RESIDENTIAL CLEANING TIPS
1. Setting Up Workspace
Place sheets or rags under the ladder when setting it up to avoid damaging floors or furniture. This protects your customers’ floors and furniture from getting scratched or damaged by the ladder feet.
2. Removing Registers
When removing registers, keep pressure on them so they don’t fall, and score around them to break paint or caulk seals. Registers can fall suddenly when released if you don’t hold them. Scoring breaks the seal so you don’t damage the surrounding drywall.
3. Marking Register Locations
Mark the location and position of each register before removing to ensure proper reinstallation. This allows you to put them back exactly as they were for proper airflow and aesthetics.
4. Setting Up Pogo Poles
Use pogo poles properly – mark ceiling height first, lock pin in place, keep vertical and tight to ceiling. Marking ceiling height ensures you cut the pole to the right size. Locking the pin and keeping it tight prevents shifting while working.
5. Use the Push/Pull Technique
Use the push/pull technique with air hoses and brushes, medium speed, and reverse direction regularly to effectively clean ducts. This agitates debris for better cleaning. High speeds can damage ducts. Reversing helps clean all sides.
6. Deflector Bags
Deflector bags in duct vacuums protect from punctures – install properly. The deflector prevents debris from tearing the bag. Dual circuits prevent tripping breakers.
7. Dryer Vent Clip
Attach dryer vent clip before cleaning to hold flap open for suction. Check airflow after by turning dryer on briefly. The clip enables airflow needed for cleaning. Checking it ensures the dryer vents properly after cleaning.
8. Cutting Duct Board
Cut duct board access holes at 40-45 degree angles like a pumpkin top. Replace cutouts after cleaning. This creates flaps that fit back into place neatly when replaced.
8. Replacing/Installing UVC Lights
Use gloves when handling UV light bulbs. Mount securely and plug into 110/120V outlet. Oils from skin can damage bulbs. Secure mounting prevents issues. Use proper voltage.
