FAQ.
Short answers. If we don't know, we say so.
The product
Does one sheet really equal one full load?
Yes. Every sheet is weighed to a full-load surfactant dose (4.2 g). For extra-large or heavily soiled loads, use two.
Does it work in cold water?
Yes. Sheets dissolve fully in cold, warm, and hot. Any temperature, any cycle.
HE compatible?
Yes. Low-suds formula built for HE, top-load, and every washer built this century.
Does it contain PVA?
No. There is no PVA or PVOH — the sheet is built on corn fiber, and every ingredient is printed on the label.
What about sensitive skin?
Every ingredient is named on the label: no SLS, no SLES, no dyes, no optical brighteners. The fresh linen scent comes from plant and essential oils, not a hidden fragrance blend. We can't make medical claims, so if anyone in your home has a diagnosed skin condition, check the list with your doctor first.
