Alien Power 72 Fl Oz Instant Stain Remover Spray for Mold and Mildew and Grout, All Purpose No-Scrub Cleaner for Bathroom & Household Surfaces, Tiles, Wall, Black Mold & Washing Machines - 3 Pack Set
ALIEN TAPE

Alien Power 72 Fl Oz Instant Stain Remover Spray for Mold and Mildew and Grout, All Purpose No-Scrub Cleaner for Bathroom & Household Surfaces, Tiles, Wall, Black Mold & Washing Machines - 3 Pack Set

Key Highlights
  • Gentle and convenient maintenance.
  • Versatile on many surfaces.
  • Time-saving cleaning solution.
Main Highlights
  • NO-SCRUB FORMULA — SPRAY, WAIT, AND WIPE AWAY TOUGH SURFACE STAINS: Alien Power's concentrated formula is designed to penetrate deep into grout lines, caulking, porous tile, and textured surfaces to lift stubborn discoloration at the source — not just mask it. Spray directly on the stained area, allow a few minutes of dwell time, and wipe clean. No scrubbing brushes, no repetitive effort required for most surface stains.
  • ONE CONCENTRATE KIT MAKES 24 OZ OF READY-TO-USE CLEANING SOLUTION: Each order includes three 1 oz concentrate packets and a reusable 24 oz spray bottle — just add water and shake. A single packet makes 24 oz of solution, giving you significantly more value per dollar than pre-diluted sprays sitting on a store shelf. The concentrate format stays potent longer before mixing and ships more efficiently than heavy pre-filled bottles.
  • TACKLES THE STAINS THAT STANDARD CLEANERS LEAVE BEHIND: Alien Power is formulated for stubborn surface discoloration that everyday household sprays struggle to address — including black mold stains, dark grout staining, hard water deposits, soot residue, yellowing buildup from nicotine, and heavy organic staining on tile and tubs. The concentrated formula is engineered to break down the structure of tough stains on contact.
  • MADE IN THE USA — CONCENTRATED FORMULA, NOT A WATERED-DOWN SHELF SPRAY: Alien Power is manufactured in the United States and sold as a concentrate — not a diluted ready-to-use spray padded with water before it reaches you. Most store-bought surface cleaners are heavily diluted before packaging. Alien Power's concentrate lets you mix only what you need, store the rest, and get more active cleaning formula per dollar spent.
  • EFFECTIVE ON EXTERIOR SURFACES — SIDING, GUTTERS, BOATS, AND RVs: Heavy organic staining and dark streaking on vinyl siding, gutters, boat hulls, and RV exteriors requires a stronger-than-household formula. Alien Power's concentrate handles exterior surface discoloration where moisture and outdoor buildup combine, without requiring pressure washing equipment. Spray on, allow dwell time, rinse off.
  • POWERFUL FORMULA — FOLLOW LABEL DIRECTIONS FOR BEST RESULTS- Alien Power is a professional-strength concentrated stain remover built for tough jobs that everyday sprays can't handle. For best results, use in a well-ventilated area and follow all label instructions before and during application. Mix only what you need, store the remaining concentrate in a cool dry place, and keep out of reach of children. This is a targeted stain removal solution — not a general-purpose daily surface wipe-down spray.
