Yes, it works well as a laundry detergent. Use a small amount—typically 1/8 to 1/4 cup per load depending on your machine type—and ensure you are not over-sudsing, especially in high-efficiency (HE) machines.

No, Sal Suds is free from synthetic dyes and fragrances. The scent comes entirely from natural Siberian fir and spruce essential oils.

Yes, the formula is biodegradable and made with plant-based surfactants, making it safe for septic systems and graywater setups when used as directed.
