Cleaning and Degreasing for Powder Coating

Posted on: April 30th, 2014 by byersbushblog

For many, the first part of the powder coating process, namely the surface preparation, is the most tedious, as it does not produce any necessarily immediately visible results, making it a tempting one to rush.

This temptation should be resisted, however, as adequate surface preparation is essential to guaranteeing a long-lasting, visually-pleasing finish.

The first step in ensuring a thorough clean is to establish what material you’re working with, as some materials suit some methods better than others, and certain materials e.g. aluminium, can actually be damaged by certain cleaners, so to avoid corrosion, make sure you know what you’re working with.

Here’s the most common method of surface preparation.

Pressure wash

Generally, the first step in preparing a given surface for powder coating is to pressure wash it. This removes any loose debris, and can cut through grease faster than other methods of preparation.

Electric pressure washers are extremely convenient, but are best suited to smaller objects, while gas-based pressure washers take some time to start up, but are a good investment if your surfaces are on the larger side.


Here’s where knowing the limits and needs of your material really pay off – the next step is to soak your object with cleaner.

It’s vital that you find the right cleaner for the job. Many manufacturers produce cleaners that are formulated for specific metals, so make sure you’ve got one that corresponds to your chosen metal.

If you’re worried, get hold of some scrap metal, coat it in the cleaner, and allow it to sit for a couple of days. If the metal looks corroded, continue your search for the right cleaner. If not, proceed with the soaking process.


Once you’ve found the right cleaner, you’ll want to soak your object for 10 minutes before utilizing a soft nylon scrubbing brush to attack any stubborn grease or grime that’s refusing to budge.

The best place to do this is in a dedicated parts washer, but these aren’t necessary pieces of equipment in a beginner’s powder coating kit.

This part of the process can be the lengthiest, and the amount of time it takes will depend on the condition of the original part.

If some debris is reluctant to be shifted, rinse your object, repeat the soaking process, leaving the cleaner on for longer time, and continue scrubbing.

Eventually, all the dirt should give in and scrub off with a little elbow grease.
