Yum Cars Foam
Yum Foam is a pH-neutral pre-wash designed to safely loosen and lift dirt before your contact wash.
Key Benefits
- Effective Pre-Wash Cleaning: Emulsifies dirt and grime so contamination can be safely rinsed away.
- pH-Neutral Formula: Safe on waxes, sealants, and ceramic coatings without degrading protection.
- Contactless Preparation: Reduces the amount of dirt left behind before the contact wash stage.
- Multi-Surface Safe: Suitable for paint, glass, vinyl, trims, wheels, tyres, and engine bays.
- Clean Rinse Performance: Designed to rinse away easily without reactivating during the rinse stage.
How to Use
- Initial Rinse: Rinse the vehicle thoroughly to remove loose dirt and debris before applying foam.
- Mix Solution: Add 100–150ml of Yum Foam to a foam cannon and fill the remainder with water.
- Apply Evenly: Coat the entire vehicle with foam, focusing on heavily soiled areas.
- Allow to Dwell: Leave the foam on the surface for 5–10 minutes to break down grime.
- Rinse Thoroughly: Pressure rinse from top to bottom, then proceed to your contact wash.
PRO TIP: For heavily soiled vehicles, pre-treat lower panels with a citrus cleaner before foaming to help break down road film and improve overall pre-wash performance.
Dilution calculator
Pick your container and your ratio, and read off how much concentrate to pour.
A foam cannon does not spray its bottle. It draws from the bottle into the pressure washer's flow, so a 1 L bottle can put 11 L on the car and the ratio in the bottle tells you nothing about what reaches the paint. Measure your setup once and the number holds for every product that quotes a PIR.
Nothing matches that. Check the product's own page for its ratio.
Common questions
-
Parts water to one part product. A 10:1 mix is ten parts water and one part product, so a 1 L bottle takes 91 ml of product and 909 ml of water. A few brands print theirs the other way round, so check the label if a number looks unusually strong.
-
Water first, then the concentrate. Pouring concentrate into an empty bottle and topping it up makes it foam over the top, and you lose some of what you just measured.
-
Most diluted products keep for a few weeks in a sealed, labelled bottle out of sunlight. Write the product and the ratio on the bottle. An unlabelled trigger bottle is how the wrong chemical ends up on someone's interior.
-
Panel Impact Ratio is the concentrate as a percentage of everything leaving a foam cannon, the bottle water and the pressure washer water together. It matters for snow foam and pre-wash only, because a cannon draws from its bottle into the washer's flow rather than spraying the bottle.
-
A syringe or a measuring jug with millilitre graduations. Capfuls vary by bottle and by how full you fill them, and at 256:1 a few millilitres out is a noticeable change in strength.
Amazing product and smells great! Got my car shining!
YumCars Foam has been a really enjoyable snow foam to use. The foam quality is thick, creamy, and clings well to the surface, helping loosen dirt and grime before contact washing.
I especially like how easy it is to work with and how satisfying the whole wash process feels when using it. It rinses cleanly, smells great, and works very well as part of a safe maintenance wash routine.
Overall, a high-quality pre-wash product with a premium feel and excellent user experience. Definitely one of the nicer snow foams I’ve used.
