SEK Surebond S.R.B. Stain and Rust Buster Sample, 8 oz

What You Get

One 8 ounce bottle of SEK Surebond S.R.B. Stain and Rust Buster, drawn from a factory sealed container and filled here at our New Jersey warehouse.

• 8 ounce sample bottle with a sealed cap, clearly labeled
• The same concentrate as the quart, mix it to match the severity of the stain
• Enough for a test patch, typically several individual spots

You Dilute It to Match the Stain

S.R.B. covers the organic and mineral end of the stain spectrum: rust, moss, mildew, leaf tannin, blood, beverage spills and non greasy food. Because it is a concentrate you mix to match severity, one product replaces several, which is why it is worth understanding before you buy.

A sample lets you find the right dilution for your particular stains without wasting a quart learning. If your problem is petroleum or grease, SEK points you to Oil Extractor instead, and the sample will make that clear quickly.

How to Use the Sample

• Pick two or three different stain types if you have them
• Start with a weaker dilution and increase strength only if needed
• Apply, let it dwell without drying, then agitate
• Rinse thoroughly with water
• Note which dilution worked for which stain before ordering the quart

What S.R.B. Targets

For petroleum and grease, SEK Oil Extractor is the correct product instead. S.R.B. is the non greasy half of the stain problem.

• Rust and mineral staining
• Moss, mildew and algae marks
• Leaf tannin and organic shadows
• Blood, wine and non greasy food spills
