Cleanfast Patio & Dash Wall Cleaner 5L

Cleanfast Patio & Dash Wall Cleaner 5L | Professional Exterior Cleaner

Cleanfast Patio & Dash Wall Cleaner 5L is a professional-strength exterior cleaning solution designed to remove stubborn algae, lichen, black spots and deeply ingrained organic contamination from patios, walls and other suitable outdoor hard surfaces. With over 15% active sodium hypochlorite, this is a highly concentrated product developed for demanding exterior cleaning jobs where ordinary household cleaners may struggle to achieve satisfactory results.

Suitable for compatible stone, concrete and tarmac surfaces, Cleanfast Patio & Dash Wall Cleaner reacts rapidly with organic contamination and penetrates affected areas to restore a considerably cleaner appearance. It is particularly useful for patios, concrete paths, driveways, exterior walls and other hard surfaces that have become green, dark, stained or weathered.

Outdoor surfaces in Ireland are continuously exposed to rain, dampness, airborne contamination and changing temperatures. Areas receiving limited sunlight can quickly become affected by green algae, while patios and paving can develop stubborn black spotting and lichen.

Cleanfast Patio & Dash Wall Cleaner provides the strength needed to tackle these difficult exterior cleaning problems.

## Powerful Patio and Exterior Wall Cleaner

A patio can gradually lose its original appearance without necessarily being covered in ordinary dirt. Biological contamination can establish itself across the surface and within porous materials, producing green, grey and black discolouration.

Cleanfast Patio & Dash Wall Cleaner is designed to react with this type of organic contamination.

Its professional-strength sodium hypochlorite formulation provides rapid cleaning action and is particularly useful for heavily contaminated surfaces where extensive manual scrubbing would otherwise be required.

The product can be used by professional exterior cleaners and experienced domestic users looking for a powerful treatment for suitable outdoor surfaces.

Because this is a highly concentrated professional chemical rather than a mild general-purpose cleaner, correct application and appropriate safety precautions are essential.

## Ideal for Patios, Concrete and Exterior Hard Surfaces

Cleanfast Patio & Dash Wall Cleaner can be used on a variety of compatible exterior surfaces.

Typical applications include patios, concrete paths, driveways, paving, suitable stone surfaces, tarmac and compatible exterior walls.

It is particularly effective when an exterior area has developed visible green algae, lichen or black organic spotting.

Different outdoor materials can react differently to strong cleaning chemicals. Always carry out a small test in an inconspicuous location before treating the complete surface, especially when working with decorative, coloured, delicate or unfamiliar materials.

Do not assume that every outdoor material is resistant simply because it appears to be stone or concrete.

## Simple Application Instructions

Correct application helps achieve good cleaning results while reducing unnecessary chemical use.

**Step 1 – Prepare the area**

Remove garden furniture, plant pots, toys, decorations and other movable objects from the treatment area.

Sweep away leaves, loose moss, soil and other debris. This allows the cleaner to make better contact with the contaminated surface.

Keep children and pets away from the work area.

**Step 2 – Protect yourself**

Before opening or handling the product, put on suitable chemical-resistant gloves, protective clothing and eye or face protection.

Never handle this product with bare hands.

**Step 3 – Test a small area**

Apply a small amount to an inconspicuous section and check the result before proceeding with the entire area.

This is particularly important on coloured, decorative or unfamiliar surfaces.

**Step 4 – Apply carefully**

Apply the product evenly across the contaminated area using suitable chemical-resistant application equipment.

Concentrate on green, black or heavily affected sections, but maintain reasonably even coverage to avoid an inconsistent finished appearance.

Avoid creating excessive spray or mist.

**Step 5 – Allow time to work**

Leave the cleaner on the surface long enough to react with the organic contamination. Do not allow unnecessary contact with surrounding materials.

The reaction can begin quickly, particularly on green algae and similar organic growth.

**Step 6 – Rinse thoroughly**

After the appropriate contact period, rinse the treated surface thoroughly with plenty of clean water.

Make sure chemical residue is removed from the cleaned area.

**Step 7 – Inspect the result**

Allow the area to settle and inspect it once cleaning is complete. Severely contaminated surfaces may require a second controlled treatment rather than excessive product during the first application.

## Excellent for Green Algae and Black Spots

Green algae is one of the most noticeable problems affecting patios, paths and walls. Damp weather and shaded conditions allow it to return repeatedly, particularly during cooler and wetter periods.

Black spotting and lichen can be even more difficult to remove.

Standard detergent may remove surface dirt without adequately treating established organic growth. Pressure washing can provide a significant visual improvement but may not always remove deeply established black spots.

Cleanfast Patio & Dash Wall Cleaner combines chemical cleaning power with rapid action against these difficult forms of exterior contamination.

For heavily affected surfaces, results can often be improved by allowing the chemical to perform the cleaning work rather than immediately attempting to wash it away.

## Professional Strength for Difficult Cleaning Jobs

The major difference between Cleanfast Patio & Dash Wall Cleaner and many everyday patio cleaning products is its strength.

Containing over 15% active sodium hypochlorite, it should be treated as a professional-strength cleaning chemical.

This concentration provides substantial cleaning power but also means the product needs to be handled responsibly.

Using more product than necessary does not automatically provide a better result. Controlled application, adequate contact and thorough rinsing are more important than simply flooding the surface.

Professional exterior cleaners can use the product as part of patio, driveway and wall restoration work, while competent homeowners can achieve excellent results when all instructions and safety precautions are followed.

## Important Safety Guidelines

Cleanfast Patio & Dash Wall Cleaner contains strong sodium hypochlorite and requires careful handling.

**Always wear suitable chemical-resistant gloves and eye or face protection.** Protective clothing and appropriate footwear should also be used to reduce the risk of accidental skin contact.

Avoid breathing spray or mist. When applying the product, use controlled methods that minimise airborne droplets.

**Never mix this cleaner with acids, acidic cleaners, ammonia or other cleaning chemicals.** Mixing sodium hypochlorite with incompatible chemicals can release extremely dangerous gases.

Never experiment by combining patio cleaners together.

Keep the product in its original labelled container and make sure the cap is securely closed after use.

Store it upright in a cool, secure and well-ventilated location away from children and pets.

Avoid unnecessary contact with metals, fabrics, painted surfaces and other materials that may be damaged or discoloured by strong bleach-based chemicals.

Take particular care around plants and lawns. Prevent direct application to vegetation and avoid allowing concentrated chemical to collect around plants.

Do not use the product in confined, poorly ventilated areas.

If accidental contact with the eyes or skin occurs, rinse immediately with plenty of clean water and follow the product safety information. Seek medical advice where necessary.

## Keep Children and Pets Away

Children and animals should not be present while the cleaner is being mixed, handled, applied or rinsed.

Keep them completely away from the treatment area until cleaning is finished, chemical residues have been thoroughly rinsed away and the area is safe for normal access.

Do not leave buckets, containers, application equipment or unused solution unattended.

After completing the job, clean application equipment appropriately and wash your hands thoroughly even when protective gloves have been worn.
