Without doing a wipe down process the finish may suffer "drop back"; be cognizant that drop-back (filling) is an effect, not the action of a single ingredient. The oils, polymers, resins and waxes that are present in many products will ‘fill’ the micro fissures in the clear coat that appear as scratches or marring.
The wipe down process should be carried out both before to ensure a surface that is free of any debris and after to ensure that defects have been removed as opposed to masked by any lubrication oils or fillers left behind after the polishing process. The wipe-down process may need to be repeated to ensure a perfectly ‘clean’, debris free surface
Wiping the finish with a micro fibre cloth you may feel that the swirls have been removed, only to have them reappear after the surface has been washed. After polishing a section, mist and wipe to fully remove residues and reveal the true paint finish. Nothing worse than a client having paid for paint renovation to wash the paint surface and then have paint marring reappear
• Polymer sealants will not form a proper monocular bond with a paint surface if there are any silicone or synthetic oils present, they will also negatively affect durability if not removed
• Silicone will cause surface smearing and will affect abrasives effectiveness, product bonding and durability (See also Silicone Removal
Water-based polishes tend to fill far less than oil-based; but they both contain silicone resins and polymer or wax lubricants. A wipe down after polishing or compounding is used to remove the carrier oils and wax used for surface lubrication and allows you to inspect the surface to determine if the surface is defect free or if further work is required.
When polishing or compounding to remove fine swirls or holograms, it`s easy for residues and / or waxes or oils to settle in the swirls, hiding the true paint finish (drop back).
Prior to the application of a paint protection coating it is absolutely necessary to remove any (mostly invisible to the naked eye) fillers and oils; if they are allowed to remain a white or grey hazing will appear on the paint once the coating is applied. It’s the one thing that keeps those who practice paint correction honest. Paint enhancement (glaze or an oil-based wax) anybody can do. But paint correction is a lot harder and IPA (or equivalent) is a liquid lie detector
Isopropyl alcohol
Also known as IPA is readily available at 70 or 90% strength. It is not considered a ‘strong’ solvent although it will permeate clear coat paint and may stain or soften the paint it will not strip a cross-linked paint. It is generally used and is excellent for removing oils / grease from paintwork before applying your final sealant or wax after polishing, or used to clean stone chips before painting.

The oils, polymers, resins and waxes that are present in many products will ‘fill’ the micro fissures in the clear coat that appear as scratches or marring.
Isopropyl alcohol (IPA) if used undiluted it flash dries (evaporates) rapidly, which lessens surface inspection time and will also redeposit the oils you`re trying to remove. Alcohol and water should emulsify any oils, enabling them to be removed. Be cognizant that isopropyl alcohol contains nothing that can contribute to surface lubrication, so the towels resistance could inflict surface marring, to lessen this affect use a fine nap / short fibre towel, very light pressure and linier motions; especially on less dense (soft) paint
Up to now the most common wipe down solution has been 90% isopropyl alcohol diluted with distilled water at a 1:10 dilution. A Depending on the manufacturer’s requirements the oils used in polishes for surface lubrication can be various grades, the denser the oil the harder they are to remove with a solvent-based wipe down. Isopropyl alcohol (IPA) primarily encapsulates the oils, but once the alcohol evaporates the heavier oils may resettle on the surface.
As an alternative a 1:10 solution of a Limonene (citrus-based) cleaning solvent (Wurth Citrus Degreaser or P21S Total Auto Wash) and distilled water. This multi-purpose, citrus base, concentrated degreaser emulsifies grease and oil without harsh acids or alkalis, enabling their removal, they are 100% biodegradable formula out performs hazardous solvent degreasers. Both products can be diluted with distilled water to the desired strength
Be aware that you may need to repeat this process more than once, perhaps 3-4 times may be necessary. The effectiveness of this process is dependent upon a few factors; strength of product used, surface temp of paint, pressure applied and number of passes will all affect the outcome.
Distilled water
Potable water usually contains a number of microscopic contaminants (turbidity) along with dissolved minerals such as calcium and iron. Distilled water should ideally be nothing but hydrogen and oxygen molecules and virtually all of its impurities are removed through distillation, which involves boiling the water and re-condensing the steam into a clean container (pH 6.0 – 7.5)
Any dissolved solids such as salt, bacteria, calcium or iron remain solid while the pure water converts to a much lighter steam and is drawn out for condensation, leaving most if not all solid contaminants behind. Distilled water is preferred for dilution as it’s a ‘known’ quality, unlike domestic potable water
In larger chemical and biological laboratories, as well as industry, cheaper alternatives such as deionised water are preferred over distilled water.
Application - fill a fine misting spray bottle with a 1:10 solution (Wurth Citrus Degreaser or P21S Total Auto Wash) / distilled water, an then spray the surface you have just polished and allow the solution sit for approximately 15 seconds. Agitate the area with a clean panel wipe or a soft 100% cotton micro fibre towel (you may need to repeat this process) change the towel to a fresh quarter after each panel to ensure oil and debris are not re-deposited and observe.
This should have removed any wax or oils that may have filled any remaining swirls and show the true post-polish surface condition. If a diluted solution doesn’t remove the surface oils perhaps a specific paint preparation product, i.e. DuPont PrepSol II™ may be more suitable
Now using your surface inspection light, shine the light directly on the panel and look for fine swirls. If they are still present, you should be able to see them. If not you will see a clear bright reflection from the panel with a great shine, and clarity
These fast acting solvent cleaners will not leave a film residue

• DuPont PrepSol II™
• Wurth Clean Solve
• Rohm and Haas Acrysol
Notes 1:
1. For dense (hard) clear coat use a very light dilution rate, for less dense(soft)clear coats use a more diluted solution, as use too much alcohol will cause a micro fibre to offer more surface resistance and may cause surface marring.
2. After the paint surface has been subjected to a chemical cleaning its protective layer (s) have been removed and the paint surface left without protection, so it is very important that a wax or polymer protection be applied immediately.

Notes 2:
1. Aromatic hydrocarbons- are the most toxic compounds found in petroleum products and include such substances as para-xylene (benzene, toluene, ethyl benzene, and xylene) which are all volatile organic compounds
2. A strong concentration of solvent (plus heat) will engorge the paint micro pores and cause the majority of paint to swell and may be detrimental to its durability. Be cognizant that paint that is swollen expands and becomes less dense (thin); any rotational force applied may cause the paint to fracture (tear)
