Mark,
My favorite clean-up for my sintered laps is using barkeeper’s friend and a scotch pad. It removed the build up rather well. When completed they run smooth and cut well. I usually scrub until the entire surface looks brassy new.

is it sintered or plated. if sintered your wasting a lot of your time, your hitting more metal than diamond. sintered is diamond added to metal powder then heat fused to a solid surface, leaving more metal than diamond surface. your better off using the cheap china made laps who’s surface is mostly all diamond, much faster than sintered. what grit is it? gemmakermz@cs.com
Scott,
I use sinteres lap if I am working on a competition stone. I purchased the sintered laps after ruining my plated solid steel laps after when I took action on some very bad advice. The bad advice I got was to use Aluminum Oxide Dressing Bars to expose more diamond on the plated laps. The aluminum oxide dressing bars are made from, of course, aluminum oxide, which is the second hardest mineral, 9 on the Moh’s Scale. The bars basically stripped the plating and the diamond that was supposedly being held in place by plating.
These dressing bars are actually intended to be used on sintered laps, not on plated laps. I have a dedicated bar for each of my singtered laps.
When ever the lap looses its aggressiveness or starts to leave scratches turn the lap on slowly, give it lots of water and drag the dressing bar across the lap with minimal pressure till the water appears to become cloudy. Then remove the dressing bar, and rinse the lap thoroughly.
