SRW Products EF Efflorescence Remover Specialty Clean

Dissolve the white mineral haze that dulls hardscape installs with the SRW Products EF Efflorescence Remover Specialty Clean. This specially-formulated, ready-to-use cleaner attacks efflorescence — the salt deposits that migrate to the surface as moisture wicks through concrete pavers, brick, clay, and cast stone — and restores the original paver color. Contains no muriatic or hydrochloric acid, so it’s safer for surrounding metals, vegetation, and skilled hands than traditional masonry-acid cleaners.

Why EF Efflorescence Remover?

• Acid-free chemistry: safer for surrounding hardware, metal post bases, irrigation lines, and landscaping than muriatic-acid cleaners — and safer to handle
• Restores original color: dissolves the white salt veil and brings back the saturated paver color buyers see in the showroom
• Ready-to-use: no measuring, no batching — pour, scrub, rinse
• Reseal-prep ready: clears the salt-deposit barrier so a fresh sealer can bond directly to the paver surface
• Two job-sized formats: 1-gallon jug for spot cleanup and small patios, 5-gallon pail for full driveways and commercial walkways

Which Size Should I Buy?

• 1 Gallon (covers up to 200 sq ft of concentrate) — small patios, accent walls, contractor service calls, retaining-wall caps
• 5 Gallons (covers up to 1,000 sq ft of concentrate) — full driveways, large patios, commercial walkways, multi-room paver installs

Application

1. Wait 60–90 days for new pavers to cure before applying EF.
2. Prepare the surface: sweep thoroughly to remove joint sand, dust, debris, and loose material. Spot-clean stubborn stains first with the appropriate SRW Specialty Clean product (CDX, RE, M3C, or OC).
3. Saturate the surface and surrounding area — including all vegetation — with clean water. The project must remain wet throughout the cleaning process.
4. Dilute (optional): for light haze, mix EF 1:1 with water in a watering can. For heavier deposits, use full strength.
5. Apply to the wet surface in 200 sq ft sections.
6. Scrub immediately with a stiff bristle brush. Apply additional water as needed to keep the area saturated. Two-person application is recommended.
7. On inclines, start at the highest point. Scrub from the bottom of each section, pushing excess EF up and over the work above.
8. Rinse immediately with clean water until all foam disappears. Re-rinse adjacent vegetation and surrounding surfaces.
9. Repeat if necessary. Let the surface dry completely.
10. Wait 24 hours minimum before applying an SRW Paver Seal product.

What Not to Use It On

• Sealed surfaces — strip the sealer first with SS Sealer Stripper
• Wetcast or natural stones (limestone, travertine, marble) — acid-sensitive substrates
• New pavers (less than 60–90 days cured)

Safety

Wear eye protection and rubber gloves when applying. Avoid prolonged contact with metal — can etch finishes over time. Saturate vegetation before AND after application to dilute any runoff. Keep from freezing — freezing damages the formulation and may rupture containers.
