It will clean render in a non-abrasive way, with low pressure and a gentle spray that is perfect for thinner renders that could be blasted away with high pressures. Check out our post if <a href=\"https:\/\/www.washyourwalls.uk\/can-you-use-bleach-to-clean-exterior-of-house\/\" target=\"_blank\" rel=\"noreferrer noopener\">can you use bleach to clean exterior of house<\/a>.<\/p>\n\n\n\n<p>Sometimes a stiff broom or brush is required to first dislodge the dirt and mess caused by natural weathering before a coating of soft wash can be applied to the surface to start the render clean.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Jet Washing Process<\/strong><\/h3>\n\n\n\n<p>Perhaps most popularly chosen when you <a href=\"https:\/\/www.washyourwalls.uk\/driveway-cleaning\/\" target=\"_blank\" rel=\"noreferrer noopener\">clean driveways<\/a>, jet washing is another approach that can be used on a property to clean render. However, if the surface is delicate, this option SHOULD NOT BE USED!<\/p>\n\n\n\n<p>Why? Because jet washing simply relies on high pressure and water to remove messes. If render is worn, cracking, or just thin, jet washing can destroy the colour and possibly destroy the complete render altogether.<\/p>\n\n\n\n<p>It also shouldn't be used on render covered in painting, because the paint would be blasted away too.<\/p>\n\n\n\n<p>If there is any sign that the render would be damaged by the process, an alternative cleaning system must be found.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.washyourwalls.uk\/wp-content\/uploads\/2023\/01\/Jet-Washing.png\" alt=\"\" class=\"wp-image-266\" width=\"600\" height=\"500\"\/><\/figure><\/div>\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Steam Cleaning<\/strong><\/h3>\n\n\n\n<p>A steam clean differs from the previous two methods because it doesn't rely on moisture or spray to clean the outside of the building. Instead, steam clean is able to create an effective steam that blasts away messes gently.<\/p>\n\n\n\n<p>It's important to note that only a little water is used in this approach, mostly it's high heat and steam that will remove messes from your wall.<\/p>\n\n\n\n<p>Of course, not all renders can withstand this type of heat, so the building and render type should be taken into account before coating it with steam.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.washyourwalls.uk\/wp-content\/uploads\/2023\/01\/Steam-Cleaning-1.png\" alt=\"\" class=\"wp-image-267\" width=\"600\" height=\"500\"\/><\/figure><\/div>\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>TORC Cleaning Process<\/strong><\/h3>\n\n\n\n<p>TORC is a system that uses water, air, and a fine inert granulate that's able to remove algae, staining, and messes from a wall by creating a vortex of swirling mixture in the TORC equipment to then target the residue on the wall.<\/p>\n\n\n\n<p>Again, this wouldn't be suitable for a painted wall, because you would have to sit back and watch the paint be blasted away as the granulate removed it entirely.<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Cleaning Render Effectively<\/strong><\/h2>\n\n\n\n<p>To maintain your render effectively, you need to choose the right option for your render.

That's why it's really important that professional cleaners handle a high heat steam clean, because those high temperatures are enough to potentially crack and smash windows if you miss.<\/p>\n\n\n\n<p>Besides, specialist equipment is required, that we're sure you don't have lying around the house.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.washyourwalls.uk\/wp-content\/uploads\/2023\/01\/Monocouche.png\" alt=\"\" class=\"wp-image-271\" width=\"600\" height=\"500\"\/><\/figure><\/div>\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Tyrolean<\/strong><\/h3>\n\n\n\n<p>Soft washing is great for tyrolean, because the texture of a tyrolean coating can be damaged by stronger approaches.

It's hydrophobic, so it's naturally protected against organic growth, but general messes can still occur.<\/p>\n\n\n\n<p>A sponge and bucket is fine if you're doing it yourself, but if you want a thorough coating, call in the pros.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.washyourwalls.uk\/wp-content\/uploads\/2023\/01\/Silicone.png\" alt=\"\" class=\"wp-image-274\" width=\"600\" height=\"500\"\/><\/figure><\/div>\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Acrylic<\/strong><\/h3>\n\n\n\n<p>Acrylic render should be treated much the same as silicone - low pressure jet washing with a slow stream of water to ensure it doesn't get damaged will be fine.
