If both sides of the felt pad are soft to touch then water will flow equally through either side therefore, it does not matter which side goes up. However, if one side of the felt feels rough to touch, it has been treated to keep fibers from migrating or piling after cleaning. When using this felt pad, it is best for the water to flow through the soft felt side first.

The smaller number of microns, the smaller the holes in the polishing pad. In this case, the 50 microns will trap much finer particles than the 100 or 200 microns.

Our polishing pads trap very fine debris and can clog up as quickly as 24 hours of usage alone. To extend the life of your polishing pad, place it below a regular pad like our Classic Bonded pad where water flows through the Classic pad first, then the polishing pad can last up to 1 to 2 weeks before cleaning is required.

You want the water to flow through your regular filter pad first to trap larger particles before the water flows through the polishing pad. This will keep your pad lasts longer before it needs to be cleaned or replaced.

You can clean our polishing pad by rinsing it in fresh water, wringing it out, and repeating this process until the water runs clean. If you ever need to deep clean our polishing pads, they are durable enough to be cleaned in a washing machine.
