Why Shower Glass Can’t Always Be Restored

by Samantha Campbell in PRODUCT KNOWLEDGE

Over time, shower glass can become stained or damaged beyond repair—and it’s not just about being “dirty.” Here’s what really happens:

1. The Protective Coating Wears Away

Most shower glass panels are treated with a protective coating when they’re made. This coating helps repel water, soap, and grime. But with constant exposure to heat, moisture, and harsh cleaners, this layer wears off.

Once that happens, the glass becomes porous, meaning it starts absorbing minerals, soap scum, and oils—rather than repelling them. This creates deep staining that’s no longer sitting on the surface but has actually soaked into the glass.

2. SHYN Paste: Your Last Line of Defence

The SHYN Paste works by gently breaking into hard surface marks—like calcium build-up or soap scum that’s baked onto the top layer. It’s powerful but still gentle enough not to damage the surface.

But if you’ve tried the paste and other products, and the glass still looks murky, patchy, or frosted, that means the damage is below the surface—it’s no longer a cleaning issue.

3. When It’s Time to Replace

If the glass is no longer responding to any of the SHYN products (paste, degreaser, etc.), it’s a sign the surface has been etched or permanently stained. This is sometimes referred to as “glass cancer.” At that stage, replacement is the only option to restore full clarity.

Dos and Don'ts for Cleaning Wool

DOs for Cleaning Wool Read the label first: Always check for specific care instructions like “dry clean only” or “machine washable wool.” Use lukewarm or cold water: Heat can cause wool to shrink or felt. Use wool-safe detergent: Look for pH-neutral, enzyme-free detergents designed for wool (e.g., Woolmark-approved). Hand wash gently: Swirl or press lightly in water—never scrub or rub. Use the gentle or wool cycle in the machine: Only if the label says it's safe to machine wash. Place in a mesh laundry bag: If machine washing, this reduces friction and damage. Rinse thoroughly: Make sure all detergent is out to avoid residue or stiffness. Dry flat: Lay the item on a clean, dry towel and reshape it as it dries. Store properly: Fold and store wool in a cool, dry place—ideally with cedar to deter moths. ❌ DON’Ts for Cleaning Wool Don’t use hot water: It can shrink and felt wool permanently. Don’t use regular detergent or bleach: These are too harsh and will damage the fibres. Don’t wring or twist wool: This stretches and distorts the shape. Don’t tumble dry: Wool should always air dry to prevent shrinkage and felting. Don’t hang wet wool garments: They will stretch out of shape. Don’t ignore stains: Spot-treat gently before washing so they don’t set. Don’t leave soaking too long: 10–20 minutes max—longer can weaken the fibres.

SHYN Paste

The secret weapon for hard water stains, surface rust, and stubborn marks. When nothing else works — SHYN Paste does.Made from natural ingredients and proudly Australian-made, SHYN Paste is designed to restore surfaces and lift grime that’s too tough for regular cleaners. It’s clay-based, non-toxic, and about 30–40% stronger than Gumption and 30% stronger than marble paste — giving you professional-grade results without damage. From kitchen grime to bathroom build-up, scuff marks to limescale — SHYN Paste brings surfaces back to life. What It’s Made For: Remove Hard Water Stains & Thin Limescale:Designed to break down mineral deposits around taps, drains, shower glass, and fixtures. Treat Surface Rust:Lifts light rust marks from chrome, sinks, and fittings without scratching. Restore Chrome and Silver:Revives dull or stained tapware, handles, and metal fixtures with a natural shine. Remove Scuff Marks:Erases black marks on doors, skirting boards, trims, and walls (safe on glossy finishes — may dull matte or low-sheen paint, so patch test first). Lift Stains from Glass and Stainless Steel:Removes surface discoloration, light grime, and stubborn buildup. Brighten White Grout:Brings tile grout back to life by removing surface grime and revealing the original color. Cut Through Build-Up on Tiles:Works on both floor and wall tiles to remove soap scum, grime, and mild staining. Where SHYN Paste Gets Used Most: You won’t use it every day — but when you need it, nothing else compares. Rangehoods:Cuts through thick, greasy buildup that degreasers and erasers can’t fully shift. Chrome Element Covers:Restores the finish and removes rust-like surface marks. Stainless Steel Stovetops:Lifts water spots, light rust, and discoloration — ideal for tough areas around burners. Stone Benchtops:Gently removes turmeric stains and surface grime (always patch test first). Kitchen Sinks (Stainless):Clears off rust, grime, and water streaks for a full refresh. Walls, Doors & Skirting Boards:Removes black scuffs and grime — best on glossy trims and doors. Avoid matte-painted walls unless tested first. Showers:Use on glass, tiles, frames, and fixtures to cut through years of soap scum and water stains during your first deep clean. Silver Fixtures:Restores shine to tarnished areas gently and effectively. Ceiling Fan Blades (Especially White):Removes black dust marks and stuck-on grime without damaging the finish. Glass & Windows:Cuts through surface marks, limescale, and years of buildup where cloths and water fall short. How to Use It Properly: SHYN Paste is clay-based, which means it needs to stay present on the surface during cleaning.Don’t underuse it — many people make the mistake of applying too little. Apply a visible layer and let it sit momentarily to break down grime before scrubbing or wiping. Always use a non-scratch cloth or sponge, and follow up with a wet SHYN Ultimate Microfibre Cloth, then dry with the SHYN Drying Cloth for best results. Patch Testing & Surface Safety Because every surface is different — and you don’t always know its true condition — it’s essential to always do a patch test first. On painted surfaces and stainless steel, SHYN Paste can leave fine scratches if scrubbed too hard. The harder you scrub, the more likely it is to dull the finish or leave micro-scratches.Used correctly and gently, it performs beautifully — just don’t overdo the pressure. Why People Love It: Made from natural, non-toxic ingredients Stronger and safer than common pastes Australian owned and made No harsh smell or chemical irritation Brings back results that most people thought were ruined
