Top 5 Tips on How to Clean Maintain Copper
Sheets

• Copper has a bright lustrous appeal that loses
  its sheen due to atmospheric corrosion and
  abrasive effect of the materials loaded onto it.
• Copper is a highly malleable and ductile metal,
  which means it can be pressed into thin sheets
  and drawn into extensible wires of shortest
  dimensions.
• This is why you will find copper wires featuring
  largely in the stringed instruments.
• The use of copper sheets is largely witnessed in
  industrial applications and segments like marine
  riveting, automotive body shaping and building
  roofs.
• The challenge that haunts copper sheet segment is
  its durability.
• Copper sheet tends to lose its shine, but with
  proper care and maintenance, they can be returned
  to their original bright yellow or burnt orange
  hue with a consistent shade.

1. Work your way out with the cleaning solvents
Copper sheets can be easily cleaned and given a
sparkling appearance by using dilute ammonia.
They are usually wiped clean or placed in the
ammonia solution for a few hours. The shiny
copper surface retains a matte appeal which
clears into a sheen after a few hours of use.
Lacquer thinners, salt and vinegar and baking
soda are other mild agents used in the cleaning
of the coper sheets.
Hot copper sulphate is anotheruseful agent that
can be used to clean the rusting from the copper
sheets.

2. Water wash and lime bath
Much like home-made cottage cheese production,
copper sheets too are tried in a similar way. The
surface is first cleaned under running hot water
and then treated by a solution of citric acid.
The process involves slight scrubbing but more or
less considered as a non-abrasive procedure.

3. Chemical polishing for the roof
Copper sheets are used extensively as a roofing
material. They are susceptible to moisture and
rivet rusts if not cleaned and maintained for a
long time. Chemical polishing is a key process
that is used to clean the rooftops made of copper
sheets. It can be done using pump-driven nozzles
or a more simple hand polishing methods.
Though a short term procedure, if done right the
copper sheets will retain their look for at least
six to eight months at least.

4. Reverse the galvanic reaction
When zinc comes in contact with copper sheets, it
completes a galvanic reaction leading to a rapid
corrosion. Copper and its alloys witness
accelerated corrosion due to presence of
moisture, acids and salts in the atmosphere or in
the surrounding, especially in outdoor locations.
Avoid physical or electrical contact between
the two participating metals to restrict
corrosion. Painting and physical buffers prove to
be reliable arrestors in stopping corrosion.
Professional copper sheet maintenance experts
recommend insulation using non-conducting gaskets
and grommet-type fasteners. The reversed galvanic
structure prevents the seepage of water, thus
stopping the galvanic corrosion of the copper
sheets. A quick tip Copper sheets should
always be cleaned using a water-based emulsifier
or a mildly alkaline cleaner with pH less than
12. Avoid exposure to sunlight and acids
immediately after giving it a citric bath.
