Soft99 Glaco Glass Compound Roll On Glass Cleaner 100ml

Get your glass perfectly prepped — the Soft99 Glaco Glass Compound Roll On as the base for any glass coating

What makes the Glaco Glass Compound Roll On special? The Soft99 Glaco Glass Compound Roll On is a specialised glass cleaner with dual-compound technology: a mix of small hard and large soft abrasive particles pulls off even the most stubborn grime like oil film, fluoride deposits and old coating residue — the perfect prep for getting the most life out of any Glaco glass coating.

The Soft99 Glaco Glass Compound Roll On is the prep product of the Glaco range — and with that the most important step most drivers skip. A glass coating can only bond as well as the glass underneath it is clean. Oil film from traffic, fluoride deposits from old screen washes, silicone residue and wiper smear all build an invisible barrier that drastically cuts the lifespan of even a high-end coating. The Glass Compound Roll On fixes exactly that: the unique dual-compound formula with two different particle sizes cleans the glass right down to the bare surface — mechanically, thoroughly, and with no chemical residue. The handy roll-on applicator with its wide felt head makes it as easy to use as the coating products in the Glaco range: press it down, spread it, rinse it off. With 100ml in the bottle, one goes a long way, since each windscreen only takes a few millilitres.

• Dual-compound technology with two particle sizes. The mix of small hard particles and larger soft particles gives you a twofold cleaning action: the hard particles break up stubborn deposits while the soft particles polish the surface smooth at the same time. Day-to-day that means you get a depth of clean you simply can't reach with a regular glass cleaner — without scratching the glass.
• Pulls off oil film, fluoride deposits and old coating residue. The three most common reasons a glass coating won't hold are tackled head-on by the Glass Compound: road oil from traffic, fluoride residue from screen washes and silicone left behind by old coatings. After the treatment the glass is chemically clean and gives the next coating maximum grip.
• Wide roll-on applicator for fast, even coverage. The felt applicator covers a big area per pass and lays the compound down evenly across the glass. You don't need a separate pad or cloth to apply it — the bottle is the applicator.

Detailing1's tip from the shop: The Glass Compound Roll On is the difference between a glass coating that lasts three weeks and one that lasts three months. Always run it before the first application of Ultra Glaco or Glaco DX. The five minutes you put in double how long your coating sticks around.

How the dual-compound technology works on glass

The Glaco Glass Compound Roll On uses a dual-compound formula developed specifically for glass surfaces. The clever bit: two different particle types work at the same time. The small hard particles (think of a very fine cutting paste) break up grime mechanically — oil film, fluoride deposits from screen washes, limescale and silicone left by old coatings. The larger soft particles smooth the surface as they go and keep the hard particles from leaving micro-scratches. The result is glass that feels noticeably smoother after the treatment than it did before. That smoothness isn't just about looks — it's what lets hydrophobic coatings like Ultra Glaco or Glaco Roll On Large form an even, gap-free layer of protection. Without that prep, coating molecules settle unevenly: the coating grabs on the clean spots and not on the dirty ones — and you end up with patchy beading and a shorter lifespan.

How to use the Glaco Glass Compound Roll On properly — optimal glass prep

Using the Glass Compound Roll On starts with a rough pre-clean: rinse the glass with water to get rid of loose dirt, sand and dust — otherwise those particles can leave scratches during the compound step. Shake the bottle hard before use so the compound particles spread evenly. Squeeze the bottle gently to feed compound onto the felt applicator, then run it over the whole pane in overlapping, straight passes. Use moderate pressure — you should feel the particles working across the surface. Go over each area two or three times, especially the wiper zones, where oil film and fluoride deposits build up the most. After the treatment, rinse the glass thoroughly with clean water and dry it with a clean microfibre cloth. Important: don't use a glass cleaner after the compound — a lot of glass cleaners leave residue of their own that gets in the way of the coating's grip. The Glaco De Cleaner is the exception here, since it's formulated specifically for the Glaco range and leaves nothing behind that would harm the coating.

Why the glass prep makes the difference — lifespan and result

The glass prep with the Compound Roll On is the most underrated factor in glass coating. What we see day-to-day at Detailing1 is that a clean base prep doubles how long any coating lasts. An Ultra Glaco on an unprepped pane typically holds four to six months. The same Ultra Glaco on a pane prepped with the Glass Compound easily reaches ten to twelve months. The reason: without prep, grime sits between the glass and the coating and acts as a weak spot — water gets in there and lifts the coating off in patches. With the compound the grip is even right across the surface, and the coating only thins slowly through mechanical wear (wipers, car washes) instead of flaking off in patches. That difference really shows with long-life coatings like Ultra Glaco or Glaco DX. With shorter-lived products like Glaco W-Jet the effect is less dramatic, but still measurable.

Glass Compound Roll On vs. Glaco Q — pure cleaner against 2-in-1

The Glass Compound Roll On and the Glaco Q both contain compound abrasive particles — but with a different focus. The Glass Compound Roll On is a pure, specialised glass cleaner built for maximum cleaning power: two different particle sizes, a high abrasive concentration, no coating component. The Glaco Q is a 2-in-1 product that pairs a milder compound clean with a hydrophobic coating. Day-to-day that means: for a first treatment or heavily soiled glass, the Glass Compound Roll On is the better call, because it cleans deeper and shifts more stubborn grime. The Glaco Q is plenty for lightly soiled glass and top-ups, and it saves you the separate coating step. The pro route: Glass Compound Roll On to clean, then Ultra Glaco or Roll On Large as the coating. The quick route: Glaco Q on its own for both in one step — with the trade-off of slightly weaker cleaning and a shorter coating life.

Who the Glass Compound Roll On is ideal for — buying advice

The Soft99 Glaco Glass Compound Roll On belongs in the kit of any driver who takes their glass coating seriously. The biggest winners are detailers running long-life coatings like Ultra Glaco or Glaco DX — this is where the prep makes the biggest difference in lifespan. It's worth it on new cars too: from the factory, glass often carries invisible residue from protective films, transport and cleaning agents that weaken a coating. On top of that, the Glass Compound Roll On is the go-to when you want to strip an old glass coating completely before laying down a new one. Pair the Glass Compound with the Glaco De Cleaner for the final fine clean, plus a Glaco coating of your choice for the best result. For the wing mirrors we'd go with Glaco Mirror Coat Zero after the compound treatment — it's formulated for the more delicate mirror surfaces.
