Q: Is it safe to use Först on a ceramic coating?
A: Yes. Whilst Först is a strong alkaline cleaner it can be used safely on fully cured ceramic coatings but we'd suggest keeping the dwell time low and rinsing thoroughly. Avoid using it on fresh ceramic coatings just to be safe.
Q: Can I apply Först to the entire car?
A: It's best to focus on the dirtiest areas like the lower half and rear of the car. This ensures efficient use and prevents product waste.
Q: How does Först compare to snow foam?
A: Först offers more cleaning power than snow foam because it’s sprayed on at full strength without aeration. This allows for better coverage and more effective grime removal.
Q: Do I need a special spray bottle for Först?
A: Our products come with spray heads to ensure an even and efficient application but for heavy use we'd recommend an IK Sprayer as found on our shop. These are fully chemical resistant and more comfortable to use.
Q: Can I use Först for regular cleaning?
A: Yes, Först is excellent for regular cleaning, especially during dirtier seasons like winter. Its powerful formula makes it perfect for tackling tough jobs. However, if your car has a sensitive or delicate finish (chrome window surrounds, anodised wheel nuts etc) then avoid using the product too much - or even at all - in these areas and rinse thoroughly with minimal or no dwell time. Strong chemicals should be used as sparingly as possible to get the job done. We do pH neutral products for gentler cleaning, like Bubblor and Snö.
Q: I have noticed chalky or milky deposits on dark paint or trim after use. What is this and how can I sort them out?
A: Strong chemicals can briefly weaken softer finishes during use, especially in hot conditions where they can dry out. Never let a strong product dry out and apply it to wet panels only to help avoid this. Once a soft finish (black powder coated/refinished wheels, black plastic trim are classic examples) has been weakened, alkali salts from the product and calcium carbonate (limescale) deposits from hard water can be trapped into the surface giving a milky, cloudy or chalky appearance. Assuming these are merely deposits and not physical etching, you can remove them with a polish (like Skara in our range), waterspot remover or mild acid, or even a microabrasive 'magic' sponge. If light chemical etching has occured, Skara will help to level the surface and bring back lustre and shine. Stronger etching may require harsher polishing techniques or even refinishing.
