Stain removal

Zote comes in a box of flakes now. Saw it at Walmart.
Also, my kid works at a restaurant and wears white long sleeved shirts. They get filthy, especially the cuffs. I sprayed them and washed twice. Still dirty and stained. So I poured CLOROX ULTIMATE CARE BLEACH on the cuffs followed by BORAX. Using gloves and a mask I did a little hand scrub and watched the stains disappear. Washed as usual. Voila
