This week we’re doing a deeper dive on a popular detailing topic, the two-bucket wash method. What is it, how it works, and why you should absolutely be using it on your next detail are just a few of the points we'll cover in this post.
To help walk us through some of the talking points we've employed a very special guest; Jay's McLaren P1! That’s right, the hybrid 3.8L, twin turbo charged, 900+ horsepower, 0-62 mph is 2.8 seconds McLaren P1. There were only 375 of these "rocket ships with wheels" ever made! This was the VERY. FIRST. ONE. to be delivered into the U.S. Jay ordered it in the amazing McLaren Volcano Yellow.
It was out and about over the weekend, and if there’s one thing about these cars, they know how to get dirty. Fast.
Low ground clearance, wide tires (245 in the front, and 315’s in the rear!), and extra aero mean cars like the P1 turn into literal vacuum cleaners when driving. They pick up tons of dirt & dust off the roads, leaves, little pebbles and rocks, small children… you name it. And all that dirt usually makes its way onto the car, and that’s where the fun part of our job sets in… how do you clean the thing?! I mean, it’s only an ultra-rare, million+ dollar hyper car, that most people wont get to ever see, let alone TOUCH – no pressure right?
Enter the two-bucket wash method. A somewhat new tactic in the detailing arsenal, this is (hands down) the first line of defense when it comes to cleaning and detailing a car where you want to avoid leaving scratches and swirls in the paint. And while most of us will never get the chance to own an amazing car like the P1, we’re gonna walk you through some of the basics on how to set up a two-bucket wash system so you can wash your car and care for it as though it’s your very own P1.
First we’re gonna start off with the “why”. Why does it work, and why should you bother with it? When you’re washing any car, you’re working to remove the bonded dirt and contaminants from your car’s surface to reveal the clean glossy finish below. The problem arises when your wash mitt touches the paint. This is where you have the highest potential to impart swirls and scratches into your paintwork.
Let’s walk through the hypothetical steps of the old, single-bucket wash method:
See the issue here? This method only serves to saturate your mitt more and more with dirty water, that you then end up scrubbing back into the surface of your car.
The whole idea behind the two bucket wash method is isolating the dirt you’ve wiped from the surface of the car as much as possible. With each trip to the bucket, you want to rinse your mitt of as much dirt as possible in a second, clean water rinse bucket. Then dunk your mitt back into the soapy wash water.
Here’s the basic tools you’ll need to set yourself up with a 2-bucket wash system.
Start from the top of the car, and work your way down so you finish with the rocker panels last. This under portion of the car is by far the dirtiest – you’ll want to save it for last so you aren’t picking up this dirt and getting it onto the rest of the car.
Dunk your mitt in the rinse water after every couple of panels, then dunk it back into your wash bucket to load it up with suds again. Try to utilize the grit guards and washboard to help knock as much dirt out of the mitt as possible.
With the P1, we took an extra couple of steps to help avoid scratching. First you’ll notice the pressure washer complete with a foam cannon. We’ll do a whole separate video on these, but this is one of the most effective ways to deliver soapy water to the surface of any car. And because the soap & water are your main source of lubrication during a car wash, the more suds you can deliver, the better. Anything you can do to encapsulate dirt particles in lubrication will help to avoid scratching your car’s paint during the wash.
You don’t HAVE to use a pressure washer and foam cannon setup, but we would absolutely recommend you AT LEAST invest in a solid two-bucket wash set up. This is going to be your first line of defense in making sure you aren’t scratching or marring your car’s paint.
We’re sharing the tips & tricks we use to clean and maintain Jay’s collection in hopes that it will help you learn a thing or two about caring for your own car.
