Never buy shower gel again

The bar that lifts engine oil without leaving your skin cracked by Friday — landing on your doorstep before you run out. One bar: hair, body, hands, the lot.

Literally covered in sh1t 😂 the coarse grit is class and actually lifts oil from skin every bit as well as industrial Swarfega-style soap. ✓ Verified Steven, Ballymoney, NI · Mechanic & part-time farmer

Swarfega shifts it. It also wrecks you.

Industrial hand cleaner strips the grease and takes your skin with it. Shower gel just smears it around. There has never been much in between, which is why most lads end up picking the one that hurts — and then buying it again, and again, every time the tin runs dry.

TLDR: one bar that lifts the grease, washes you head to toe, and turns up on your doorstep before you run out.

What the lads actually say

Beats Swarfega hands down. Extremely effective at cleaning hands heavily contaminated with oil — and at the same time gentle enough for the most sensitive skin, without irritation or burning.

As a man that works in a dirty environment, the soap is unreal for cleaning even the toughest of grease and grime. Smells amazing and lathers perfectly.

Scott, Newtownards

The grit in the Atlantic Pine Tar works great for getting rid of all the grease, dirt and coal dust I usually get covered with at work.

Jay, Cranbrook BC, Canada

Smells amazing, the rough texture helps as being a welder I get very dirty. I actually feel clean when I get out the shower — with some shower gels I have to really scrub to get the dirt out my skin.

Ryan, Manchester
Verified Customer

I am a service engineer and work hard and I can still smell good after a 12h shift.

Paul, Alcester
Verified Customer

Works well to remove oil/grease... and I come home from work smelling of BO a lot less. Exfoliating and cleaning, while not being too rough on the skin.

How it works

End of shift to clean hands.

Step 1
Straight off the shift
No scrubbing mitt, no nail brush. Wet hands, warm water.
Step 2
Work it in with the cloth
The Silverback works the lather deep in and scrubs off what the bar lifts.
Step 3
Rinse
The oil comes away with the lather instead of being smeared around.
Step 4
Same bar, whole shower
Hair, body and hands. 21+ showers a bar, and the teak dish stretches it further.

Atlantic Pine Tar and The Celtic Tiger. No subscription, no gifts.
Made by a Dublin lad. Used by mechanics in 14 countries.

I started this in my kitchen in January 2021. No lab, no marketing department — just bars I'd actually use myself. Five years on there's 35 of us in a Sandyford workshop turning out about a million bars a year, still cold-processed 50 at a time. If the first bar you try doesn't become your new favourite, we replace it free. That's the deal.

Straight answers

Will it actually shift engine oil and grease?
Yes. The rough bars — Atlantic Pine Tar, Citrus Cedarwood and the Celtic Tiger — use volcanic pumice and oatmeal to lift it. Work it in with the Silverback cloth and you won't need a scrubbing mitt.
Will the grit wreck sensitive skin?
No — the grit is natural (volcanic pumice, oatmeal), not plastic, and the bars are made to be gentle enough for daily head-to-toe use. Atlantic Pine Tar and Fresh Lime and Aloe are both suited to sensitive skin, and reviewers with sensitive skin regularly say exactly that.
How long does a box last?
Each bar gives 21+ showers. The 3–4 week cure makes our bars much harder than typical handmade soap, and the teak dish stretches them further again. The delivery frequency is set to match, so you get the next box before you run out.
Can I skip, delay or cancel?
Anytime, from your account. Skip a box, push the date back, or cancel outright. No phone call, no retention script, no minimum number of boxes.
Do I get the free gifts every time?
The gifts come with your first box only. The discount is different — it applies to every box for as long as you stay subscribed, not just the first one.
What if I'm not happy with it?
You've got 99 days. We'll replace it free or refund you in full — whichever you prefer. No questions asked, nothing to post back.
Where does it ship from?
From whichever of our warehouses is closest to you — Dublin for Ireland and Europe, London for the UK, Tennessee for the USA, Toronto for Canada. Most orders post within 48 hours.
What if I just want to try it first?
Take the 2 bar one-time option under the kits. No subscription, nothing recurring, and no free gifts — just Atlantic Pine Tar and The Celtic Tiger to see if the grit does what we say it does.
