Welcome to a 2-part NOT.
Tonight’s part is things you discovered this year that you’d definitely recommend for others or will keep using/doing/etc for yourself.
I’ll start – I’ve been trying to identify where I could reduce single use plastic waste. So one of the places I looked at was household supplies. I got a box of earthbreeze laundry detergent sheets from the crunchy grocery store and they worked really well! I would add if you have any space issues, mobility issues, or arthritis issues, wow so much easier to use those than fuss with a giant bottle of laundry detergent. Definitely more expensive than the Target brand soap I had been using, but since I am only doing laundry for one person, that wasn’t that big a deal.
Later in the year I started ordering some cleaning supplies from Blueland. You absolutely don’t need their special foaming hand soap bottles, I just have been using empty ones from Bath & Body Works. It’s nice that I’ve got like 5 bottles’ worth of hand soap under the sink, but taking up less space than a bottle of dish soap. Price of these ends up being cheaper than say buying soap at Bath and Body Works or single bottles at the store, not as cheap as buying the giant refill bottle of SoftSoap or whatever at Target.
I used up the detergent sheets from earthbreeze, so I switched to the Blueland laundry detergent tablets about a month ago. Still working great and takes up almost no space to store. I’ll be trying out their dishwasher tablets in about 2 weeks when I finally finish off the giant box of Costco brand dishwasher pods. These Blueland tablets are significantly more expensive than the Costco brand, but I don’t run the dishwasher every day so worth trying them out. Worst case scenario I just go back to Costco if they don’t work well.
I know I’ve mentioned before that I have a small house, and the convenience of having such small storage impact is also fantastic for these. The Container Store sells some of the Blueland stuff as well, which was how I tried out the hand soap.
