View on Amazon

Moving on to yet another effective surface cleaner that will leave you satisfied with its impact on any floor.

Wet and forget is made to eliminate algae and moss that start to cover your outdoor benches, pathways, etc., over time.

The name ‘Wet and forget’ is inspired by the way it works. You just have to spray the liquid over affected areas and forget the rest-no need to scrub it or wash it off.

The formula works over time by reacting with moisture, rain, and wind. The activation mainly depends on weather conditions.

Follow the instructions on using and diluting the product, then fill it in a gardener sprayer and spray all the corners and crevices, patio, gravestones, fence, roofs, etc.

It requires a fair amount of patience before showing the results, but you will not be disappointed. The results might change if you don’t follow the dilution steps carefully.

You can always contact their customer service to get a better idea of how to use the spray.

Usually, you will have to wait for the rain to activate the spray, so it might not show results immediately after spraying, especially in hot and dry weather conditions.

Ideally, it will take 2-3 weeks to manifest the cleaned surface, but the process can dilate up to several months. This is just how the spray works!

Keep the swimming pool or fishpond covered while you spray the periphery or surroundings because it could be dangerous for the water.

Ensure you keep the spray away from your grass and use it only on the stone surface as it can kill your plantation.

You must wear PPE to use any kind of strong surface cleaner. This, too, requires you to protect yourself while spraying.

No products found.

If you haven’t made up your mind about which concrete cleaner to use just yet then this might become your go-to choice.

Eco-Etch Pro is the perfect pressure washer cleaner for concrete that can surely remove those stubborn stains.

It is manufactured by EcoPro Cote which is popular for bringing eco-friendly products into the market. 

Made from organic ingredients such as acid salt and surfactant, it is effective and safe. It is specially made for concrete. It can easily etch concrete flooring.

It isn’t hard on the concrete so that the surface won’t get damaged, and a good layer of coating is established for protection. 

The company claims that Eco-EtchPro can remove efflorescence altogether. All those salt, calcium, and mineral deposits won’t bother you. It can even remove the sticky mortar.

Usually, the remover uses two key components that are Phosphoric and Muriatic Acid. Both are incredibly harmful to human bodies as they can burn you. Even breathing the air around it will hurt your lungs.

But you don’t need to fret as Eco-EtchPro is entirely organic and safe.

The materials used in making this are strong enough to give you deep and effective cleaning. The Acid won’t hurt you or your vegetation as it is 100% biodegradable.

If it becomes difficult, then you may need to dip a stiff brush in Eco-Pro solution and apply force while scrubbing off the deposited material. 

There is no need to use baking soda to neutralize the PH level of the solution. It neutralizes with water and isn’t harmful at all.
