Why DécapBloc

A professional tool at a craftsman's price

01

1.2 mm stainless wire

Stainless steel strands remove corrosion without contaminating the cylinder.

02

Coated shaft

The steel shaft has a protective coating, so the cylinder thread stays safe.

03

13 mm chuck

Fits any power drill or cordless drill. Nothing else to buy.

04

Handmade

Designed and built by a diver, because shop-bought whips were overpriced.

The range

You need both. So we sell them together.

The standard whip cannot reach the neck; the reverse whip cannot reach the bottom. A full clean takes both.

How to use

As simple as a drill

  1. Empty the cylinder and remove the valve.
  2. Tighten the whip in the drill chuck.
  3. Insert the whip into the cylinder before starting the drill.
  4. Clean the bottom and walls with the standard whip, then the neck with the reverse whip.
  5. Stop the rotation before pulling out. Withdraw the reverse whip while turning it slightly by hand so no strand catches in the neck (umbrella effect). Then rinse, dry and inspect.

FAQ

What people ask us

Do I really need both whips?

Yes, for a full clean. The standard whip works the bottom and side walls; its strands do not reach under the shoulder. The reverse whip is made for that area, around the neck.

Which drill should I use?

Any power or cordless drill with a 13 mm chuck, set to 1,000 rpm maximum.

Can it damage the cylinder thread?

The steel shaft is coated along the section that passes through the neck, precisely to protect the thread.

How can I pay? Do you ship abroad?

By card on the site, or by bank transfer against an invoice for clubs. We ship with Mondial Relay across the European Union. Shipping is free from €150 to mainland France, Belgium and the Netherlands; elsewhere, the shipping cost is shown in the cart for your country.
