The soap stick is simple and it works so well! This product is so effective it's been known to save full loads of toddler laundry and get mildew out of shower curtains.
Typical stain remover comes in plastic, often non-recyclable packaging. In liquid form, you are paying for a high percentage of water, not just the product. Mix it up and remove your laundry stains with the soap stick!
Simply wet the fabric and rub the soap stick onto the stained area, then wash as usual.
