SEK Surebond S.R.B. Stain and Rust Buster Concentrated Spot Cleaner, 1 Quart
What It Actually Removes
Autumn is the season this product earns its money. Leaf tannin, acorn and berry stains and the moss that follows a wet shaded season are all organic, and they all respond to the same chemistry.
- Rust. From steel furniture, tools, rebar or irrigation water.
- Moss and mildew. The green and black growth on shaded hardscape.
- Leaf and tannin stains. Including the brown ghosting left after leaves sit wet.
- Blood, beverage spills and non greasy food. The patio party category.
- Not grease or oil. Those need Oil Extractor, which is a different chemistry entirely.
Dilution And Coverage
Concentrated means you decide the strength. Start weaker than you think you need and step up, because you can always run a second pass but you cannot undo colour damage.
| Form | Concentrate, dilute before use |
| Coverage, diluted | 100 to 250 sq ft per gallon |
| Speed | Works in minutes |
| Repeat applications | May be needed on severe or set in staining |
| Variables | Surface porosity, texture, stain severity and application method |
Approved Surfaces
- Concrete and clay pavers, stamped concrete
- Masonry, retaining wall blocks and concrete walls
- Natural and manufactured stone, exposed aggregate
- Tile, terrazzo and stucco

Where To Be Careful, Straight From SEK
- Not for asphalt. Do not use it there.
- Wet cast pavers and stamped concrete. These can suffer colour damage, so test carefully.
- Always test a small area first. Verify the surface, the dilution and the dwell time before you commit.
- Respect dilution. Properly diluted it will not damage or etch. Over concentrated is a different story.
