Product Information

A. Absolutely. When applied correctly, Mould Remover will completely remove all mould growth and kill the spores. This will prevent mould from regrowing after treating the area and negates the health risks associated with inhaling mould spores. Using a dehumidifier: Dr Andy Whittamore, an in-house GP at Asthma UK, says, “Some people find that dehumidifiers help to dry the air and prevent damp and mould. But you must get the setting right, or they can leave the air too dry and make you cough.” Dehumidifiers can remove excess moisture in the air, which can help stop mould from spreading and ultimately prevent it from returning. By reducing moisture on surfaces rich with organic material, you’ll drastically reduce the likelihood of mold growth. The ingredients of Wet & Forget patio cleaner are reactivated each time it rains. And there are plenty of opportunities for that in the UK! This product prevents regrowth for at least six months, although it can keep working for up to 12, making it the best patio cleaner for long-lasting results. To use this patio cleaner, dilute 1-part cleaner to 4-parts water, then apply with a garden sprayer or watering can. There’s no need for scrubbing or rinsing (which is always excellent news!).

In step two when the Mould Remover is sprayed onto the surface it starts to kill the mould and loosen the staining. Then in step three the idea is to extract the mould from the surface. If you’re satisfied with step two, you can apply the mould remover onto your surface as directed on the label.You should take care when using this product, as it’s highly toxic to aquatic habitats. You should also take care not to spray it near plants. Apply in dry conditions when no rain is expected for up to 8 hours but you should also avoid applying it during intense sunlight. Aspergillus is a green or yellow mould that appears in circular shapes on carpets, mattresses and walls

If you’ve tried other patio cleaners in the past, you’ll likely find that this product (and its active ingredients) help achieve a cleaner patio for longer. Overall though, this product is very easy to use, simply spray it onto the patio after diluting, or use a watering can. After that, you can just let it get to work. Mould on bare wood can be harder to remove than that on painted wood —a light sanding after removal can really help. (Image credit: Getty) Which products remove mould from wood? When it comes to cleaning the patio, you’ll want to avoid reaching for the pressure washer too often – no matter how satisfying it is. Although a pressure washer can be a good option for cleaning the patio, they are far more expensive than patio cleaners and certainly require you to put more work in. Plus, a pressure washer can cause damage to the patio if used too often. Portable pressure washers generally have less power than mains powered models, so this could also be a decent alternative.HG’s Mould Spray is loved by many (including Mumsnet users), experts and previous consumers because it is affordable, effective and works in as little as 10 minutes. How we chose our recommendations This stuff worked a treat," says Amy. "I had an old bottle lying around and sprayed it on. I waited just over five minutes and wiped and off it came. I was actually pleasantly surprised how easily it came off. Note, it did leave a bit of a chlorine smell like a swimming pool, which I didn't mind as it made the bathroom smell clean but it might bother some." What causes mould to grow on wood?

Dettol Mould and Mildew [Remover] is amazing. If that doesn't work, you have real issues!” (Tried and trusted by Mumsnetter peachgreen) Our verdict MoldArmor Rapid Clean Remediation is a mold remover that’s safe for use on a long list of non-porous surfaces, including laminate, sealed fiberglass, acrylic, glass, sealed grout, glazed ceramic, sealed granite, and vinyl. This makes it a particularly great defense in damp or humid areas of the home, such as the bathroom, laundry room, or screened porch. It’s safe for both outdoor and indoor use, but be sure you have adequate ventilation, since the fumes of this mold remover can be powerful—similarly to the other products you'll find on this list. Once the treated area has dried, it’ll be fully safe for children and pets. This is because it contains no acid or bleach. If those pesky stains still refuse to budge, it is time to try a solution made from bleach and water. Experts recommend using one part bleach to four parts water —some even suggest adding a bit of washing up liquid in too. Apply the paste on the affected areas and leave to dry. Remove with a stiff brush and wipe clean with a damp cloth. To finish up, spray a mist coat of a vinegar and water mix to help kill off any straggling spores. Can I Paint Over Mould?Cif Perfect Finish Mould Stain Remover can be used around your home and outdoors to clean mould and mildew but is best suited for lifting mould stains in the bathroom, including baths, showers, tiles, showers and grout. Along with sodium hypochlorite, this product also contains bleach, meaning that your surfaces will be mould-free and sparkling clean long after you’ve treated them. You can even use this spray to clean up limescale and stubborn stains such as tea and wine. This Algon cleaner is safe to use on wood and outdoor hard surfaces, which gives you lots of options for what you can clean. Mould is dangerous and can cause all kinds of health issues, from skin rashes to breathing problems. For this reason, when removing mould spores from wood, protect yourself by wearing a mask, eye goggles and long-sleeved clothing —if you have protective clothing you could put on over your usual clothing it will be even better. You should also wear rubber gloves. Of course, one thing that can put us off fully enjoying our outdoor space is an ugly layer of green mould across the patio. Mould, grime, algae can all cause problems; they can be quite slippery and dangerous too!

CLR Mold & Mildew Clear Stain Remover is a great bleach-free formula to treat any residual mold staining. It's compatible with a variety of porous and non-porous surfaces, including wood, natural stone and marble, and tile, so you don't have to worry about delicate surfaces disintegrating. (Though, the product is not compatible with stainless steel appliances.) This product is also part of the EPA's Safer Choice Program, which recognizes certain products as safer alternatives to traditional chemicals. Despite its cleaner formula, the manufacturer still recommends turning on an exhaust fan or opening windows to properly aerate a room while you're using this spray. We also still recommend taking the proper safety precautions before, during, and after since you're dealing with a chemical product and mold.

If you’re struggling with mould lichen and algae on your paving or patio, the Wet & Forget Mould Lichen and Algae Remover may be your best bet. You can dilute it using one part Wet & Forget to five parts water, which means that this bottle containing five litres of solution will make a whopping 30 litres – enough for up to 300 metres squared. You don’t even need to scrub. Just follow the instructions on the container – wet the area, then leave it to do its thing if it rains, even better, as the rain helps to reactivate the product. Products designed to get rid of mold spots work by targeting the spore (or root) of the mold. (Note: this does not mean the root cause, which is moisture.) After you apply the product, most formulas require you to wait a few minutes. During this period, the product is destroying mold spores at the roots with the help of a fungicide. At the same time, other active ingredients, like ammonium in some formula, works to clean and disinfect the treated surface. Many mold removers also work to prevent growth by leaving behind an antimicrobial coating. The "prevention" part of a formula is known as a mildewstat.
