Keeping pads clean when polishing a car is one of many important steps when using a machine polisher.
Attempt to use a pad with a speck of grit on it, either from dust in the air, or kicked up from the ground, and you’ll cause more issues than you started with. Normal practice is to lay a machine on its back , perhaps with a cloth over the top of the pad to help prevent contamination or drying out. This is fine until you knock the machine onto its side where the pad can pickup dirt on the edges, or potentially some contaminant is transferred from the cloth onto the pad.
The other consideration is by placing the machine on the floor, you are creating a trip hazard, either for yourself or those around you, which could lead to injury or damage to the vehicle.
Instead, we recommend using a repurposed guitar stand, such as the one in the link below, to hold the machine off the floor – out of the way but still within easy reach. This also has the benefit of holding the polisher by the body instead of the neck – which can damage bearings and shorten the life of the polisher, and reduce scratching to the body of the machine which it would pick up laying on the ground.
