I give up!
I give up!  I have relative hard water, and I read a lot of reviews warning about it.  I try everything to make it work but I couldn't.  A less than 4  stars review on this product would be unfair for MWFSS but I can't give a 5 star review.  The best results I got was using a boar brush.  About the smell I really like it.  Is in the neighborhood of TOBS's Mr.Taylor's. Hope it works for you!
