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 is designed to reverse the effects of sodium hypochlorite on lead, as well as removing rust stains from render and limescale build up from window glass.
We told him that the product should not be left on lead longer than advised on the label and that the whitening was probably the result of it being left on the lead flashing for too long.
To reverse the whitening effect of the lead we suggested he give the lead flashing a light rub with some Scotch-Brite or the green household mild abrasive pads sold for pot and pan cleaning.
We suggested he follow this with an application of "patination oil" that can be bought from most builders merchants.
This treatment will bring back the dull grey colour of lead that we are used to and will also protect the lead from further staining.
Important: Protect yourself from inhaling white lead dust, or absorbing it through your skin, as it is more than likely toxic.
We hope this information is helpful and inspires you to succeed in your softwashing business.
Cheers,
Ben, Leo
