Oxalic acid is used in textile finishing, paint stripping; metal and equipment cleaning; as an intermediate; as an analytic reagent and in the manufacture of dyes, inks, bleaches, and paint removers; varnishes, wood, and metal cleansers; dextrin, cream of tartar, celluloid, oxalates, tartari...
For normal, healthy persons, that risk is nearly trivial provided that great amounts of oxalic acid are not consumed on a continuing, long-term basis. The second effect is not chemical but mechanical: the crystals of oxalate, very small but very sharp, can be large enough to irritate the ...

The safest thing to do when cleaning anything using an oxalic acid solution would be to prevent the solution from going down the drain. Capture the acid solution and take it outdoors to pour onto the ground once you’ve neutralized it. ...
(Horneret al., 1995). While most reports demonstrate calcium oxalate formation external to the biomass, an obvious consequence of oxalic acid excretion (Sayer and Gadd, 1997; Ghariebet al., 1998), other reports have described intracellular formation of calcium oxalate, with some crystals ...
