I live in an area that has very hard water and fighting soap scum is a constant battle. I looked at my Edwin Jagger razor the other day and it just looked so dull and old. Soap scum had made the plated parts look horrible. I have an ultrasonic cleaner that I use to help keep my eye glasses looking good, so I thought I would give my razor a run in the cleaner to see if it helped. I filled the cleaner with clean water and added a little bit of cleaning solution made for ultrasonic cleaners and gave the razor an 8 minute run and now I have a razor that looks brand new. It shines as brightly as the day I bought it. Now, my brush looked horrible compared to the razor. My daily use brush is an Edwin Jagger Best Badger, so I gave it a run in the ultrasonic cleaner. I was almost afraid that the bristles may not come out well and that I might lose the brush. However, after an 8 minute run, the brush came out looking like new. I could not believe the amount of old soap that came out of the bristles. I thought I had rinsed the brush very well after each use, but I guess one cannot really get all of the soap out. Anyway, thanks to the ultrasonic cleaner, I now have a razor and brush that looks as new as the day I purchased them.
