A solar pool cover is one of the most efficient ways to heat your swimming pool naturally, reduce water evaporation, and lower chemical consumption. But like all swimming pool equipment, it requires regular maintenance to stay effective. In this guide, we’ll show you exactly how to clean and care for your solar pool cover, when to replace it, and how to properly store it—ensuring it lasts for years.
Why Clean Your Solar Pool Cover Regularly?
South African pool owners often invest in solar pool covers to maintain water temperature and reduce costs. However, chlorine buildup, algae, and dirt particles can shorten the life of your cover if not cleaned properly.
By regularly cleaning your solar blanket, you will:
- Prolong the lifespan of the cover (up to 5–7 years)
- Improve pool heating efficiency
- Reduce chemical degradation
- Prevent the growth of mould and mildew during storage
Step-by-Step Guide: How to Clean Your Solar Pool Cover
Cleaning your pool cover is simple and can be done with basic household items. Here’s how:
Supplies You’ll Need:
- Soft brush or broom
- Garden hose
- Mild dish soap
- Bucket
- Rubber gloves
Step 1: Rinse Off Surface Debris
Unroll the solar blanket on a flat surface (grass or poolside paving works well). Use a garden hose to rinse off leaves, dust, and chlorine residue. This step also helps you identify tough stains or algae buildup.
Step 2: Make a Soap Solution
Fill a bucket with clean water and add a small amount of mild dishwashing liquid. Avoid harsh chemicals, as they can damage the plastic material and reduce UV resistance.
Step 3: Scrub Gently
Using a soft brush or broom, gently scrub the surface of the cover with the soap solution. Pay extra attention to areas with algae or oily residue. If needed, use gloves and apply a bit of elbow grease to lift stubborn dirt.
Step 4: Rinse Thoroughly
Once you’ve scrubbed the entire surface, rinse it off again with the garden hose to remove any remaining soap and debris.
Step 5: Let It Dry Completely
Before folding or storing the solar cover, make sure it is 100% dry. This prevents mould growth and material breakdown.
How to Store a Solar Pool Cover Properly
When pool season ends or you won’t be using the cover for a while:
- Fold the cover into manageable sections
- Roll it up tightly
- Store it upright in a dry, shaded space (garage, pool shed, or covered patio)
Never store it wet, as this leads to mould and foul smells when you open it again.
How Often Should You Clean a Solar Pool Cover?
We recommend cleaning your solar pool cover every 3–6 months, or more frequently if:
- You use the pool daily
- You live in a windy or dusty area like Cape Town, Bellville, or Durbanville
- You notice chemical build-up, algae, or foul odours
Regular maintenance reduces long-term costs and delays replacement.
When Should You Replace Your Solar Cover?
Your solar blanket won’t last forever. Here are signs it’s time for a new one:
- Bubbles are falling off
- Plastic feels brittle or cracks easily
- Cover is discoloured or smells unpleasant
- Heating efficiency drops significantly
Typically, high-quality solar covers last 4–7 years with proper care. Cheaper models may only survive one or two pool seasons.

How Long Can You Leave a Solar Cover On?
You can leave your solar cover on as long as your pool chemistry is balanced. In fact:
- Longer coverage = better heat retention
- Night-time coverage prevents heat loss
- However, extended exposure to harsh chemicals shortens the life of the cover
Let your pool “breathe” occasionally to reduce chemical saturation and material stress.
Pools Reno Tip: Use a Pool Cover Roller
If you’re constantly removing and replacing your solar cover, invest in a pool cover roller. It reduces strain, prevents tearing, and makes handling easier. We supply and install rollers throughout Cape Town and surrounding areas.

FAQ: Solar Pool Cover Cleaning & Maintenance
How often should I clean my solar pool cover?
Clean your solar cover every 3 to 6 months or whenever it becomes visibly dirty or affected by chlorine buildup.
Can I use high-pressure washers to clean it?
No. High-pressure jets can damage the plastic bubbles. Always use a garden hose and soft brush.
Is it OK to store the cover in direct sunlight?
It’s better to store it in a cool, shaded area. Prolonged exposure to UV when not in use will cause the material to degrade faster.

Yes—if your pool’s chemical balance isn’t maintained. Always ensure proper sanitation when the cover is on.
