Find a clean object with a well-defined handle. Use the non-handle end of the object to touch/scratch/adjust/manipulate your face. Clean the object regularly.
Working from home, I've designated a kitchen cooking spoon on my desk for this dedicated task. Plastic appears to better than wood, as it is more-readily cleaned and does not absorb facial oils.
Do your own due diligence on this one, but a few years ago I think it was reported that, surprisingly, wooden chopping boards are better than plastic ones (which had been assumed to be better as they're less absorbent, etc.) and actually combat bacteria.
Given Covid19 is reported to - unusually for a virus - last up to a week [check a proper source!] or so on hard surfaces then maybe in this situation wood might also be better???
>"A study by the Food Research Institute in Wisconsin (Ak et al. 1994a and b) compared wooden and plastic boards and came to the surprising result that wood possesses substantially better hygienic characteristics than plastic. After contaminating different cutting boards with bacteria, significantly fewer viable bacteria could regularly be recovered from wooden boards than from plastic boards. These results were confirmed by Gehrig et al. (2000) in a recent study investigating hygienic aspects of wooden and plastic boards regarding the risk of food contamination. Previous studies assumed that the detected reduction in bacterial numbers on the wood surfaces is caused by an antibacterial effect of wood based on several physical and chemical properties of wood. The porous structure and hygroscopic characteristics of wood could remove the water needed by the bacteria for their vital functions and multiplication and thus kill them (Kampelmacher et al. 1971, Schulz 1995). In addition, substances present in wood (e.g. polyphenoles) could be responsible for an antibacterial effect (Willaman 1955, Biswas et al. 1981, Laks and McKaig 1988, Field et al. 1989, Schra¨gle and Mu¨ller 1990, Scalbert 1991, Mu¨ller et al. 1995)"

Viruses have a lipid outer layer, but no metabolism of their own. Sometimes dehydration will break the capsule, sometimes it won't.
Soap is usually quite effective due to saponification physically destroying the virus's capsule, fwiw.
A plastic spoon is probably pretty smooth so easy to clean.
