The oil stain remover from SOLUTIONAR made a positive impression on us.
The sturdy packaging and the enclosed instructions for use make a professional impression. If you follow the instructions on application temperature, material compatibility and outdoor use, you can make full use of the product’s effect and have an effective remedy for stubborn oil stains on paving stones.
Application is very simple and uncomplicated thanks to the pouring spout integrated in the can lid. After a reaction time of approx. 30 minutes, we were able to completely remove some of the stubborn oil st ains on the untreated concrete floor. Simply pour the liquid onto the stains after shaking thoroughly, leave to work until dry and then sweep off.
The large oil stain in our test was already over a year old, the two smaller ones only a few weeks, and the surface is an untreated concrete floor which is not easy to remove.
In addition, this stubborn stain would require and allow for re-treatment. Otherwise, the oil stain remover is easy to use.
The easy storage of the can in the box is particularly positive . All in all, a very good product.
