Scotch-Brite Clean and Strip XT Pro — Green vs Purple, Which One Do You Need?

The disc we reach for first — and why it’s earned that spot in our workshop.

Every workshop has that one product that just gets used without thinking about it. For us, when it comes to weld prep, rust removal or stripping thick paint, that product is the Scotch-Brite Clean and Strip XT Pro disc.

We’ve been running these in our own workshop for two years. Here’s what we’ve found — and what you need to know to pick the right one for the job.

What it actually does

The Clean and Strip XT Pro is a non-woven abrasive disc — aluminium oxide or silicon carbide mineral bonded into an open nylon web. That open web is the key to how it works. Unlike a grinding wheel or a flap disc, it doesn’t load up with material. It stays open, keeps cutting, and delivers consistent performance from the first pass to the last.

It’s designed for aggressive surface prep — removing heavy rust, thick paint and corrosion, and cleaning welds — while the nylon construction means it conforms well to irregular surfaces and performs cleanly on edges without chunking.

Green vs Purple — which one do you need?

We stock two variants. They’re not interchangeable — each has a specific application.

Green — Scotch-Brite Clean and Strip XT Pro Extra Cut (Aluminium Oxide, A/O Extra Coarse)

 

This is the more aggressive of the two. Aluminium oxide mineral removes the top layer and refines down to bare metal. Use this when you need fast, effective removal — heavy rust, thick paint, weld spatter cleanup. It will scratch the base material, which is exactly what you want when you’re going straight to weld or prime.

• Heavy rust and corrosion removal
• Thick paint strip
• Weld prep — cleaning and prepping the joint
• Post-weld cleanup and spatter removal

Purple — Scotch-Brite Clean and Strip XT Pro (Silicon Carbide, Sic Extra Coarse)

 

Silicon carbide cuts differently to aluminium oxide — sharper initial cut, slightly less aggressive overall. The purple disc is the better choice when you need controlled removal without cutting as deep into the base material. Good for surface conditioning on softer metals, or where you’re working close to a finished surface.

• Controlled paint and coating removal
• Surface conditioning on aluminium and softer metals
• Prep work where base material integrity matters

Available sizes

We stock both variants in 115mm and 125mm to suit standard angle grinders. Both sizes are available in cases of 5.

• 115mm x 22mm — suits most 4.5″ grinders
• 125mm x 22mm — suits 5″ grinders

Why it performs better than alternatives

The common alternative is a grinding wheel or wire cup brush. Both have their place, but neither does what the Clean and Strip does. A grinding wheel is faster but removes more base material than you often want. A wire brush cleans but doesn’t prep the surface chemically or mechanically the way an abrasive does. The Clean and Strip sits in the middle — aggressive enough for heavy contamination, controlled enough that you’re not reshaping the workpiece.

The high-strength fibres also mean it holds up on edges — an area where cheaper non-woven discs often fail early.

What we use it for at Wallace Heron

In our workshop, the green disc is the first thing on the grinder before any weld. Fast, thorough, and it doesn’t leave behind anything that’ll compromise the joint. We also use it for stripping older equipment coming in for repair — it handles years of paint and surface rust without grinding through the metal underneath.

The purple gets used when we’re working on aluminium or when the job calls for a cleaner finish before painting — the cut is controlled enough that you’re not fighting the surface afterwards.
