Vinegar for Impressions?

[bamontgomery]

Hi, all. My family and I only got into fossil hunting in July, but we already have made a few trips to collect them since them. Most of what we've found are small impressions in larger rocks. It's nothing that would likely impress anyone, but we like them. I would also like to clean them, and have seen a few YouTube videos showing how to use vinegar to remove dirt and some of the surrounding surrounding rock. If I put a fossilized impression in vinegar for a few hours, would it destroy it? If so, what would be the best way to clean/prepare them?

Give citric acid & a handful of dollar store tooth brushes a try. I use mesquite thorns for picks & string trimmer string if you don't have thorns. Works great for coins & relics to get concrrtion off without scratching.
