Winsol Crystal Clear 550 – Heavy-Duty Glass Restoration for Hard Water & Etching

Winsol Crystal Clear 550 is a powerful glass treatment designed to restore clarity to glass surfaces that won't come clean with routine washing or extra effort. Perfect for glass with haze, etching, or stubborn buildup caused by hard water, pollutants, and runoff from cement, this product is an essential solution for window restoration.

Key Features:

• Restores Glass Clarity: Effectively removes stage 1 alkaline buildup, exhaust particles, chemical deposits, and water spots.
• Tackles Hard Water & Etching: Removes haze and etching caused by hard water, pollutants, and cement runoff.
• Restores Surface Integrity: Reduces minute pitting and hard water buildup, leaving glass surfaces clear and smooth.
• Coverage: One gallon restores between 1,200 to 4,000 square feet of glass, making it ideal for large jobs.
• Safe for Indoor & Outdoor Use: Works both indoors and outdoors to rejuvenate glass surfaces without damaging them.

Important Considerations:

• Contains Harsh Acids: Crystal Clear 550 includes hydrochloric and hydrofluoric acids. Always wear gloves, protective clothing, boots, and splash goggles during application.
• Test Glass First: Always test a small area before full application to prevent damaging the glass, especially on hot days or in areas with potential coating or stage II corrosion.
• Stage II Corrosion: If your glass has stage II corrosion (white or hazy appearance), Crystal Clear 550 will not correct it and may visually expose existing corrosion. In such cases, glass replacement may be necessary.
• Mixing & Application: Ready-to-use or dilute by 50% with cool water. Apply with a natural sponge or clean cloth, and rinse thoroughly with water or trisodium phosphate solution.

Safety and Handling:

• Not a Cleaner: Crystal Clear 550 is a glass restoration product, not a cleaner. Clean glass before use.
• Avoid Non-Glass Surfaces: Do not apply to window frames, non-glass surfaces, or self-cleaning glass (Titanium glass).
• Quick Action Required: Work quickly and avoid excessive use to prevent runoff that may damage surrounding areas.

Note: Before use, review the Authorization and Waiver for use with building managers and owners (available in the Documents tab).

READ INSTRUCTIONS BEFORE USE :
USE STRAIGHT OR DILUTED BY 50% WITH COOL WATER. ALWAYS WEAR RUBBER GLOVES, PROTECTIVE CLOTHING, BOOTS AND SPLASH GOGGLES. AVOID CONTACT WITH SKIN.
Always use plastic pails and containers. Do not use metal or painted containers.  
Clean window glass before using CRYSTAL CLEAR-550. CRYSTAL CLEAR-550 is NOT a cleaner. 
ALWAYS TEST GLASS BEFORE APPLYING CRYSTAL CLEAR-550 TO ENTIRE WINDOW.
Check for surface coatings and residues such as silicone treatment, building sealer and waxes. (According to some glass manufacturers, silicone treatments and building sealers may be removed by applying toluene first to soften the film and a low abrasive rubbing compound to remove the residue.)
CHECK BOTH SIDES OF GLASS FOR STAGE II CORROSION. (GLASS WILL USUALLY TURN WHITE WITH COATINGS AND STAGE II CORROSION WHEN TESTED.) STAGE II CORROSION IS NOT CORRECTABLE AND GLASS SHOULD BE REPLACED.
Apply CRYSTAL CLEAR-550 with a natural sponge or a clean, white cloth. Wring sponge or cloth to prevent runoff. Keep solution from running down any building or other surfaces. If product runs down the glass, it is being overused. Apply for one to two minutes, then rinse with water or a dilute solution of trisodium phosphate. Repeat as necessary.
DO NOT USE CRYSTAL CLEAR-550 ON WINDOW FRAMES OR ANY NON-GLASS SURFACE. DO NOT USE ON SELF-CLEANING (TITANIUM) GLASS.  RINSE AWAY ANY SPILLS IMMEDIATELY.
NOTE: If glass becomes hazed or white, proceed no further until you can determine if it is a coating, building sealer or Stage II corrosion, or if given permission by supervision or building management personnel. 
CAUTION:
Contains Acid: CAS 7664-39-3.  Do not take internally. Do not rub in with fingers or permit contact with skin or eyes. Always wash hands and contaminated skin after using, paying particular attention to skin under nails. Avoid breathing vapors.
