Thanks guys, yes
@Holiday only basic household kits will address a lot of the issues when the main problem is soap scrum. Given the blade in this is 1969 this has likely been sitting unused for around 50 years, a lot of basic dirt and grime accumulates in that time.
Cheap toothpaste is a simple, mild, polish
@rhodes96 - so my first choice. It is also fairly water soluble so rinsing as you scrub tends to ensure that you don't leave residue behind. The toothbrush is a cheap medium or firm one too. I know some people who swear by
Denture Brushes which are probably very similar.
Well
@Pbgoose the lighting at night does help. Looking at it now in the daylight you can see all the flaws.
There are some fine scratches on the plastic cover - hoping that
Plastx will help get them out.
In the adjustment mechanism under the head you can see scum and detritus. As the paint is already gone from the number the ultrasonic will help sort that out.
With the soap scum out of the way the spots of
verdigris on the handle are more obvious. There are lots of
home remedies for removal and even simply soaking overnight in Coke (acidic) is known to work - but it can also compromise more of the plating. Ammonia (or other high alkaline products) are as bad if not worse!
I tend to stick with the Victoria and Albert Museum approach -
less is more.
I will ultrasonic the razor next and then see how it is looking. At the same time I will use Plastx on the case.
More to come!
