Description

Starke Hydrate Waterless Wash Concentrate is the concentrate form of Hydrate Waterless Wash—same dirt-encapsulating formula for gelcoat, paint, metal, and plastic, mixed to RTU when you want bulk economy for the wash bay.

About 3/4 oz of concentrate yields 16 oz of RTU. Dilute into a clean labeled bottle for dock touch-ups and shops that burn through waterless wash faster than single RTU bottles.

Why detailers keep it on the cart

  • Concentrate for Hydrate waterless wash—mix as needed
  • ~3/4 oz concentrate makes 16 oz ready-to-use
  • Same gelcoat / paint / metal / plastic use as RTU Hydrate
  • SKU: HYDC16, HYDC128

How to use

  1. Measure concentrate into a clean bottle; top with water to the RTU ratio on the label
  2. Shake; mist a cool panel or dampen a microfiber; wipe in straight passes
  3. Finish with a dry towel face; store concentrate sealed and labeled

Note: Mix only what you will use; keep concentrate labeled and away from unmarked bottles. Same light-soil limits as RTU—wet-wash heavy salt and grit first.
