Highly concentrated, phosphate- and NTA-free, alkaline, high foaming pre-cleaner for car and truck prewashing. The combination of high-quality complexing agents and special surfactants dissolves even stubborn incrustations such as insects, bird droppings, environmental and rim dirt extremely quickly and is therefore ideally suited in particular for heavily frequented carwashes and for non-contact high-pressure washing.

Special corrosion inhibitors ensure high material compatibility with regard to sensitive components such as, e.g., anodized aluminum. Also eminently suited for copolymer dewaxing. Optimally suited as well for biological service water treatment plants. Quick-separating in accordance with ÖNORM 5106. VDA conform to class A: reaction time max. 5 min, max. application concentration 1:300. Class B: reaction time max. 1 min, max. application concentration 1:30. NTA-free version of Vorreiniger B.

Recommendations for use
Depending on the dirt accumulation: precleaning: 1:30 to 1:50. Rim cleaning: 1:3 to 1:10. Copolymer dewaxing: 1:5 to 1:10. Self-service high-pressure washing: 1:300. Apply over whole surface, allow to react for a short time and use a high-pressure cleaner to rinse off thoroughly. VDA conform to class A: reaction time max. 5 min, max. application concentration 1:300. Class B: reaction time max. 1 min, max. application concentration 1:30

Great for Oily, Rash-Prone Skin, But Be Wary of the Residue
Size: 1.7 Fl Oz (Pack of 1)
This sunscreen is a really solid option if you have sensitive, rash-prone, and oily skin like mine. I’ve found it’s one of the few sunscreens that doesn't cause any irritation, which is a huge benefit for me. On top of that, it leaves a truly matte finish, so I don't feel greasy or shiny throughout the day. The only reason I can't give it five stars is that it leaves behind small, dried white bits on my face. They can be a bit annoying and make the application look a little messy. Overall, it's a good sunscreen that works well with my skin type, but the white residue is a definite drawback.

This stuff is magic!
Size: 1.7 Fl Oz (Pack of 1)
I farm and garden. I spend hours outdoors in the summer, and for years, I’ve hated wearing sunscreen because it made my face feel hot and sticky. This sunscreen is none of that. I received a small sample tube of it from the dermatologist and instantly fell in love with it. It goes on smooth and covers well. But the thing I love about it is that I don’t feel like I’m wearing sunscreen once it absorbs into my skin. I forget about it! It doesn’t combine with my sweat and run into my eyes, making them sting. It doesn’t irritate sensitive skin or clog my pores. This stuff is magic and I will be using it daily. It’s not the least expensive sunscreen out there, but it’s worth it!

Terrible white cast
Size: 1.7 Fl Oz (Pack of 1)
You will look like you just got blasted by Jack Frost in the middle of the summer. This sunscreen could double as a hair identifier from the way it clings to each strand, leaving an incredibly noticeable white residue. I am very fair and on my skin itself the white cast is much less obvious/fades, my eyebrows on the other hand? Frostbitten. Snow swept. Bringing to mind polar bears and penguins. It's an alright sunscreen. Does the job. Does not look good while doing it.

Great Product
Size: 1.7 Fl Oz (Pack of 1)
Most importantly, this stuff works! And I absolutely love that it’s not greasy. My face isn’t shiny or slick when i apply it. I’ve had no issues with my skin tolerating this sunscreen.
