Mellow Yellow Refill/Concentrate 500ml - maximum strength wheel cleaner
Mellow Yellow high performance wheel cleaner in concentrate form… so it's double the strength than the standard spray. Therefore, dilute it 1:1 with water to refill the 500ml Mellow Yellow spray bottle, or use it neat for refurbishing wheels and brush it on (maybe use a Dodo Juice Hog Brush).
Remember that dilution ratios are just a guide, so you could even dilute it to weaker ratios than 1:1 to suit your application (say, if you clean the wheels regularly and they don't get very dirty between washes).
Remember that this is a strong acidic product and sensible precautions must be taken during use. If a milder cleaner is required, use Dodo Juice Ferrous Dueller pH-neutral wheel cleaner, or the even gentler Supernatural Wheel Cleaner.
