General Information
Stains
Algae & Fungal Growths - Apply a fungicide
according to manufacturer's recommendations.
Beverage Stains - Scrub the stain with hot
soapy water. For stubborn stains apply a 1:10 diluted sodium
hypochlorite solution (household bleach) use according to the
manufacturer's recommendations.
Chewing Gum - Chewing gum is best removed with
a suitable aerosol freezing agent before scraping it off. Use
according to the manufacturer's recommendations.
Fresh Oil Stains - Soak the oil up with an
absorbent cloth or paper towels. Do not wipe. Then cover the
affected area with a 'dry' absorbent powder and leave for 24 hours.
Repeat until the powder has absorbed all or as much of the oil as
possible. If a stain persists, apply a recommended cleaner
according to the manufacturer's recommendations.
Paint / Woodstain / Varnish - Wet Stain - soak
up the spillage with an absorbent cloth or paper towels. Do not
wipe. For paint - the stained area should be immediately scrubbed
with scouring powder and water. For woodstain/varnish - the stained
area should be immediately scrubbed with detergent and water. Paint
removers or solvents should not be used on stains that are less
than a week old, as this will increase penetration into the
concrete. Dried Stain - scrape off as far as possible. Apply an
appropriate proprietary paint remover, preferably one supplied as a
thick gel. Follow the manufacturer's recommendations or contact the
paint manufacturer.
Wood Preserves / Creosote - Soak the stain with
white spirit and scrub with a hot detergent and water. Finally
rinse thoroughly with clean water, or contact the manufacturer of
the preserver.
