Many thanks to the NewLeaf line of organic cleaning products, whose sponsorship of ZRecs over the last month has helped pay the blogging bills. We encourage you to check out their astonishingly straightforward and exceptionally non-toxic products -- you'll probably know what every ingredient is, and if you're like us, you'll appreciate the company's commitment to transparency. We had much more to say about the company back in March.

We're also pleased to report that NewLeaf has agreed to give away a second set of NewLeaf cleaners to a ZRecs reader (a bottle each of NewLeaf's All Purpose Cleaner, Glass Cleaner, Bathroom Cleaner, and Organic Dish & Hand Soap). If you didn't win the giveaway we launched this sponsorship with in March, here's a chance at redemption! We're looking for the answer to this question: Of chemicals commonly found in homes, how many have been linked to allergies, birth defects, cancer, and psychological abnormalities, according to the Consumer Product Safety Commission? (Hint: This answer is also on NewLeaf's website. We aren't telling you the page this time.)

Email your answer to editors (at) zrecs (dot) com with "NewLeaf" in the subject line, plus your answer to the trivia question and your U.S. mailing address in the body. We'll accept entries until Thursday, April 14 at 1:00 p.m. CT and select a winner from all correct entries, and the winner will get a free $24 set of non-toxic household cleaners shipped to their home.

Good luck!
