The atmosphere almost totally relies upon the hydro oxygens to clean it. Here is proof from over a dozen major institutions: https://acd-ext.gsfc.nasa.gov/People/Jackman/Liang_et_al_2017.pdf

The abstract and introduction are very clear so this really is a full scientific endorsement for OH and hydro oxygens as a route for atmospheric cleanup, especially methane which is coming online.

Further to this the paper reads: “The hydroxyl radical (OH) is the primary atmospheric oxidant, and reaction with tropospheric OH is the most important removal process for many ozone-depleting substances (ODSs), their replacements and other gases that contain one or more hydrogen atoms, e.g., hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs). Many of these compounds are also potent greenhouse gases (GHGs) and can exert significant impacts on climate [Rigby et al., 2014; Velders et al., 2015]. The rates at which these long-lived gases are removed from the atmosphere, and therefore, their lifetimes, are dependent on the atmospheric OH abundance…
