How-to tips for using Benz Oxy Cleanze to remove oxidation from lead


A customer asked us: "I put Benz Oxy Cleanze on a client's lead flashing. It's come up very bright and from a distance looks white. Is that normal?"


We replied that Benz Oxy Cleanze:

  • reverses the effects of yellow and brown sodium hypochlorite (sh, hypo) oxidation on lead
  • removes rust stains from render
  • kills rust on steel fittings
  • kills rust on cast iron downpipes
  • and removes limescale build up from window glass.

How long does it take Oxy Cleanze to remove staining from lead?

Sodium hypochlorite stains on lead are best treated with Oxy Cleanze asap after the staining has occurred.

Oxy Cleanze should not be left on lead longer than advised on the label. Whitening can be the result of it being left on lead flashing for too long.

To reverse the whitening of lead we suggest giving the lead flashing a light rub with Scotch-Brite, or the mildly abrasive pads sold for pot and pan cleaning.

Health & Safety: Always wear appropriate PPE to protect yourself from inhaling lead dust, or absorbing it through your skin.

How to bring back the original colour of lead

An Oxy Cleanze treatment can be followed up with an application of "patination oil" which can be bought from most builders merchants.

This treatment will bring back the dull grey colour of lead that your customers are used to seeing, and will also help protect the lead from further staining.
