A:
Yes. I have anyway. I have a Samsung washing machine that has the “Affresh” cleaning cycle on it and even tho the box says to use one, I double up purely because I’m super ocd about my washer being as clean as possible. If one is good, two must be better, right? Lol. That’s my logic. To answer your question though, mine was fine with two tablets and nothing bad happened to my washing machine by using two.
