For Wade-Fite staining, what is the recommended remedy if tap water was used during staining?

Water purity during Wade-Fite staining is important because minerals and impurities in tap water can interact with the stain, cause precipitation, or leave background artifacts that obscure acid-fast organisms. If tap water was used during staining, the recommended remedy is to switch to distilled water for all rinsing and washing steps (and, if needed, repeat the staining with distilled water) to prevent these artifacts and restore proper staining and contrast. Using more tap water would worsen the artifacts, and simply changing the stain time or adding fixative won’t remove mineral interference.
