Serious organic stains removing with Waardse Spray Gel
Waardse Spray Gel is a cleaning agent which will be applied undiluted with a sprayer or brush on heavy lime, manganese and iron. After applying the gel, you can activate it again by using a brush so the gel will start moving (the gel will get white). When the gel saturates you’ll have to apply it again.
- Waardse Spray Gel may not stay on longer than 60 minutes.
- First test it on a small surface due to affecting the base
- Don’t use Waardse Spray Gel on aluminium and copper
This action only has to be done once and then has to be maintained weekly with Waardse Foam FZ.
