A very relieved customer in the UK sent us this email after using Net-Trol to rescue his new patio:
Just a note to say how delighted I was with Net-trol and the results were amazing. The rust stains came out completely!!! As you know I had tried umpteen different chemicals and solutions but only Net-trol worked.
It was a huge relief to my wife and I as we had just spent £6000 on the stone and having it laid. I only applied the grass treatment 2 days before the patio was to be sealed!!
Once again many thanks to you.
David initially contacted us after trying many other products in an attempt to remove rust stains from his sandstone paving caused by metal furniture left on the slabs whilst he treated his lawn with a fungicide. Having spent a lot of money on his new patio he was understandably anxious to find something that would remove the stains.
We suggested that he used Net-Trol which as well as restoring color to weathered wood can also remove rust stains from stone and cement. It is perfect for use in the garden as it’s harmless to plants and shrubs and is quick and easy to use. First wet the surface with clean water, then apply Net-Trol with a synthetic brush or long pile roller and agitate the surface with the brush. Leave to stand for 10-20 minutes and then scrub with a stiff brush or use a pressure washer to remove. Repeat the process for particularly tough stains.
As you can see, the patio looks great and David was able to look his wife in the eye again!
