## 1. Routine Cleaning
### Cleaning Frequency
| Environment | Recommended Frequency |
|————-|———————-|
| Indoor warehouse | Every 6 months |
| Outdoor general | Every 3 months |
| Dusty/heavy pollution | Every 1-2 months |
| Near chemical plant | Monthly |
### Cleaning Methods
**Light cleaning (dust, dirt)**:
1. Soft brush or low-pressure water spray
2. Rinse top to bottom
3. Air dry or wipe with soft cloth
**Medium cleaning (oil, bird droppings)**:
1. Warm water (<40°C) + neutral detergent
2. Soft cloth or sponge — **no hard brushes**
3. Rinse thoroughly, zero detergent residue
**Prohibited**:
- ❌ Strong acid/alkaline cleaners
- ❌ Wire brushes, hard scrapers
- ❌ High-temperature steam (>60°C)
– ❌ Organic solvents (acetone, gasoline)

## 2. Routine Inspection Checklist
### Pre-Use Inspection (Every Time)
– [ ] Grommets: loose, deformed, rusted?
– [ ] Hemming: unraveling, cracking?
– [ ] Seams: peeling, open stitches?
– [ ] Surface: scratches, punctures?
– [ ] Color: abnormal fading (UV aging signal)?
– [ ] Mold spots?
### Monthly Inspection
– [ ] Check every grommet individually (80% of tears start at grommets)
– [ ] Large-area stretch test (brittle/hard feel?)
– [ ] Waterproof test (does water penetrate?)
– [ ] Stitching condition

## 3. Common Damage Repairs
### 3.1 Small Damage (<10cm) **Temporary repair**: 1. Special PVC tarp repair tape 2. Clean and dry the damaged area thoroughly 3. Tape should be 2-3cm larger than damage 4. Press evenly, no air bubbles **Permanent repair**: 1. Same material patch (5cm larger than damage) 2. Heat gun/HF welder for heat welding 3. Double-line stitching for reinforcement 4. Test repaired area strength ### 3.2 Edge Tears **Steps**: 1. Trim irregular edges 2. Re-hem with 5cm-wide matching edge strip 3. Heat-weld + stitch double fix 4. Punch stop-hole at tear origin ### 3.3 Grommet Detachment **Replacement steps**: 1. Remove damaged grommet 2. Inspect surrounding fabric 3. Add reinforcement patch if damaged 4. Install new grommet (stainless steel recommended) 5. Add gasket for load reinforcement ### 3.4 Large Seam Splits **Steps**: 1. Clean old seam residue 2. Roughen both sides of seam surface 3. Re-weld with HF machine 4. Double-line stitch reinforcement 5. Apply sealant for waterproofing --- ## 4. Storage Standards ### Pre-Storage Preparation 1. **Clean and dry thoroughly**: residual moisture causes mold 2. **Inspect and repair**: fix all damage before storage 3. **Anti-mold treatment**: spray fungicide in humid areas ### Folding Method **Correct folding (minimizes crease damage)**: 1. Lay flat on ground, remove sharp objects 2. Fold along fold lines (no random scrunching) 3. Fold width under 1 meter 4. Roll rather than fold (recommended for large tarps) **Prohibited**: - ❌ Folding while damp - ❌ Sharp crease angles (permanent damage) - ❌ Heavy objects on folded tarps ### Storage Environment | Requirement | Standard | |-------------|----------| | Temperature | 5-35°C | | Humidity | <70% RH | | Light | Dark storage (away from windows) | | Ventilation | Good airflow | | Pest control | Regular warehouse pest treatment | **Prohibited**: - ❌ Outdoor open stacking - ❌ Direct ground contact (use wooden pallets) - ❌ Near heat sources - ❌ Same storage as chemicals --- ## 5. Seasonal/Climate Notes ### Summer Heat - Light colors (white/gray) reflect sunlight, 10-15°C cooler - Avoid dark colors for long-term outdoor coverage - Ensure ventilation to prevent heat buildup ### Winter Cold - PVC coated fabric hardens below 0°C - Avoid folding/bending at low temperatures - Warm to 5°C+ before handling - Knife-coated and silicone fabric have better low-temp flexibility ### Rainy/High Humidity Season - Increase mold inspection frequency (weekly) - Remove mold immediately with diluted bleach (1:10) - Ensure complete dryness before folding - Use dehumidifier in storage ### Typhoon/High Wind - Reinforce all grommet fixings - Reduce grommet spacing to 0.3m - Add wind ropes and anchor points - Remove tarps before storm rather than trying to reinforce --- ## 6. Material-Specific Care | Item | PVC Coated | Knife-Coated | Silicone Coated | |------|-----------|-------------|-----------------| | Cleaning | Water + neutral detergent | Same as PVC | Avoid strong alkaline | | Repair | Heat-weld/tape/stitch | Heat-weld preferred | Professional silicone repair | | Temp range | -10°C~70°C | -20°C~80°C | -50°C~250°C | | Mold prevention | Needed | Needed (more resistant) | Naturally mold-resistant | | UV check | Every 2-3 years | Every 3-5 years | Every 5-8 years | | Folding storage | Avoid low-temp folding | Good flexibility at low temp | Best low-temp flexibility | --- ## 7. Lifespan Extension Schedule | Maintenance Measure | Lifespan Extension | |---------------------|-------------------| | Regular cleaning (every 3 months) | +20-30% | | Timely small-damage repair | +30-50% | | Proper storage (dark, dry) | +20-30% | | Regular anti-mold treatment | +15-20% | | **Full implementation of all measures** | **+50-100%** | --- ## 8. FAQ Quick Reference **Q: Tarp has become stiff?** A: PVC plasticizer migration — irreversible aging. Prevention: avoid high heat and chemical solvents. Switch to knife-coated or silicone fabric. **Q: Mold stains won't wash off?** A: Use diluted bleach (1:10), rinse thoroughly. If mold penetrated fibers, replacement recommended. **Q: Can repairs restore original strength?** A: Heat-weld repair recovers 80-90%, tape repair recovers 50-60%. **Q: How long do tarps last?** A: PVC coated 2-3 years, knife-coated 3-5 years, silicone coated 5-8 years.
