Some weed killers can be Eco-friendly such as Algon which specialize in killing algae & black spot leaving other plants unharmed. Whilst others will kill every kind of vegetation that they come into contact with.
One of the strongest weedkillers you can buy is made by Gallup. 2 litres will treat over 3000 sq. meters. It contains glyphosate so is not the most environmentally friendly of weedkillers but certainly is one of the best.
If you do purchase a weed killer for killing weeds on a driveway or patio you should always apply according to the manufacturers instructions. Some weed killers will need diluting with water whilst others are supplied ready-to-apply and do not need diluting before applying to your weeds.
If you want a very cheap way to remove and kill weeds from natural stone paving slabs you may want to consider using a bleach to keep your paving clean. Although this method is not the most environmentally-friendly way to kill greenery.
To get the best results, always apply weed killers to the weeds and moss when they are actively growing. This is because the leaves will absorb the weed killer through the green leafy parts when growing. The leaves transfer the weed-killer to the root of the plant. This ensures that the whole weed is killed and not just the leaves of the weed.
Burn Weeds Away With Gas Weed Wand

Using a pressure washer to remove weeds is not a recommended method of consistently removing weeds from paving. This is because of the damage that can be caused long-term with the use of a pressure washer.
If you do want to keep using a pressure washer to clean and remove weeds from your paving then why not consider applying a paving sealer after you next clean your paving! A sealer will set your joint sand hard so should help stop the damage done if a pressure washer is constantly used to remove the weeds.
By using a jet washer you could cause the underlying sand structure of materials like block paving to be seriously eroded. This leads to water ingress and loss of substrate strength and ultimately sinking of the paving.
