Just to add....
We have a form member, Jayfro, when he first joined he was having a problem with micro-marring. I sent him a bottle of BLACKFIRE One Step to undo the micro-marring. Here's the link to that thread,
Newb needing some assistance
Now let me tie this back to your topic about re-using pads.
When I was assisting Jay, I'm pretty sure over the phone I told him the best approach would be to use
NEW foam pads.
Why?
Because if the pores in the foam pads previously used could not be 100% completely washed clean to remove the other product, then he would have the same problem - i.e. micro-marring.
I I think I sent him a free bottle of the BF One Step and a copy of my how-to book, I'm not sure if I also sent him some fresh pads or after talking to Jay and explaining the problem of micro-marring due to contamination, that he then purchased some fresh pads? Either way, the pictures shows new pads.
And then in you read through to post #30 - you can see that the combination of the product and clean pads fixed the paint.
SO - when talking about re-using pads - I do it all the time but I start by only using products I trust to utilize great abrasive technology in the first place. That way there's no problems even if 100% of whatever I was using the last time I used a set of pads doesn't 100% wash out of the pads.
Make sense?
