I always forget about this free Nikwax sandal wash offer. It’s probably because you have to take a 5-question quiz after signing up and I hate quizes. They were easily the worst part of school. The threat of a pop quiz always put a timer on my harrowing escapes from inside the gym lockers. I think it’s why I get panic attacks just from smelling Gold Bond.
Seriously though, you have to take a freaking quiz and answer all the questions correctly. Click the “clue” button next to each question and it will take you to the page where the answer is found. It took me about 4 or 5 minutes total.
