How to Remove Green “Tomato Tar” (Plant Stains) from Hands After Pruning

📌 Quick Summary: The Best Hacks for Cleaning Tomato Hands

Every grower knows the struggle: you go out to pinch a few suckers, and suddenly your hands are covered in that sticky, green/black “tomato tar” that regular soap refuses to wash off. Here is how our forum members get their hands clean when they forget to wear gloves:

  • 🌿 The Sorrel Hack: Crush and rub fresh sorrel leaves on your hands. The natural oxalic acid cuts right through the tomato resin.
  • 🍋 Citric Acid: Keep a shaker of food-grade citric acid powder near the sink. A tiny pinch acts as a natural solvent and scrubber.
  • 🌸 Soapwort (Saponaria): Plant a patch of Soapwort near your outdoor spigot. Crushing the leaves/flowers creates a natural, stain-removing lather.
  • 🧽 Mechanical Friction: Surfactants (soap) alone won’t work. You need friction. An old kitchen sponge (the scrubby side) or a stiff-bristled nail brush is your best friend.

Today, as usual, I was having my morning coffee out in my tomato patch. Coffee cup in one hand, pinching off tomato suckers with the other! New ones pop up every single day. I also pinched off a few megablooms (fasciated blossoms). And of course, I just *have* to do it all barehanded, it’s more fun that way. Honestly, why did I even buy two pairs of cute floral gardening gloves? 🤷‍♀️😁

Out of pure greed, I decided to prune all my tomatoes to 2 stems this year, leaving the strong basal shoots. But my tomatoes clearly have their own plans—more than half of them decided to split into double or even triple leaders on their own. Last year only a couple of varieties did that.

All the plants are loaded with buds now. The cherry *Ciliegino Grappolo* and *Hungry as a Wolf* are starting to bloom. The latter has beautiful, heavily cut foliage with streaks of anthocyanin (purple/black). But I watched a video review of it recently, and it’s supposed to have regular leaves and standard dark fruits with green shoulders. Looks like my seed packet had some genetic segregation going on (it’s a brand-new 2025 release).

I do almost everything barehanded too! I only try to put gloves on when I’m actually digging deep in the dirt. But it is seriously so hard to scrub your hands clean after pruning tomato suckers barehanded… I’ve tried doing it in gloves a few times, but it’s just too clumsy, I can’t feel the delicate shoots.

Good morning everyone!

If I’m outside, I intentionally leave a small Sorrel plant growing right next to my outdoor faucet. If you grab a sorrel leaf and rub it on your hands, the natural acid washes the green tomato stains right off!

If I’m already indoors, I use citric acid powder. Just sprinkle a tiny bit on wet hands, rub them together, and the tomato tar melts away effortlessly. I rarely use gloves either, pretty much only if I’m spraying harsh chemicals.

And I pre-wash my hands outside using Soapwort (*Saponaria*)! I make sure to have at least a little corner of it growing in every single one of my flower beds. The flowers and leaves lather up beautifully and scrub all the green stains completely off. Plus, I really love the smell of it.

I’ve come to the conclusion that the absolute most effective way to scrub tomato greens off your hands is just a small kitchen sponge (an old, retired one from the kitchen works great) under a stream of running water.

Soap and other surfactants are basically useless against tomato resin. You need mechanical friction.

Aleksander, I actually tested a kitchen sponge against a stiff-bristled nail brush… I definitely prefer the stiff brush! But I do lather it up with soap anyway…
