Every YumCars Order Ships With Our Printed Dilution Guide

Nobody reads the back of a bottle at 7am with a foam cannon in one hand. So we printed a guide, and it goes in the box with every YumCars order.

When the YumCars range landed at our studio, we did what we always do before listing anything: read the safety data sheets, read Yum's own product pages, and used every bottle in the studio. The chemistry held up. The labels were the problem. Some bottles gave no foam cannon figure at all, others gave a ratio with no volume, and even we had to stop and work out what a few of them meant.

If a chemist has to stop and work it out, a customer washing their car on a Sunday morning will just guess. Guessing is how you end up with foam that runs off in seconds or a shampoo mixed three times too strong. So we wrote the YumCars dilution guide.

The guide

Millilitres first, ratios in brackets

Most dilution charts are written as ratios, and ratios are where people go wrong. Does 1:10 mean one part product to ten parts water, or one part in ten? For a foam cannon it hardly matters, because every cannon bottle is marked to the litre. So the guide says it the way you actually mix it: product in first, then water up to the 1 litre line.

That makes 1:10 simply 100 ml, 1:20 is 50 ml and 1:5 is 200 ml. The ratio still sits in brackets for the detailers who think in ratios, but you never need it to get the mix right.

Product	Use	How much
Yum Wash	Wash bucket	100 ml per bucket
Yum Wash	Foam cannon, weekly dirt	100 ml per litre (1:10)
Yum Wash	Foam cannon, heavier grime	150 ml per litre
Yum Citrus	General maintenance	100 to 200 ml per litre (1:10 to 1:5)
Yum Citrus	Very well kept car	50 ml per litre (1:20)
Yum Wheel Foam	Foam cannon	200 ml per litre (1:5)
Yum Reset	Wash bucket	50 ml per 10 litres
Yum Dress V2	Tyres and exterior trim	Neat
Yum Dress V2	Engine bays	200 ml per litre (1:5)
Yum Wash MF	Washing machine	30 ml per load, 60 ml for dirty loads

That is a sample. The printed guide covers the whole range, and each product page on our store carries its own dilution block with the same figures, so you can check a number from your phone at the tap.

The best dilution chart is the one you actually read before you mix.

In the box

Why it goes in every order

A dilution chart on a website only helps if you go looking for it. A printed guide sits in the garage next to the bottles, so the right amount is there when you are standing at the tap with a cannon bottle in your hand.

It also fits how we work. We pick products on their chemistry, and we tell you what the manufacturer claims and what they do not. The guide is the practical end of that: the same care we take reading a safety data sheet, turned into something you can use at 7am. It is free with every order from the YumCars collection, including the Wash Bundle 2.0 and our YumCars 3pH Wash System.

Try it first

Walk in and test on our panels

If you would rather see a product work before you buy it, come to the studio. Walk-ins are welcome at our Heidelberg West studio in Melbourne, and we keep test panels set up so you can try the products yourself: see how Yum Foam clings, feel the slickness of Yum Wash under a mitt, or watch Yum Wheels change colour as it reacts with iron fallout.

You will be talking to the people who use these products every day in the studio, not a sales script. Bring your questions, and bring photos of your car if you want advice on what it actually needs.

Training

In-house training with the products we sell

We also run hands-on training at the studio, using the same products that are on our shelves. It ranges from the wash chemistry masterclass, which covers the alkaline, acid and neutral steps of a proper wash, through to ceramic coating application. We have trained dealership detailing teams as well as enthusiasts working on their own cars.

If you want to understand why a product is dosed the way it is, rather than just follow the number on the guide, that is where to start. Our foam cannon guide and car shampoo chemistry articles are a good primer before you come in.
