  • Brush Kits Built for Taylor® Machines — Every brush needed to reach every tube, passage, and pocket.
  • Machine-Safe Lubricant — Food-grade, designed for soft-serve machines, and won’t damage seals.
  • Proper Sanitizer (No Guessing) — Compatible with soft-serve systems; dissolves easily and rinses clean.
  • Operator-Proven — The exact supplies we use in our rebuild shop.
  • Fewer Service Calls — The right cleaning and lubrication prevent wear on parts.
  • Same-Day Shipping — Order by 3 PM ET and it ships today.
  • If we don’t use it in our shop, we don’t sell it.
