Special-purpose moss killers

How to Get Rid of Moss on Patio: Three Most Common WaysThere are special-purpose moss killers or herbicides on the market that can help you to kill moss. However, when using these, you need to be careful. Introducing chemicals to nature should be a last resort. You should only use these chemicals if they are not harmful to the environment and if you cannot remove the moss with other methods.

Also, mosses have a unique structure different from that of other plants and weeds. Therefore, regular herbicides cannot kill them. Also, products used to kill lawn moss should not be used on a hard surface like the patio around the home. Many of these contain a high concentration of iron-based substances, which can cause rusting.

Reviews indicate that the Scotts MossEx is one of the best special-purpose moss killers you can buy right now. It works quickly and will not stain the surfaces it is applied on.

Power washing

This method is especially useful when removing a large concentration of algae and moss. If you don’t have this type of equipment, you can always find affordable options on the market.

Apart from helping you to remove the moss, it is also useful for other things. However, if you are using power washing, you need to set it to the correct power level. If it is not set correctly, it might damage the patio.

Also, while this might prove very effective, it will likely require a lot of water. And after using it, you’ll likely need to replace the joint sand between pavers. During operation, ensure that you move the jet of water quickly over different spots.

Reviews praise the Sun Joe SPX3000 as an excellent pressure washer that offers a lot of versatility.

Natural means

There are cheap, natural ways of getting rid of moss on your patio.


One of these ways is natural sunlight.

If your patio is in the shade of trees, then prune the branches to allow sunlight to shine on the patio. If there is anything blocking sunlight, you should also remove them.

Why is sunlight so effective? Well, that is because moss will not grow in dry places that have a lot of sunlight.

Within few days of exposing the affected area to sunlight, you will notice that the moss and algae will dry off and disappear.

What if you live somewhere without plenty of sunlight? How can you cheaply and naturally eliminate moss and algae?

Boiling Water

Well, one thing that you can do to tame algae is to use boiling water. Boil water and pour it on the affected area. You should be careful not to pour hot water on plants or grass that you like. After pouring hot water on the moss, scrub off the moss with a brush.

To use vinegar, pour some into a spray bottle and directly apply it to the moss. You should not mix the vinegar with water because that would reduce the efficacy of the method and might take longer before you see results.

After spraying the vinegar, wait for around 15 minutes before scrubbing the moss away with a broom or your deck brush.
