I keep a jug of 30% H2O2 in the cabinet; its useful for all kinds of things, from killing fungi/bacteria to bleaching wood.  

There's also a jug of 30% vinegar.  Then there's the citric acid powder, oxalic acid powder (rust removal), potassium dichromate (oxidizing mahogany without staining holly inlays),  butyl cellosolve (2-butoxyethanol) (great glass cleaner*), sodium benzoate (food grade, preservative for my pickles, 0.01%).  Then all the usual solvents for finishing, and probably some other stuff.  

BTW, after cleaning up the stinky tool, pour or spray it with acetone; it will dissolve the surface a bit and leave it factory smooth.  Only a small amount is needed.

* make your own glass cleaner that does not streak:  1-2% butyl, 10-15% alcohol, and water.  The butoxyethanol costs about $11 per pint and makes gallons of glass cleaner, at about $1 per.  A national glass company replaced a large window in our home and gave me an aerosol can of cleaner that worked better than anything I had ever used.  Went back to get more and they wanted $22 a ca; no go.  Took the can to work and handed it to the head of our analytical lab and told him to tell me the ingredients - that what it was.  So, for the last 20 years, I've been making glass cleaner for the neighbors.  The only drawback is a little odor; the commercial stuff covers that with a reodorant (perfume), which I suspect may be what causes the streaking, perfumes being oily stuff.
