MAINTENANCE
8.01 Cleaning and care of stainless steel: Stainless
steel will resist corrosion; however, it is not
impervious to it. For maximum life, stainless
steel must receive a certain amount of care.
CAUTION
AVOID SPILLING HARSH CHEMICALS ONTO THE
BATH, AS CORROSION OF THE STAINLESS
STEEL MAY RESULT.
1.
There are many chemical cleaners, but usually
just changing the water and periodic cleaning
with mild soapy water or a non-scratching
scouring power will suffice.
Should algae or other undesirable
microorganisms form on the top of the bath
media, add a little formaldehyde or zephiran
chloride to alleviate this problem.
CAUTION
ELECTROLYSIS CAN DAMAGE STAINLESS STEEL.
THIS CAN OCCUR IF AN OBJECT IS ALLOWED TO
REST DIRECTLY ON THE SURFACE, TRAPPING
MOISTURE THAT BECOMES OXYGEN STARVED
BUT IS SURROUNDED BY WATER CONTAINING
OXYGEN. THE RESULTING ELECTROLYTIC ACTION
WILL PIT OR ERODE THE STAINLESS STEEL.
2.
Should it be necessary to use a media other
than water such as those listed below, limit
the time to a maximum of four hours. Clean
surfaces immediately after use.
Aluminum Chloride
Bichloride of Mercury
Carbolic Acid
Citric Acid (boiling)
Ferrous Chloride
LysolMercuric Chloride
Potassium Permanganate Stanous Chloride
Sodium Hypochlorite
Potassium Thiocyanate
Barium

CAUTION
NEVER USE THE FOLLOWING CHEMICALS:
AQUA REGIA
FERRIC CHLORIDE IODINE
SODIUM AZIDE SULFURIC ACID
3.
Should the stainless steel ever become
discolored by iron rust, use the following
procedure to remove all traces of the rust and
restore the stainless steel.
WARNING
ALWAYS OBSERVE THE FOLLOWING SAFETY
PRECAUTIONS! USE HEAVY GLOVES OR OTHER
ADEQUATE HAND PROTECTION. WEAR GOGGLES
OR OTHER ADEQUATE EYE PROTECTION. WORK
ONLY IN AREAS WITH ADEQUATE VENTILATION.
Prepare a solution of 20% nitric and 1.5%
hydrochloric acid (if preferred, a 2% to 5%
solution of warm oxalic acid may be used).
Swab solution over surface, allowing it to
remain until all rust is loosened. This will
usually take 1 to 2 minutes.
As soon as rust is loosened, immediately
flush with clean water until all acid is removed.
Dry thoroughly.
4.
During operation, quite a bit of condensation
forms on the inside of the gable cover. When
removing the gable cover, have one of its
corners centered above the water bath, so
that the water runoff goes into the bath.
Shaking the cover aids the water runoff. Be
sure to wipe up any water spillage on or
around the bath.
IMPORTANT
THE USER HAS THE RESPONSIBILITY FOR
CARRYING
OUT
DECONTAMINATION IF HAZARDOUS MATERIAL IS
SPILLED ON OR INSIDE THE BATH.
