Product Overview
Stainless steel bristled grout brush, and the most aggressive grout brush in the Hydro-Force range. It is made for grout that has resisted nylon — paint spots, embedded oil and grease, and soil that has worked its way into the pores of cement grout.
The bristles are stiff enough to reach into the pores of the grout, and stainless so they will not rust and leave orange staining in the line the way a plain steel brush will.
Important — Match the Brush to the Surface, Not the Stain
Stainless bristle is aggressive by design. Before reaching for it, be certain about what you are cleaning.
| Surface | Stainless grout brush |
|---|---|
| Cement grout, unglazed porcelain, quarry tile | Suitable |
| Glazed ceramic and porcelain tile faces | Keep the brush in the grout line, not across the glaze |
| Polished or honed natural stone, marble, limestone | Do not use |
| Epoxy grout, coloured or sealed grout, colour-sealed lines | Do not use — it will cut the surface off |
| Vinyl, LVT, timber | Do not use |
If you are unsure what the grout is, test in a concealed corner first. Nylon brushes are recoverable mistakes; stainless is not.
Compatible Handle

When It Is the Right Brush

- Grout that has already been cleaned once with nylon and has not come up
- Deep-pored, heavily soiled cement grout on quarry tile

Operating Advice
- Test first, always. On an unfamiliar floor the cost of testing is a minute; the cost of not testing is a re-grout.
- Work along the line, not across it. Crossing the line drags stainless over the tile edge, which is where glaze chips start.
- Use it as the second pass, not the first. If nylon and the right chemistry will do it, use them.
- Rinse and dry it after acid work. Stainless resists rust; it is not immune to pitting from acid left to dry on it.
Frequently Asked Questions
Will it damage grout?
On sound cement grout used along the line, no. On epoxy, coloured or colour-sealed grout it will cut the surface. On soft stone it will scratch.
Will it rust and stain the grout?
No — that is the reason for stainless. A plain steel brush left wet is what leaves orange marks in a grout line.
Does it come with a handle?
No. It fits the AB22H handle (1 piece).
Should this be my only grout brush?
No. It is the aggressive option. Most grout work should start with nylon — the standing grout brush (AB36) or the Mini Shark (AB111) — and step up to this when that has not worked.
Can I use it on shower walls?
On cement grout, yes. Be careful of the tile glaze and of any silicone in the corners, which stainless will tear.

What We See in the Field
The damage this brush causes is almost never on the grout — it is on the tile either side of it, from working across the line instead of along it, and on colour-sealed grout that nobody identified before starting. Ask what has been done to the floor before, not just what is on it now.
