So you have a set of dominoes that look like these. There is hope for them. The first step is to get any dirt and grime that has accumulated through the years cleaned off.
This set of dominoes came to me after someone tried to clean the engraved area. The product used loosed the paint. Many of the pips had some paint loss and the paint was completely gone from the back side of the dominoes.
Clean dirt off dominoes:
Our secret ingredient for this is window cleaner. Any brand will do, the generic brands are just as good as the name brands when it comes to cleaning dominoes.
We have only used the generic blue stuff. I have no knowledge of whether the other color cleaners work just as well or better on dominoes. Once we discovered one that worked we stuck with it.
Simply spray a bit on a paper towel and wipe the dirt off the dominoes. It is surprising how quickly and easily the dirt and grime will come off any surfaces.
Remove flecking paint:
The next thing I did with this set was to pick off any flecking paint.
I used a small pointy tweezers end to just lightly scrape around all the dots and center lines in the dominoes. Loose paint just caught onto the end of the tweezers and flecked off completely.
You should use this same process on the backs of the dominoes also. For this set it was unnecessary as the set engraving paint was completely removed before I saw them.
You do want to make sure you get all loose paint off. If you leave a loose spot of paint, the new paint will just sit on top of this loose spot and end up flaking off.
