Get out the sandpaper, grinders and wire brushes! Physical removal of rust involves using something harder that the rust you want to remove and using it to wipe off that iron oxide. Wire brushing will take the longest time, sandpaper is better and if you use a power tool or air tool it's even faster.
The amperage rating isn't sufficient (as noted) and it isn't necessarily the same polarity either. You can possibly check if there is a polarity diagram on the adapters. In general, laptop power supplies are not interchangeable. So probably safe and unlikely to catch fire is about the best advice you'll get. posted by chairface at 4:47 PM on December 20, 2007. Thanks; I think I'll just wait and get a new replacement adapter tomorrow-just to be safe.
Also known as: Perchloroethylene, Perc, PCE, PerSec, Tetranec. Chemical reference number (CAS): 127-18- 4. Tetrachloroethylene (PCE) is a nonflammable, liquid solvent widely used in dry cleaning, wood processing, fabric manufacturing, and metal degreasing.In homes, it may be found in suede protectors, paint removers, furniture stripper, water repellents, silicone lubricants, spot removers, glues, and wood cleaners.nformation. People are most often exposed to PCE when they use it in their work, when cleaning or doing hobbies. Breathing: PCE evaporates into the air. People are commonly exposed to PCE by breathing air containing its vapors. PCE can contaminate home air when people use cleaning solvents or other products.
