Sadly, it is very common to have rust stains appear on your patio or other stoned areas.
These marks usually appear when your garden furniture or other metal equipment begin to rust due to oxidation caused by the weather. This results in rust stains and spots on your tiles.
These stains can often be difficult to remove and will usually not be able to be removed purely with water. Even a pressure washer doesn’t always work.
However, we have a product called Net-Trol that will remove these pesky marks from your patio.
Learn how in our guide below.
Firstly – Wet the surface
Before application of Net-Trol, you will need to wet the surface with fresh clean water.
Secondly – Apply Net-Trol to the surface
Once the surface is wet, apply the Net-Trol using a stiff nylon scrubbing brush. Work the Net-Trol into the stain with the brush and leave it to work for 10-20 mins.
Finally – Rinse and scrub
Once you have left the Net-Trol on the surface for a sufficient amount of time it can now be removed. Using the stiff nylon brush, scrub the surface and rinse with copious amounts of fresh, clean water. If you have a pressure washer this will make it easier.
If you have very stubborn stains you may need to repeat the process.
Net-Trol is traditionally used as a wood cleaner and brightener, but is also fantastic for cleaning and reviving a wide variety of surfaces such as patio tiles. It is easy to apply, fast-acting and will remove tannin bleed, dirt and even mildew.
Net-Trol is also biodegradable making it perfectly safe to use around plants and animals. We always like to recommend that you thoroughly wet the surrounding grass and plants after you are finished though.
Preventing rust marks
One of the most common ways of having rust marks appear is from rusting garden furniture. To combat this we recommend using an application of Owatrol Oil.
Owatrol Oil is a rust inhibitor that deeply penetrates into the surface to prevent damage caused by moisture whilst also keeping rust marks at bay.

I used fertiliser on my lawn and some pellets got onto my patio and stained my Indian sandstone tiles is the there a product that can be used to remove this
Hi there Dave,
We have had someone use Net-Trol on their sandstone tiles before to remove stains caused by an anti-fungicide, so this might be useful for you as well. It is a safe water-based product so will not damage your tiles: https://www.owatrol.ie/product/net-trol/
I hope this was helpful.
All the best,
