Industrial cleaning procedure


• Safety rules must be taken into account when using cleaning machine and other electrical equipment.
• Wear appropriate particle dust mask during preparation and respirator during application.
• Wear safety bell when working overhead.
• Always read MSDS (material safety data sheet) for all chemicals before using.


Pre-cleaning, this as it implies, removes the gross contaminants before starting pure cleaning.
Rubbish such as debris, the piece of broken devices and other solids will be collected manually and bring to gathering point.
With furniture, use feather duster, towels or even vacuum to remove dust on its surface.


Fine cleaning or pure cleaning is final step of cleaning process. Care must be taken into account during this step since you may damage cleaned objects if you are careless.

1. Cleaning glass

General note
• Never combine an acid and an alkali to clean glass. One partially neutralizes the other and you waste these neutralized materials. Thus do not mix vinegar and ammonia
• Do not drip alkaline or alcohol solutions on painted or varnished woodwork as it can damage the finish.
• Do not drip cleaning solution on woodwork.
• Avoid washing windows in direct sunlight because they tend to streak and are more difficult to clean.

Cleaning procedure
• Remove spot and the other stain such as dust, paint mark, grease… on glass surface and its frame by using specialized cleaning tools with dedicated chemicals solution such as ammonia, soda, alcohol…
• To remove hard water deposits and some soils, use a weak acid such as vinegar.
• Wring out a cloth, sponge, or chamois almost dry before wiping the glass surface. Dry the wet surface with paper towels, window wipes, or a chamois. Use rubber squeegees with long handles for large or high windows. When using a squeegee, stroke from top to bottom. Wipe the squeegee after each stroke.
• For glass which has had silver electro-deposited on the surface looks particularly unappealing when dirty, using liquid or cream silver-polish on a soft cloth and rubbing vigorously.

2. Cleaning sanitation areas

• Use brush and dedicated chemical solution to remove the spot and stain on all toilet parts (wall, lavabos, toilet seats, water taps….)
• Clean other equipments such as ventilation fans, hot water heaters…
• Clean lighting system such as light bulbs, light tubes…by using a clean cotton dust mop with Waterless Cleaner.

• Cut loose pile
Loose and frail carpet pile shall be cut to prevent the loose end from getting caught in the vacuum cleaner brush or the extractor machine therefore preventing damage to the carpet and to the equipment.
• Vacuum along baseboards and corners
Use a vacuum hose with crevice tool along the edge of the carpet and in corners where the upright vacuum cannot reach. Remove dirt, sand, dust and all foreign matter. Follow up with the upright vacuum.
• Pre-treat carpets
Using a pressure sprayer with a carpet cleaning solution, spray soiled areas such as doorways and traffic lanes before extracting. For very heavy soiled doorways, follow pre-treatment with one or two passes with the extractor machine to loosen dirt for normal cleaning.
• Extract carpets
With the extractor, floor machine, go over entire carpet to clean and remove dirt, soil, grime and stains. Repeat this process as needed in order to restore carpet to a sanitary condition keeping in mind not to go over wet carpet.
