I purchase 75% phosphoric acid at a commercial chemical establishment...They sell house cleaning chemicals for commercial cleaning folks. They sell sodium hydroxide (caustic soda) outstanding for etching aluminum outside a closed space, nitric acid, sulphuric acid, hydrochloric acid, mek (methyl ethyl keytone), trichloroethylene (I think thats correct spelling), etc....phosphoric will burn your hands but even at 75% it is not that caustic and putting hands in it momentarily to remove the object youre cleaning is NOT that bad with a little cold water hand rinse (and moisturizing crème as one weeney suggested), the damage is minimal and not generally lasting. Chemicals are easy to find especially in the city and buying them over the internet might get you an inquiry from your local DEA officer, Police department or sheriffs dept. I can state that with some degree of accuracy as I was an elected District/County attorney for approximately 14 years in Texas and had a close relationship with the authorities.

Granted not 85% but from what I read on the thread I don't need that strength. Did look for jasco and did not see it. But it would be easy to overlook frankly.
