Product review (3 stars): Moldy smell problems
I have the LG front loader and I do like it now. At first I have had issues with that moldy smell. I did pick up the smelly washer product of Paul Flynn and wasn't really impressed with it. What seems to be working really well is this Oxi-Clean powder stain remover. I add it with the detergent and it's been working really well. I have not had any more moldy smells at all. Another thing I noticed is I used to use an unscented for sensitive skin detergent because my husband has sensitive skin, and I think that may have also contributed to the problem. I'm not 100% sure on that, but since I switched back to a scented line it's not an issue anymore. The 2 together Oxi-clean and a scented detergent has been working great for me.  I also keep the door open when it's not in use.
