A new concept in paint prep, these decon polisponges 'grab' embedded contaminants in a similar way to clay, but they can be cleaned during and after the detail (instead of being 'used up'). Effectively, it's reusable clay. No need to fold or throw away... they'll last dozens of cars before losing their effectiveness (making them potentially much more cost-effective than standard clay). To use, simply wet and lube a panel in the usual way, then glide the easily-held sponge over the panel, occasionally rinsing the clay pad in the rinse bucket. This medium grade clay pad will remove more contamination, more quickly, than the fine grade pad, but please note that there is still a marring risk (like with mid-grade clay).
