Koch Chemie Super Foam NTA-Frei // Alkaline Pre Wash Foam 5L
is concentrated 1:50 and lays on a very thick layer of foam. Being alkaline, this product serves as a relatively aggressive pre-treat option to remove everything you can from the paintwork before making contact with it. With an effective dwell time of 4-5 minutes (maximum), you need to be sure to be working cool panels that are out of direct sunlight to ensure there is no negative interaction with the finish; standard procedure with an alkaline solution.
If you know your products or this site in general, I advocate measuring your product. SFN is no different so you're delivering the proper pH onto the surface. Measuring Cups and a 5L tap are suggested for this container.
The scent of this is awesome. Koch Chemie says fruity, I smell a combination of citrus and citronella. Nothing off-putting at all.
As with any chemical in use for cleaning, it's important to understand proper safety and handling procedure. SDS may be found HERE
