Instead of using water to clean metal, opt for acetone. This dries very quickly, so there will be no delays to your work. If you notice there is rust on the metal, use a rust remover to clear this first. After cleaning your metal with acetone on a clean rag, make sure you don't touch the surface again.
Isopropyl alcohol or denatured alcohol is what you'd typically want to use for metal prep.
Acetone is a decent cleaner and is used to thin quite a few different paints. Denatured alcohol is great for wiping down parts before they are painted. Gets rid of grease and dust, then evaporates quickly. Lacquer thinner or MEK will clean anything.
Do not use mineral spirits, paint thinner, or even lacquer thinner, they all run the risk of leaving undesirable residue behind. The best is a dedicated wax & grease remover from your paint jobber. There has been some very active discussion on this board of using a metal etching prep prior to epoxy.
There are many acetone-based solvents available for degreasing and cleaning metal. Acetone is considered a safer option than many hazardous solvents, because of its low toxicity and strong degreasing capabilities.

Even though both are used as solvent, their applications have differences depending on the industry. In the semiconductor, printed circuit and metal products' industries, acetone is only used to wipe down black ink on copper tubes. For scrubbing, cold rinsing or steam rinsing, IPA solvent is a better option.
Unsurprisingly, water works well as a green cleaning product and pre-painting car cleaner. Soap: Invest in a high-quality car wash soap.
SURFACE PREPARATION
Wash the surface with a commercial detergent, or other suitable cleaning method to remove dirt. Rinse with fresh water and dry with a clean cloth. Remove all oil, grease, wax and petroleum based materials with mineral spirits. Remove loose paint and rust with a wire brush or sandpaper.
While acetone will aggressively strip paint from a wide variety of surfaces, though, mineral spirits is really only effective at cleaning up fresh paint. It can clean brushes and other tools after you finish a project, but once the paint dries, mineral spirits is mostly ineffective.
Use a commercial cleaner such as Trisodium Phosphate (TSP) to make sure everything is deep cleaned. TSP removes dirt, grime, scuffs, soot, and all other manner of soiling.
Many counties have banned mineral spirits due to their toxic nature. Unfortunately, this means that do-it-yourselfers have to find alternatives for the same. Here are a few substitutes that work the same way. Acetone – It is a solvent and hence can be used for cleaning or degreasing.
Yes, you can clean metal with vinegar before painting. Vinegar is an effective, eco-friendly cleaning agent that can help prepare metal surfaces for painting.
Vinegar: Copper, brass, and stainless steel will look brand new when you use this pantry staple. Bicarbonate: You may know it as baking soda, and it's a hero when it comes to shining up copper, brass, gold, and silver.
Apply a galvanized metal primer. Repaint with a high-quality paint.
Sugar soap is a secret weapon when it comes to prep. It cuts through grease and makes the clean up incredibly easy. All you need to do is spray on the sugar soap, scrub it with a sponge and then use clean water to wash it off and get rid of the residues.
To turn your first metal paint job into a successful experience, we invite you to check the next five steps to preparing metal for paint. Clean the surface. To properly prepare new metal surfaces, use mineral spirits to remove grease and apply a rust-inhibitive primer before painting.
Things You'll Need to Prep and Paint Your Car:
Orbital sander with multiple-grade sanding pads. Hand sandpaper in grits from 120-800 for prep to finished sanding. Solvents (acetone/Eastwood Pre) for cleaning surfaces. Masking tape and paper.
Although lacquer thinner may remove oily soils, using it for solvent cleaning is not a good method because it evaporates too quickly. It is also dangerous due to its low flash point. Mineral spirits is a better choice for degreasing and is safer to use.
Rubbing alcohol will not damage a car's paint when used sparingly and in moderation. Diluting rubbing (isopropyl) alcohol to 20% concentration with distilled water is an excellent way to ensure the paint is oil-free before applying a car wax, paint sealant, or ceramic coating.
Acetone is well known as one of the safest solvents to use for cleaning metal. Acetone is often used to clean metal in industrial applications to remove debris and build-up from machinery, as well as 3D printers, and in applications to clean metals before applying paint and other coatings.
Polychem AcraStrip 600 CRR is a water-soluble, non-hazardous, eco-friendly alternative to acetone and other solvents. Like AcraStrip 600 Auto, it was developed to replace a variety of petroleum-based products.
