I attempted to detail my car yesterday but gave up due to the heat! No not because I'm a pale wuss and didn't want to risk cancer, but I would wash a pnel and within minutes it was dry leaving caked on dirt.
I was using the karcher on mix to cover the car in shampoo/water, then I was going round with the mitt and warm shampoo/water. Meanwhile I was having my mate blast the car with the karcher to keep it wet, rinsing where I'd washed. I think by the end, I'd washed the entire car about 3 times, yet I was getting filthy streaks all over the car. So I gave up haha.
How do you get around this? Where was I going wrong?
