60p item to ‘effectively kill’ white spots on driveways and ‘prevent regrowth’


For those who have an older driveway that was laid some years ago and is covered in white spots, the culprit is almost certainly going to be lichen. 

Lichens are a complex life form comprising of three different organisms in a “symbiotic relationship”. They take at least two years to emerge on new or cleaned and sanitised driveways. 

They spread through the air as pieces break off and then land on another part of the surface. 

They grow and spread very slowly for several years however once established growth accelerates, the spots get bigger and then they can quickly spread to colonise the whole driveway or patio. 

Lichen will thrive in damp and shady conditions so a driveway covered in dirt, moss and weeds will provide lichen with the ideal conditions to grow.

Lichen will not cause damage to a driveway. However, they do look unsightly and can become slippery in winter and wet conditions.

Luckily, paving experts at Lordswoods Groundscare Solutions have shared their main technique to remove white spots from a driveway.

They claimed that sodium hypochlorite, a chemical found in bleach, mixed with water is “very effective at killing any lichen spores”. 

The bleach solution “works very quickly within a few minutes” of just one application.

The paving pros said that one application “will ensure that all lichen spores are dead and will prevent fast regrowth”. 

Bleach solutions containing sodium hypochlorite are hazardous to health so should be handled with care and personal protective equipment should be worn. 

Safety equipment such as goggles, chemical-resistant gloves and a facemask are essential as contact with the skin can cause burns. 

Any splashes on clothes will quickly bleach out colours. Surrounding plants and lawns should be watered thoroughly before and during the application.

The experts highlighted that a solution of three to 3.5 percent sodium hypochlorite is enough to “kill white spot lichen”. This percentage is typical for most brands of bleach.

They added: “Stubborn lichen spots should be agitated with a stiff brush and then repeat the application until they disappear.”

Bleach can be picked up for just 60p at Aldi, 65p at Asda and 70 at Tesco.
