The Wheeky Pets Laundry Helper is a great way to keep your washer free of pet hair and debris, and prevent plumbing clogs. It loosens and contains all pet hair inside the bag, which you simply shake out after washing and before drying. The Wheeky Pets Laundry Helper will save you time and money. It does, however, require you to do things a little differently than you may be used to. For best results, follow these 4 simple steps: 1) SHAKE: Take pet laundry outside, and shake out any loose hair. 2) WASH: Put pet laundry into Wheeky Pets Laundry Helper. Please make sure the bag is no more than half full. There must be room for the laundry to move around inside the bag and get clean. Pour unscented laundry detergent directly into the bag (on top of the laundry) and zip closed. Evenly distribute laundry within the bag to ensure a balanced load. Wash as directed. 3) SHAKE AGAIN: When wash cycle is done, take wet bag and laundry outside, remove pet laundry from the bag, and vigorously shake out loose pet hair and debris. Then, turn wet Wheeky Pets Laundry Helper inside out and also shake vigorously outside to remove debris. Hang bag to dry. Do not put bag in dryer. 4) DRY: After shaking, put wet pet laundry in dryer and dry as directed. Do not put laundry bag in dryer – please hang dry. Remove any hair/debris from dryer lint trap. If you have a lot of pet laundry or bedding, you may want to consider purchasing two Laundry Helpers, as two half-full bags will help to balance the washing machine load.
