What are you suppose to use? The plastic scraper idea is crap!
The picture proves a nice point. Unfortunately, if a machinist gets a hold of an engine that a flat rate technician has touched it probably had a roloc bristle or scotch style touch the engine.
If anyone has a better way to clean a sealing surface that is aluminum or iron, I am all ears.
Thanks for the picture
