One To Avoid

Garden Xpert Ready To Use Patio Cleaner

We tested the Garden Xpert Ready To Use Patio Cleaner and found it lacking in several key areas. While it offers multi-surface compatibility (other patio surfaces such as driveways, tarmac, and decking) and is easy to apply, the performance left much to be desired.

The biodegradable and pH-neutral formula is a plus, making it safe for children, pets, and the environment once dry. However, these benefits are overshadowed by its inability to tackle stubborn stains, black spots, or heavy grime effectively.

Despite following the instructions, we saw minimal improvement on moderately soiled surfaces. Heavily stained areas required significant scrubbing or the use of a pressure washer, negating the product’s advertised convenience.

While it may suffice for light cleaning or routine maintenance, it falls short for restoration purposes. Overall, this cleaner feels underwhelming and not worth the investment for more demanding cleaning tasks. We wouldn’t recommend it for deep-cleaning needs.

How We Evaluated and Chose the Best Patio Cleaners on the Market

When testing patio cleaners, we didn’t just spray and rinse on our paving slabs—we delved deep into every detail that matters to you. Here’s how we conducted our evaluations:

Preparation

We started by selecting a variety of common outdoor surfaces, including concrete, natural stone paving, block paving, tarmac, and wood. Each surface was treated with typical stains like green algae, moss, dirt, and black spots to replicate real-world cleaning challenges.

For accurate comparisons, we standardised testing conditions such as surface size, weather, and application time.

Application Process

We evaluated how easy each cleaner was to use, from mixing the solution to applying it with tools like sprayers or brushes. We checked for clarity in instructions, ease of dilution, and overall versatility in application methods.

Performance Testing

Performance was at the heart of our tests. We observed the initial effects within minutes and tracked long-term results over days or weeks. We assessed how well each cleaner tackled stubborn stains, grime, and algae, paying special attention to no-scrub or minimal-scrub solutions.

Coverage and Cost Efficiency

Using the recommended dilution rates, we measured the area covered by each product and compared this to its price. This helped us determine the cost-effectiveness of each cleaner, ensuring value for money.

Safety and Eco-Friendliness

We prioritised surface safety by checking for damage, discolouration, or residue left behind after cleaning. We also assessed the environmental impact, favouring biodegradable and pet-safe products.

Durability of Results

To ensure lasting results, we tested resistance to algae and moss regrowth and evaluated how well surfaces stayed clean over time. Cleaners were also exposed to varying weather conditions to test their durability.

Additional Considerations

We noted any extra features that enhanced user experience, such as anti-slip properties, UV protection, or pleasant scents. Packaging quality was also considered—leak-proof and easy-to-store containers scored higher.

Frequently Asked Questions

What Is the Best Chemical to Clean Concrete Pavers?

The best chemical to clean concrete pavers is typically a pH-neutral cleaner or a biodegradable patio cleaner designed for stone surfaces. These options effectively remove dirt, moss, and stains without damaging the pavers. Avoid harsh acids or bleach, as they can harm the pavers and surrounding plants.

Is Detergent Okay to Use With a Patio Cleaner?

Yes, detergent is okay to use with a patio cleaner, provided it is compatible with the cleaner and safe for the surface. Mild detergents can boost cleaning power, but avoid harsh or abrasive ones that may damage the patio surfaces or interfere with the cleaner’s effectiveness.

Is Baking Soda Good for Cleaning Patios?

Yes, baking soda is good for cleaning patios as a natural, eco-friendly option. It can be mixed with water to form a paste for scrubbing stains or sprinkled on damp surfaces to neutralise odours and loosen grime. However, it may not be as effective for heavy-duty cleaning tasks.

What Is a Good Eco-Friendly Alternative for a Patio Cleaner?

A good eco-friendly alternative for a patio cleaner is a mixture of white vinegar and water. This solution effectively removes dirt, moss, and algae while being safe for plants and pets. Other options include biodegradable cleaners made from natural ingredients for sustainable outdoor cleaning.

Do I Need a Power Washer With a Patio Cleaner?

No, you don’t necessarily need a power washer with a patio cleaner. Many cleaners are designed to work effectively with minimal scrubbing or simple rinsing. However, a power washer can enhance results for heavily stained areas or deep cleaning, depending on the surface and cleaner used.
