I posted this on another thread today, but it 's worth repeating.
Concerning the dw method of rifle cleaning...
I've used the DW method several times and have been satisfied with the stock when finished. However, I only use the DW to get rid of small dents and scrtches in the wood surface only. DO NOT-REPEAT DO NOT use the DW method for removing cosmo. Mineral spirits, a brush, a large pan/bucket works fine. If you chose to use the DW to remove cosmo the scenario goes something like this.........works fine on the 1st rifle (whats not to like, right), gee that worked so well on the 1st rifle maybe I could use it on a couple more rifles, yep, they look as good as the 1st one. It becomes the standard way of removing cosmo for you. One day in the shower, you notice the water is no longer draining from the tub, neither is the sink, toilet, or anything else in the house. You call a plumber, who spends most of the day inspecting your pipes and then tells you it will be over $15,000.00 to clear your pipes and replace THE SEPTIC SYSTEM. Cosmo in the pipes is not a good thing once it cools.
BTW- Don't put it in the DW with the dishes, don't use soap, and be sure to stop the DW before it reaches the dry cycle (dries the wood way too fast and may split it).
Hope this helps.
