How to Care for Your GoBlow — PVD and Stainless Maintenance Guide

May 9, 2026 · Shopify API

Most jewellery you own is fragile. It lives in a box, comes out for occasions, and goes back before anything risky happens. GoBlow is the opposite. It's built to live on your body — through the gym, the ocean, the sweat, the shower, the long weekend that doesn't end when you wanted it to. So the care guide isn't about babying it. It's about knowing what this thing can actually survive, and the small handful of things that will damage it if you're careless.

What machined stainless steel can actually handle

machined stainless steel is marine-grade stainless. built for demanding everyday use, watch cases that go diving, and coastal architectural fittings. It is, by any reasonable measure, indestructible at the scale of a piece of jewellery.

Things machined stainless steel doesn't care about:

Sweat. Wear it through every session at the gym. It won't corrode, won't discolour, won't leave a green mark on your skin.
Salt water. Swim in the ocean. machined stainless steel was designed for marine environments.
Chlorine. Pool water is fine. Hot tubs are fine.
Sunscreen, deodorant, cologne, moisturiser. None of it touches the metal.
Hot showers. Steam, soap, shampoo — none of it matters.

The honest answer to "can I wear my Steel GoBlow doing X" is almost always yes.

What actually damages PVD coatings

PVD — physical vapour deposition — gives Black, Gold, and Rose Gold their finish. It's a hard coating bonded to the steel at a molecular level inside a vacuum chamber. Tougher than electroplating by a wide margin. But it's still a surface treatment, which means there are specific things that will hurt it.

Avoid these:

Abrasive cleaners. Anything with grit — Bar Keepers Friend, Comet, scouring powders.
Steel wool, scouring pads, polishing cloths with grit. Microfibre only.
Bleach and bleach-based cleaners. Will dull the surface over time.
Ultrasonic cleaners with harsh solutions. Fine for Steel, risky for coated finishes.

None of this is exotic. If you don't take it through a sandblaster or soak it in chemicals overnight, you're fine.

How to clean each finish

Steel. Microfibre cloth and warm water. If it's properly dirty, a drop of dish soap. Dry it. That's the entire procedure.

Black. Microfibre only. Warm water if needed. No abrasives, no polish, no toothpaste. The high-gloss PVD mirror finish will hold for years if you don't attack it with anything textured. Fingerprints clear in two seconds with microfibre.

Gold and Rose Gold. Same rules as Black. Microfibre and warm water. The colour is in the coating — there's nothing to polish back.

Rainbow. Same again — microfibre, warm water. But Rainbow is different from the coated finishes in one important way.

Why Rainbow is different

The Rainbow finish is a titanium oxide layer grown into the surface of the metal by controlled heat. The colours are caused by light interference through different oxide thicknesses — actual physics, not pigment. There is no layer sitting on top of the steel. The colour is part of the metal surface itself.

What this means in practice:

It can't delaminate, because there's nothing to peel.
It can't fade, because there's no dye or pigment to fade.
It can be scratched — like any metal can — but you won't reveal a different colour underneath.

It's the most durable coloured finish on the entire range, and it needs the same casual care as everything else.

Storage

The one thing worth doing properly: don't tangle it with other metal jewellery. Hard metal against hard metal is the only situation where you'll mark the finish. A small pouch, a hook on the wall, a dish by the bed — anything that keeps it from rattling around in a pile.

The shower question

Yes for Steel — wear it 24/7 if you want. Yes for the coated finishes with two small caveats: avoid long, very hot soaks, and avoid bleach-based products. Most shampoos and body washes are fine. Most people shower with theirs on every day for years and the finish holds.

The chain

The chain is machined stainless steel — the same alloy as the pendant. Same care, same rules. Chains pick up skin oils faster than the pendant simply because they have more surface contact. A wipe down once a week keeps them looking new. If you've worn it through a heavy session — gym, ocean — rinse under warm water before the salt or sweat dries.

The piece that needs the least maintenance is usually the one you wear the most. That's not an accident — it's the reason it's built this way.
