CARE AND CLEANING OF SCALE
Powder Painted Steel
While powder painted steel is attractive and so durable that it will last many years longer than
ordinary painted steel, it is desirable to clean it thoroughly on a routine basis. There are three
basic things that should be remembered when cleaning powder painted steel.
1. Do not use wire brushes, abrasives, or cleaning tools such as steel pads and scrapers,
which will scratch the painted surface. Instead, use soft cloths or plastic scouring pads.
2. When possible use treated water. Hard water can leave behind deposits. Soft water is
much gentler on the painted steel’s surface.
3. Avoid the use of acetone, thinner or other volatile solvents and abrasive type cleaners for
cleaning. If required, a mild solvent such as mineral spirits can be used to remove oil,
grease, tars, wax, and similar substances. Use a cloth dampened with mineral spirits and
apply only to areas that are contaminated. Follow up the use of this mild solvent with
detergent cleaning and rinsing.
Stainless Steel
While stainless steel is a sturdy and attractive material, it is not incorruptible. Stainless steel is
susceptible to rusting. There are three basic things which can break down stainless steel’s
outer layer and allow corrosion.
1. Mechanical abrasion - those things which will scratch the steel’s surface, such as steel
pads, wire brushes and scrapers. Instead, use soft cloths or plastic scouring pads for
cleaning and brush with the polish line or “grain.
2. Water - especially hard water which can leave behind deposits. When possible use treated
water - soft water is much gentler on the stainless steel’s surface.
3. Chlorides - often found in water, food and table salt. One of the worst perpetrators of
chlorides can come from household and industrial cleaners, especially those with
quaternary salts. Never use hydrochloric acid (muriatic acid) on stainless steel. Instead,
use non-chloride cleaners. If chlorinated cleaners must be used, rinse several times and
wipe dry immediately.
