In this article, Iâ€™ll discuss simple, yet important ways of cleaning your polishing pads both during and after performing polishing work.
After purchasing a brand new polishing pad, we throw it on the polisher, get some polish on it, and have our way with the swirls on the vehicleâ€™s paint.Â Once done with the section, we wipe off the polish residue and below we find a greatly improved finish that is simply glowing.Â Fast forward 1 hour, weâ€™re using the same pad, polish and machine on a section of unpolished paint, but after wiping off the residue we realize the results are simply not the same as the first few sections.
Due to their nature, polishing pads will absorb oils and abrasives from the polishes used with those pads.Â Over a certain period of time and after a certain number of polished panels on the vehicle, the pads will get saturated with both the contents of the polish as well as paint removed from the vehicle during polishing.Â Due to this saturation, the pads will not only lose their corrective ability, but weâ€™ll also see splatter coming out of pads due to all the polish and paint residue sitting within the pads’ pores.Â Dusting at this point is almost a sure thing with most machines.
Here you can see the difference between a fresh pad that has been used on only two sections, roughly the size of a trunk lid, and one thatâ€™s been used for a lot longer during the same polishing session.
As you can see, the pad in the second photo is completely saturated with polish and needs to be cleaned. Below is a side by side comparison of two sections polished with the same machine, same speed, same pad and same polish showing different results due to one pad being over saturated and over used.Â This is composed of three different photos so please excuse any noticeable splices.Â I did it for the purpose of showing the three different sections well and how they compare, rather than trying to show off my skills of photo stitching :).Â While both the left and right sections show noticeable improvement compared to the original paint in the middle, you can easily see how the section on the right, which was polished with a clean pad, came out much better than the section on the left, which was polished with a used, saturated pad.
How to avoid this?
There are two ways to avoid this during a polishing job.Â Best way is to have spare pads of the same size and cutting ability.Â This way, once the original pad starts to become ineffective, you simply replace it with a fresh pad and keep polishing.Â This ensures that youâ€™re getting the most out of all your pads and the best results possible out of the paint.Â Even with the spare pads however, you should be cleaning the pad after each section or two in order to remove all the residue and dust that has formed on the pad surface.Â Here are two methods to do just that:
Cleaning pads during polishing using a plastic bristle brush
As mentioned above, cleaning pads during polishing is important in order to keep up the padâ€™s cutting ability and keep getting good results while correcting the paint.Â To do this, youâ€™ll simply need to purchase a small plastic brush with fairly stiff bristles.Â You can usually find such brushes at any local auto parts store and even some grocery stores.Â Hereâ€™s what the couple brushes I use look like:
Now that you have your brush, letâ€™s put it to good use.Â Once youâ€™re done polishing a section on the vehicle and are getting ready to move to the next, simply grab the polisher, flip it over, and turn it on while pressing the brush lightly against the pad surface.
Yes, itâ€™s that simple!Â The pad will be much cleaner for the next section and will still provide great results until it gets too saturated and needs replacing with a fresh, clean pad.Â Now youâ€™re ready to apply some more polish and keep working.
The machine youâ€™re using determines the method of cleaning the pad during a detail job.Â As you can probably tell, I am using a Flex XC3401 VRG polisher here, allowing me to utilize the rotating force to clean the pad.Â With such tools as the Porter Cable 7424XP, youâ€™re unable to do exactly what I have described above since the pad will all but stop moving once you apply some pressure to it.Â With the PC 7424XP you can simply hold the pad so it doesnâ€™t move and brush away the residue from the surface.Â As you may have imagined, a rotary is completely opposite and has even more rotational force than the Flex 3401XC, so itâ€™s even easier to clean the pad.
Few notes and advice:
- You want to do this away from the vehicle so the dust doesnâ€™t get onto the paint.
- Do not use high pressure with the brush as you might damage the foam on the pad.Â Simply press it lightly against the surface and let the brush and polisher do the work for you.
Cleaning pads during polishing using a towel
The second method of cleaning your polishing pad during a detail job can be used in place or after the above brushing method.Â For this method, youâ€™ll be using a clean general purpose microfiber towel and some ONR in a quick detailer ratio.Â After finishing a section during polishing and/or after performing the cleaning method mentioned above, you will lightly spray the pad once or twice with the ONR QD and let it sit for a few seconds.Â Then press the microfiber towel with moderate pressure against the pad as you turn on the polisher.Â The microfiber towel will absorb a lot of the residue within the pad and the ONR QD will help to soften it up and clean it off the padâ€™s surface.
Few notes and advice:
- As with the brush method, youâ€™ll more than likely need to do some work yourself on a PC 7424XP or similar machines due to the lack of rotational force.
- Practice EXTREME caution, especially if doing this on a rotary polisher.Â If the towel is held too loosely and if itâ€™s not bunched up it can get folded over the pad and caught in the spinning head, resulting in anything from the towel flying onto the floor to a broken wrist.Â So again, be warned and be extremely careful when doing this on the rotary polisher.
- As with the other method, do this away from the vehicle so the dust doesnâ€™t get onto the paint.
Cleaning pads after work is complete
Finally, the last method of cleaning the pads is done after youâ€™re done working on the vehicle for the day.Â The pads have done their job and due to the cleaning methods above theyâ€™ve done it very well!Â Now itâ€™s time to clean them up so theyâ€™re ready for next time.
Itâ€™s extremely important to clean the pads out immediately after use because you donâ€™t want that residue to settle in the pad and get hard.Â Itâ€™ll just be a huge pain to remove later on, donâ€™t ask how I know!Â Make sure to do both methods above once youâ€™re done working with the pads before moving onto the following process.Â Now grab all the pads and move them to the nearest sink.Â Make sure you use a sink where your wife, fiancee, girlfriend or mother doesnâ€™t wash clothes, dishes, etc., because you wonâ€™t hear the end of it for a while.Â Again, donâ€™t ask how I know.
For this, youâ€™ll only need Meguiarâ€™s All Purpose Cleaner Plus (APC+) in a spray bottle, diluted 10-15:1 with water.Â So itâ€™ll be 10 to 15 parts water to 1 part APC+.Â Simply spray all the pads with the APC+ â€śpad cleaningâ€ť spray and let them sit, polishing surface facing up, for a good 3-5 minutes.Â Spray each pad generously but donâ€™t leave them dripping.Â Also make sure to do this in a ventilated area because the smell of APC+ is very strong.
After the 3-5 minutes has passed, turn on the faucet and grab one of the pads, preferably one you sprayed with APC+ first.Â Hold the pad with both hands and, while supporting it from the bottom, massage the entire pad surface using your thumbs.Â This should take 10-15 seconds.Â Once done, keep doing the same massaging on the pad surface, but place the pad under the faucet so the water starts to rinse off the residue coming out of the pad.
After a minute or so, you should see most of the residue come out of the pad and get rinsed off.Â Now youâ€™ll want to hold the pad so the water runs over the entire pad surface, then squeeze out as much as you can.Â Follow that by a little more massaging of the pad surface if any residue remains, then do a final rinse and squeeze to get as much water out as possible.
The pad is now clean and ready for drying.
Drying the pads
You have two options, air dry or machine dry.Â I like to dry my pads in the machine as it tends to be quicker, but I always set the machine to very low or no heat at all so as not to damage the pads.Â If you decide to air dry, make sure to place the pads with the backing facing up.Â This will ensure the water doesnâ€™t settle by the backing and disturb the glue holding the backing and the foam together.Â To help dry the pads, always hold the pad and swing it in the air a few times fairly hard to get rid of some standing water.Â Another option is to use a rotary polisher to sling water out of the pad.Â Simply place the machine head inside the sink, or outside where you wonâ€™t sling water over anything important, then attach the pad and let it run for 20-30 seconds at a pretty fast speed.Â In the photo below, Iâ€™m using a backing plate thatâ€™s actually larger than the pad, whereas itâ€™s probably a better idea to use one thatâ€™s a bit smaller than the pad, but it gets the point across.Â Lastly, once done with the rotary, you can grab a microfiber towel and wrap it around the pad, then wring out the pad so the water is absorbed by the towel.
There you have it.Â The pads will soon be dry and perfectly clean, ready for the next polishing job.
