PHOSCLEAN is an AQIS compliant CIP acid cleaner specifically designed for the removal of scale, rust & precipitates from lines and equipment & tanks in food, beverage & dairy industries.
RUST CONVERSION (Metal Priming & Preparation)
Remove oil, grease & loose scale with a free rinsing water based alkaline degreaser such as PREDATOR, TRIPLE 2 or MULTISAFE.
If necessary strip paint with paint stripper.
Once surface is paint & free of loose scale dilute PHOSCLEAN 1:3 with potable water to make standard solution (330mls per Litre).
Apply diluted product to surface & allow to dry in order to penetrate deep rust & to leave surface in a suitable condition for painting with an oil based primer.
Drying times are variable & are primarily dependent on temperature.
Note: PHOSCLEAN requires time to chemically destroy rust & it is not necessary to use expensive rust inhibiting paints.
Zinc rich paints are not recommended.
PHOSCLEAN like all preventative measures will slow but not stop rust from re-occurring.
Treated surfaces left uncoated may experience further rusting or flashing so it is important to paint surfaces soon after surface is ready for painting.
SURFACE RUST, BORE STAIN & TARNISHING
Dilute PHOSCLEAN 1:4 with warn potable water to make standard solution (250mls per Litre).
Simply submerge the rusty parts, leave for a few minutes & then check until satisfactory.
Wipe or wash off on completion.
As it is not always possible to soak surfaces in a bath apply diluted PHOSCLEAN to surface with a damp cloth, sponge or fine steel wool & keep wet.
Once applied allow time to penetrate & work on surface.
If surface is porous, prone to runoff or is alkaline (concrete or limestone) a recoat will almost certainly be necessary.
TIP: Remember surfaces took a long time to scale, rust or encrust & the process to remove this also takes time.
STAIN REMOVING & GENERAL CLEANING
Dilute up to 1:10 with warm water, however a dilution of 1:4 is recommended for most applications.
Apply diluted PHOSCLEAN & allow a few minutes to work & then wipe or hose off.
Do not allow to dry.
Deeply encrusted stains may need further applications & some slight agitation with a brush or light sourer to promote penetration.
Remember to keep the surface wet with product & do not allow to dry as process will halt.
TIP: Always pre test an inconspicuous test area before tackling your job.
Pre wash using AQIS Alkaline Detergent such as AC222 or Hercules then flush.
Then use PHOSCLEAN at a dilution to suit your requiremts (from neat to 1:100).
TIP: Always allow up to 5 minutes of contact time to dissolve scale & precipitates.
Always rinse food contact surfaces with potable water after use.
Always pH adjust waste water to pH 7 with sodium hydroxide before release/ disposal.
SITUATIONS TO AVOID IN USE
Avoid contact with Sodium Hypochlorite solutions (bleach), colorbond, anti-fouling paint, marble, anodised or galvanised surfaces & aluminium. Always pre test an inconspicuous test area before tackling your job.
