Go ahead ... think I'm silly! But, I think we should all start sharing products that make our life easier!
Here's mine ... and I plan on sharing others, too. Sprayway glass cleaner. It's available at Target (and lots of other stores), but right now, it's got a pink cap on it. It's awesome. When I worked for Enterprise Rent-A-Car, it was the only thing we used. For a few years, I wasn't able to find it at regular stores, so when I finally found it, I was so happy. It stays where you spray it and wipes off without leaving a streak or film.
What's your favorite product? Cleaning or otherwise.
