Answer 2

Albertsons grocery shops sell it, or a minimum of the Albertsons close to my domicile used to sell it as much as very at the instant. i could desire to purchase a sixteen fluid ounce bottle of 70% ethyl alcohol by using quantity for a distinctly actual looking fee. The bottle seems merely like the isopropyl alcohol bottle and is bought contained in the comparable area. the kind call of the alcohol is "equivalent line". Like I mentioned, as much as merely very at the instant, Albertsons stocked it. i became there some days in the past and did no longer see it....no remember if or no longer they now no longer carry it or it became jut a fluke that they've been out of inventory i won't say, however the employees didn’t be attentive to something. the best thing approximately procuring for (denatured) ethyl alcohol as a rubbing alcohol form as unfavourable to in a drinkable alcohol form is that there isn't any age restrict and that's in all hazard extra fee-effective.
