I use B&S pads also, but usually use the white or orange which are the firmer euro foam, but that shouldn't make that much difference. I clean with a stiff denture brush (from the $ store) and a MF towel. Like Gabe I'll use a little more Polish with the orange pad than the white.
Here's David Fermani's pointers for using HD Polish from a post a few months back:
**Take a fresh, clean pad of your choice. Again, if this pad hasn't been completely cleaned prior to use, old product residue could still be in the pad and cause dust to fly everywhere. Very important to get this off on the right foot.
**(initial application/prime)Apply 4-5 small drops of product throughout the outer edges of the pad. This doesn't mean the center and this doesn't mean to use water, QD or anything else.
**On medium speed (speed 4 or 5 on a GG for example) work the product in a 2 by 2 foot area using slow arm speed and moderate downward pressure.
**Make 2 to 4 passes. A pass is considered 1 back and forth and 1 up and down movement.
**Wipe & inspect
**Clean pad with either a firm pad brush, compressed air and/or towel.
**For reapplication, apply 3-4 more drop on outer edge of pad.
**Swap to fresh pad after 2-3 full sized panels or when pad begins to be over-saturated with product.
NOTE:
*This product does not break down. You don't need to work this product very long due to the non-diminishing abrasive technology. If you make too many passes, the oils will dry up and dust could result. If you don't clean your pads after each pass session, dust could result.
*There isn't a need, nor was this product designed to be used with water, QD or any other liquid to assist with this products performance.
The only thing I would add is that the different density of the pads require different amounts. Stiffer the pad, more product it needs.
*Keep your bottle closed after use. Store in a cool, dry environment.
*****IMPORTANT*****
*DO NOT overly prime pad.
When using HD Polishing compounds in sunny, outdoor or hot environments/surfaces:
1-Use a little more product
2-Work smaller sections/areas
3-Clean pads well/frequently
4-Be mindful of long work times
