BuildKleen is an innovative masonry cleaner chemical that has no acids, alkalis, biocides, or bleach. An ideal monument cleaner chemical for mortar splashes, algae and dirt in 5 litre or 20 litre bottles as a ready-to-use product.

Masonry Cleaner

We also offer a concentrate version of BuildKleen in 10 litre jerrycans for professional exterior cleaners, see more detail here. With increasing demand for environmentally friendly and safe to use chemicals in masonry cleaning and building sites, BuildKleen offers a great option.

How Does It Work If It Has No Biocide?

This eco masonry cleaner works by using nano-size energy packages that penetrate and get underneath the dirt or algae (many a ‘dirty’ patio or war memorial or masonry like sandstone are in fact living microorganisms called algae that thrive in our damp climate). They do this by breaking the surface tension that holds dirt and algae embedded on a substrate ready for easy removal.

The cleaning action of BuildKleen masonry cleaner is powerful and effective and yet non-corrosive, non-acidic, non-toxic, and non-hazardous and the product is even certified as food safe; it does not kill the green growth as with biocides used in most cleaners and is safe to use near a water course.

How To Apply It:

Use of a pressure washer on low pressure setting in conjunction with the use of BuildKleen masonry cleaner can be helpful to send the loosened dirt on its way after treatment. If you are washing a patio that is monoblocks please use a hood washer to save blasting out kiln-dried sand between the blocks. Brush off leaves, cobwebs and debris before you begin and apply generously with several coats it you are spraying the product.

Apply our eco-friendly masonry cleaner with brush or sprayer, saturate the surface well and then agitate with a brush – ideally wait about 15 minutes before rinsing off the dirt.

Available as a concentrate or ready-to-use UPVC cleaner for fascia and soffits. RoofKleen is a choice of detergent that reduces risk and offers a lasting clean.

UPVC Cleaner

Innovative nano-technology formulation in a product that is made in the UK means this cleaner is safe for pets, humans, plastic surfaces, and in drains, ponds, and water courses.

This product has nano energy particles that penetrate grime, dirt, and algae build-up and break the surface tension bonding soiling to the plastic. This therefore dislodges and loosens the soiling so that it is easily wiped and rinsed off instead of killing algae as biocides do.

Extraordinarily safe to use, the all-natural ingredients of this product are in a pH-neutral solution with water and have a dislodging function to clean the uPVC frames, cladding, or signs.

UPVC Cleaner

Please apply a generous amount to heavily soiled surfaces like conservatory roofs or gable ends agitate and scrub well with a brush and then rinse off with a garden hose or pressure washer. The runoff is harmless (indeed it is food-safe) even if you accidentally drip on passers-by!

Do not dilute the ready-to-use RoofKleen unless for light soiling or some maintenance cleaning. With the concentrate UPVC cleaner version that comes in 10-litre jerrycans we suggest a dilution of 1 part concentrate with 10 parts water.

Maintaining a clean and functional gutter and fascia system is essential for the health and longevity of your home. Clogged rain water gutters can lead to water damage, roof issues, and even compromised structural integrity.

However, when it comes to choosing a gutter and fascia cleaner, the safety of your pets and the well-being of your lawn should also be a top priority. That’s where RoofKleen comes in as a safe and effective solution, safe for grass or near pets.

gutter and fascia cleaner

Gutters and fascia boards are often overlooked when it comes to home maintenance, yet they play a vital role in protecting your property. Gutters collect rainwater and direct it away from your home, preventing water from seeping into your foundation, damaging the roof, or eroding the soil around your property. Clogged gutters and dirty fascia boards can lead to numerous problems, including:

Water Damage:

When gutters are clogged with leaves, twigs, and debris, rainwater can overflow, causing water damage to your home’s exterior and interior.

Roof Issues:

Malfunctioning gutters can lead to water infiltration under your roofing materials, resulting in leaks and structural damage.

Pest Infestations:

Clogged gutters can become a breeding ground for pests like mosquitoes and rodents, causing health concerns for your family and pets.

Fascia Rot:

Dirty fascia boards can promote rot and decay, compromising the structural integrity of your home.

While it’s crucial to keep your gutters and fascia clean, it’s equally important to choose a product that is safe for your pets and lawn.

RoofKleen: The Safe Solution

RoofKleen is a gutter and fascia cleaner that stands out as a safe and effective option for homeowners concerned about the well-being of their pets and the health of their lawns. RoofKleen’s formula is non-toxic, non-hazardous and easily biodegradable, making it safe for pets and the environment. You can have peace of mind knowing that you won’t harm your furry friends or the natural beauty of your yard, need a viton seal sprayer? Have a look at our offering.

Minimal Environmental Impact:

RoofKleen’s eco-friendly approach ensures that any runoff from the cleaning process won’t harm nearby plants, wildlife, or aquatic ecosystems. Safe in drains, ponds or a water course.

Efficient Cleaning:

Easy Application:

RoofKleen is easy to apply, whether you are using a pressure washer or a hand sprayer. It’s a hassle-free solution for homeowners who want to keep their gutter and fascia clean without putting their pets at risk.

Longer-Lasting Results:

RoofKleen’s cleaning power lasts, helping to reduce the frequency of gutter and fascia maintenance. This means less disruption to your pets and lawn over time.

Using RoofKleen

This is a straightforward process that ensures the safety of your pets and grass. Here are some steps to follow:

1. Preparation:

Remove any large debris, cobwebs, and leaf litter from the gutters manually.

3. Application:

Apply the solution to your gutters and fascia boards using a sprayer or pressure washer; agitate well with a semi stiff brush to disturb the soiling and dirt.

4. Rinsing:

After allowing the solution to sit for a few minutes, rinse it off thoroughly with a garden hose or pressure washer. This is an excellent choice for homeowners looking to keep their gutter and fascia systems clean while prioritising the safety of their pets and lawns. It is a non-toxic formula which, along with its ease of use and long-lasting results, make it a standout option.

By choosing RoofKleen, you can ensure the well-being of your furry friends, the health of your lawn, and the longevity of your home. Don’t wait until clogged gutters and dirty fascia boards cause costly damage; take the proactive step of using RoofKleen and enjoy a safer, cleaner home.

To use at its best, apply the patio cleaner generously to a few square metres, scrub in well with a stiff brush or deck scrub, wait a few minutes, and then rise off with a garden hose or pressure washer.

How To Apply StoneKleen:

Wondering what is the best natural cleaner for natural stone? Apply this StoneKleen chemical detergent by pouring on or with a brush, sponge, roller or low-pressure sprayer, saturate the surface well and then agitate with a stiff brush.

If sprayed you will often benefit from more than one application, wait 5 minutes before rinsing off and your brush may need to be rinsed to relieve it of debris and soiling between applications.

The use of a pressure washer in conjunction with this natural stone cleaner is helpful for outdoors but older stone masonry needs care and a low pressure setting and it is a good idea to test an area first – we also have a video of how to apply here.
