Choosing a proper detergent and or softener can be tricky. Here is what we advise from 42-year textile veteran, Jud Lusk.
A nonionic surfactant with good emulsifying properties should be a part of the detergent system. Nonionic surfactants wet and clean fibers more readily than other classes of surfactants and are compatible with other products in the wash. They remove and suspend soil while having some anti-microbial properties. The use of sufficient detergent for the removal of soils, especially oils and fats, is essential to prevent re-depositing of soil and irreversible graying or dulling of the sheets. Many commercial laundries use what is referred to as a “built” detergent which means they contain additives such as alkali to adjust pH to 8-9 for maximum cleaning.
Softeners provide smooth and supple fabric and a fresh scent. A softener should be chosen that is readily removed in subsequent laundering to avoid build-up and consequent soiling, water repellency, or greasiness.
Most importantly, follow your washing machine instruction guide for directions on powder vs liquid. And always look for non-chlorine bleach options.
