Look at it this way. Corals have gotten along with each other for millions of years, with all the stuff that grows and crawls.
Coral survives being sat upon by crabs, crawled over by worms, put in days of darkness from storms, tail-swatted by fish, and sloshed by pretty strong waves. It survives algaes, clams, sponges, and all sorts of adjacent growth. It survives ammonia better than fish can.
It does have pests: we assume you took care of those by dipping, and in the case of soft coral, especially zoas, not only dipping but holding for magnifying-glass inspection in a week's qt in case eggs (unaffected by the dip) give you nudibranchs.
The best intervention in your tank does not involve fingers, once your coral is set in place. THe best intervention involves test kits which delicately sip a bit of water and advise you to supply the conditions that favor your corals. Water condition is everything. You can also use water flowing through GFO to remove pest algae, and you can alter your chemistry by the judicious, test-accompanied, use of calcium, alkalinity buffer, and magnesium, which stony corals and clams use so fast water changes can't keep up.
In general, your hands bring body oils, or worse, the last soap, deodorant, hand cream, suntan lotion, or pet dander you ran into, not mentioning engine oil, furniture polish, dish soap, Windex, and other real untidy things you may work with.
Do not use, in your tank, any toothbrush or sponge or gloves labeled as 'antimicrobial.' Know what the bacteria protecting your tank are? Microbes. If these have a microbe-killer on them, they're not good.
If you MUST reach in, wear 'exam gloves' available, yes, in large men's sizes as well as women's, via internet or your local pharmacy.
