I loaded my car for a bimonthly trip to the transfer station, I came across this loose bottle, while placed in one of the large trash bins where we hold recycling in the garage, it was not in a bag for toting. As I lifted the bottle, I quickly noted the caked on detergent all around the cap and dripped onto the outside bottle. Tthe weight of the bottle told me that it clearly was not empty, and no attempt had been made to rinse it out. I set the bottle aside, delivered the trash and recycling.
I had already washed the laundry for the day, but knew I would have more for today. This morning found we wiping the gooey soap onto a towel awaiting laudering, and after pouring a 1/2 load measure of detergent into the washer, rinsing the rest of the detergent out of the bottle several times until the water ran clear, then placing the now clean, as is required by the transfer station, bottle to my awaiting, bag lined recycling bin in the kitchen.
A laundry loads worth of free detergent, and an expensive brand at that is today's freebie. I also find myself doing the same with what some consider to be "empty" bottles of shampoo, conditioner, body wash. DD and i tend to use up the hair products while the body wash gets some water added to the bottle before being placed at a sink for washing hands.
