Soft99 Glaco Glass Compound Roll On Glass Cleaner 100ml

Perfectly Prepare Glass Surfaces — The Soft99 Glaco Glass Compound Roll On as the Foundation for Every Glass Sealant

What makes the Glaco Glass Compound Roll On special? The Soft99 Glaco Glass Compound Roll On is a specialized glass cleaner with dual-compound technology: a combination of small, hard and large, soft abrasive particles removes even the most stubborn dirt such as oil films, fluorine residues, and old sealant remnants — the perfect preparation for maximum durability of any Glaco glass sealant.

The Soft99 Glaco Glass Compound Roll On is the preparatory product in the Glaco series — and thus the most important step that most drivers skip. Any glass sealant can only adhere as well as the underlying glass surface is clean. Oil films from road traffic, fluorine residues from old windshield washer fluids, silicone residues, and wiper streaks form an invisible barrier that drastically reduces the durability of even high-quality sealants. The Glass Compound Roll On solves exactly this problem: The unique dual-compound formula with two different particle sizes cleans the glass surface down to the bare surface — mechanically, thoroughly, and without chemical residues. The practical roll-on applicator with a wide felt head makes application as easy as with the Glaco series sealant products: press, distribute, rinse. With 100 ml content, one bottle is sufficient for numerous applications, as only a few milliliters are needed per windshield.

• Dual-compound technology with two particle sizes. The combination of small, hard particles and larger, soft particles creates a dual cleaning effect: the hard particles break down stubborn deposits, while the soft particles simultaneously polish the surface smooth. In practice, this means: you achieve a cleaning depth that is not possible with conventional glass cleaners — without scratching the glass.
• Removes oil films, fluorine residues, and old sealant remnants. The three most common causes of poorly adhering glass sealants are specifically addressed by the Glass Compound: road oil from traffic, fluorine residues from windshield washer fluids, and silicone residues from old sealants. After treatment, the glass surface is chemically clean and offers maximum adhesion for the subsequent sealant.
• Wide roll-on applicator for quick, even application. The felt applicator covers a large area per stroke and distributes the compound evenly over the glass. You don't need a separate pad or cloth for application — the bottle is also the applicator.

Practical tip from Detailing1: The Glass Compound Roll On is the crucial difference between a glass sealant that lasts three weeks and one that lasts three months. Always use it before the first application of Ultra Glaco or Glaco DX. The five minutes invested will double the durability of your sealant.

How Dual-Compound Technology Works on Glass

The Glaco Glass Compound Roll On uses a dual-compound formula specifically developed for glass surfaces. What's special: Two different types of particles work simultaneously. The small, hard particles (comparable to a very fine polishing paste) mechanically break down contaminants — oil films, fluorine residues from windshield washer fluids, lime deposits, and silicone residues from old sealants. The larger, soft particles simultaneously smooth the surface and prevent the hard particles from leaving micro-scratches. The result is a glass surface that feels noticeably smoother after treatment than before. This smoothness is not just visual — it creates the prerequisite for hydrophobic sealants like Ultra Glaco or Glaco Roll On Large to form a uniform, seamless protective layer. Without this preparation, sealant molecules adhere unevenly: the sealant adheres to clean areas, but not to contaminated areas — the result is an uneven beading effect and reduced durability.

Correct Application of Glaco Glass Compound Roll On — Optimal Glass Preparation

The application of the Glass Compound Roll On begins with a rough pre-cleaning: Rinse the glass with water to remove loose dirt, sand, and dust — otherwise, these particles could cause scratches during the compounding process. Shake the bottle vigorously before use so that the compound particles are evenly distributed. Gently squeeze the bottle to release the compound onto the felt applicator, and guide it in overlapping, straight strokes over the entire glass. Apply moderate pressure — you should feel the particles working on the surface. Treat each area two to three times, especially the wiper areas where oil film and fluorine residues accumulate most heavily. After treatment, rinse the glass thoroughly with clear water and dry it with a clean microfiber cloth. Important: Do not use glass cleaner after compounding — many glass cleaners leave residues that impair the adhesion of the sealant. The Glaco De Cleaner is the exception here, as it is specially formulated for the Glaco series and leaves no residue that could harm the sealant.

Why Glass Preparation Makes a Difference — Durability and Results

Glass preparation with the Compound Roll On is the most underestimated factor in glass sealing. In our experience at Detailing1, clean basic preparation doubles the lifespan of any sealant. An Ultra Glaco on an unprepared window typically lasts four to six months. The same Ultra Glaco on a window prepared with the Glass Compound easily achieves ten to twelve months. The reason: Without preparation, contaminants lie between the glass and the sealant, acting as weak points — water penetrates there and locally detaches the sealant. With the Compound, the adhesion is uniformly even across the entire surface, and the sealant only slowly thins out due to mechanical abrasion (windshield wipers, car washes), instead of detaching in patches. This difference is particularly noticeable with long-lasting sealants such as Ultra Glaco or Glaco DX. With shorter-lasting products like Glaco W-Jet, the effect is less dramatic but still measurable.

Glass Compound Roll On vs. Glaco Q — Pure Cleaner vs. 2-in-1

Both the Glass Compound Roll On and Glaco Q contain compound abrasive particles — but with different focuses. The Glass Compound Roll On is a pure, specialized glass cleaner with maximum cleaning power: two different particle sizes, high abrasive concentration, no sealant component. Glaco Q is a 2-in-1 product that combines milder compound cleaning with a hydrophobic coating. In practice, this means: for initial treatment or heavily soiled windows, the Glass Compound Roll On is the better choice because it cleans deeper and removes more stubborn dirt. Glaco Q is sufficient for lightly soiled windows and refreshers, but saves the separate sealing step. The professional variant: Glass Compound Roll On for cleaning, then Ultra Glaco or Roll On Large as a sealant. The quick variant: Glaco Q alone for both in one step — with the compromise of slightly weaker cleaning and shorter sealant duration.

Who is the Glass Compound Roll On ideal for — Purchase Recommendation

The Soft99 Glaco Glass Compound Roll On belongs in the basic equipment of every driver who takes their glass sealant seriously. Users who use long-lasting sealants such as Ultra Glaco or Glaco DX particularly benefit — here, preparation makes the biggest difference in durability. The Glass Compound is also useful for new cars: factory windows often have invisible residues from protective films, transport, and cleaning agents that weaken a sealant. Furthermore, the Glass Compound Roll On is the tool of choice if you want to completely remove an old glass sealant before applying a new one. Combine the Glass Compound with the Glaco De Cleaner for final fine cleaning and a Glaco sealant of your choice for optimal results. For exterior mirrors, we recommend Glaco Mirror Coat Zero after the compound treatment — specially formulated for the more sensitive mirror surfaces.
