I had tried the stair remover on my washer seal for it to only minimally budge the black stains. The laundry sheets I do love them and have no complaints aside from the price point. Same with the dryer sheets. Both the soap sheets and the dryer sheets have a great smell to them and are great for removing stains and freshening laundry.

worked immediately for me. fixed the smell and also showed a massive difference in the dryer! the trap was twice a full as before.

works great. Amazing when you clean your lint trap for the first time using the whole system. it's amazing.
