Chemicals
: Hydrochloric acid HCl technically, concentration approx. 15%, quantity approx.: 24 l,
stain remover RX3
Proceed
: Cut the plastic foil in the double size of the utility space of the machine. Put on protective
clothing. Discharge etching agents from the machine into suitable container. Take up existing
sludges with scraper mechanically and give it to the etching agent. Lift the machine and set it on the
foil. If you do not have an exhaust move the machine to proper ventilated room or outside.
Fill the machine with 15%iger HCl. Close the cover. Run the machine with heating switched on for
several hours. Repeat if necessary the cleaning run the next day.
To Clean from the outside give warm water into a bucket. Add stain remover on a wet sponge and
use it like abrasive powder. Let the paste act on the surface, if necessary moisten again with
sponge. Repeat this procedure, until the marks are faded. Particularly persistent deposits carefully
dab with HCl. To clear rinses thoroughly wipe of machine with a not dripping sponge and clean this
sponge in a second bucket.
Discharge HCl from the machine and store to re-use it again. Close drain valve. If the machine is
not filled again, Wipe off the inside of the machine beginning from the top and working your way
down. Clean sponge in second buck. Do not touch the uncleaned parts of the machines, wear long
sleeved gloves if necessary. Give the contents of the second bucket to the used up etching agent.
Alternatively clean the machine from the inside by test run with water.
Return the machine to its location. Examine whether the glow bare is intact (do not switch on, only
visual check.) If necessary remove the electric case and pull back the rubber seal of the glow bare
to check for any penetrated liquid. In this case you have to exchange the glow bare. Fill the machine
with water and perform for a test run and then exchange the water with fresh FeCl3.
The hydrochloric acid can be used later, in order to dissolve sludge sediments in etching agent. Give
HCl in portions of approx. 0.5l to the dirtily brown etching agent and let the machine run briefly. Do
this so long, until the solution is to a large extent clear again. But: NEVER give Hydrochloric acid to
fresh ferric iii-chloride ! Dispose possible surplus of HCl with used etching agent.
This guidance represents only the fundamental procedure in standard situations. Mistake and
change reserved. Handling the chemicals takes at one`s own risk. Regard safety regulations!
Against FeCl3 marks on clothes, smooth and porous surfaces we supply a highly effective stain re-
mover on organic basis.
Drain the dirty rinse water from floor drain of the rinsing zone. The waste laws demand economical
handling of rinse water. We advise to collect the water from the first rinse a) to compensate evapor -
ation losses of the etching liquid and b) for new FeCl3 solution! After discharging the water sedi -
ment remains in the basins. Take up mechanically and give these it to the used up etching agent.
Dispose surplus rinse water together with the used up etching agent.
