Persil Ultra Pacs are designed to work in both regular top-loading washing machines and high-efficiency (HE) washers. Here's how to use them correctly.
For a regular top-loading washing machine
Start with an empty washer.
Place the Persil Ultra Pac(s) directly into the bottom of the wash drum.
Do not put the pac in the detergent dispenser.
Add your clothes on top of the pac(s).
Select the appropriate water temperature and wash cycle.
Start the washer.
How many pacs to use
1 pac: Small to medium loads
2 pacs: Large loads
3 pacs: Extra-large loads or heavily soiled clothing
Tips for best results
Handle the pacs with dry hands.
Store them in their original container with the lid tightly closed.
If possible, use warm or hot water for very heavily soiled laundry, although Persil Ultra Pacs are formulated to dissolve in cold water as well.
Don't overload the washer, as this can prevent the pac from dissolving completely.
If a pac doesn't dissolve
If you find residue on your clothes:
Reduce the size of the load.
Make sure the pac is placed in the bottom of the drum before adding clothes.
Check that your washer is filling properly with water.
Consider using a warmer water setting if your tap water is extremely cold.
Following these steps will help ensure the detergent dissolves completely and cleans your clothes effectively. #laundrydetergent
