Power wash patio

Keeping your patio fresh, clean and free from moss or algae doesn’t have to be hard work, but many people ask: “Do I need to pressure wash after using patio cleaner?” The answer depends on how dirty your paving is and which product you’re using.

In this guide, we’ll explain exactly when you do (and don’t) need to pressure wash after using a patio cleaner like Joint-It So Clean or Joint-It Algae Remover, so you get a beautiful, slip-free patio all year round.

When Do I Need to Pressure Wash After Using Patio Cleaner?

If you’re wondering, “Do I need to pressure wash after using patio cleaner for heavy dirt?”, the answer is yes for very dirty patios.

For paving with lots of moss, green algae, black spots, or deep-seated grime, the best results come from using Joint-It So Clean or Joint-It Algae Remover first, then pressure washing. Here’s how:


Apply the Patio Cleaner First:

Spray or pour Joint-It So Clean onto the surface to loosen dirt and algae. This makes the grime easier to lift off.

Leave It to Work:
Allow the patio cleaner to work for the time recommended on the label. This gives the active ingredients time to break down stubborn build-up.

Pressure Wash for a Deep Clean:
After the product has soaked in, use a power washer to blast away the loosened debris. This restores your patio to its best condition.

Reapply for Extra Protection:
If your patio is very dirty, you can reapply Joint-It So Clean or Joint-It Algae Remover after pressure washing to help prevent future moss and algae growth.
