What Kind of Stain Do You Have?

Before you start scrubbing, find out what stain you’re dealing with. Different stains need different cleaning methods. In Vancouver, you often see these stains on concrete:

• Green Stains: These look dark. They come from leaves, berries, mold, and algae. Wet Vancouver weather makes these very common.
• Oil and Grease: These are tough marks. They come from car leaks, BBQ spills, or dropped food. They soak into the concrete.
• Rust: These are reddish-brown marks. They come from metal furniture, garden tools, or old metal inside the concrete.
• White Powder: This looks like white dust. It happens when water dries on the concrete. It leaves salt behind. It’s not a true “stain” but it looks bad.
• Paint and Chemicals: These are from spilled paint or household cleaners.

Knowing the stain helps you pick the right concrete cleaner. This keeps your concrete patio door safe and looking good.

Tools You’ll Need for Patio Cleaning

Having the right tools makes cleaning easier. Here’s what you’ll likely need:

1. Stiff brush: Good for scrubbing stains.
2. Buckets: For mixing cleaners and rinsing.
3. Hose or pressure washer: For rinsing well. A pressure washer is great for general cleaning. Be careful with it on stained spots. Don’t harm the concrete. 
4. Gloves and eye protection: Always wear these. Stay safe with chemicals.
5. Mild soap: Dish soap or laundry soap works for many common stains.
6. Special cleaners: You’ll need special cleaners for oil, rust, or algae. Make sure they are for concrete surfaces.
7. Clean cloths: For blotting fresh spills.

How to Clean Common Patio Stains

Once you know your stain and have your tools, it’s time to work. Always test any cleaner in a hidden spot first. Make sure it doesn’t change your concrete’s color or harm it.

Getting Rid of Green Stains (Moss, Algae, Mold)

Green stains are very common in Vancouver. This is due to rain and mild weather. For these, scrubbing and a special cleaner work best.

• Get Ready: First, clear away loose leaves or dirt from the stain.
• Make the Cleaner: Mix 1 part household bleach with 3 parts water. You can also buy cleaners for moss and algae on concrete. For a safer option, try strong vinegar.
• Apply: Pour the cleaner over the stain. Let it sit for 15-30 minutes. This helps it break down the growth.
• Scrub and Rinse: Scrub hard with a stiff brush. You’ll see the green or black stuff lift away. Rinse well with a hose or pressure washer. Do it again if needed.

Removing Oil and Grease Stains

Oil and grease stains need a different plan. They soak deep into the concrete.

• Act Fast: For new spills, blot up as much oil as you can. Use cloths or cat litter. Do not rub, or you’ll spread it.
• Use a Degreaser: For older stains, use a concrete degreaser from a store. Follow its directions carefully. Many degreasers pull the oil out of the concrete.
• Poultice Trick: For tough stains, make a paste. Mix an absorbent powder (like cat litter) with a solvent (like mineral spirits). Put the paste over the stain. Cover it with plastic wrap. Tape the edges down. Let it sit for 12-24 hours. The paste will soak up the oil as it dries.
• Scrub and Rinse: When dry, scrape off the paste. Scrub the spot with a stiff brush and mild soap. Rinse well.

Cleaning Rust Stains

Rust stains can be very hard to remove. Do not use bleach on rust; it can make it worse.

• Rust Remover: Buy a rust remover made for concrete. These usually have special acids that dissolve rust.
• Apply: Use the rust remover as the label says. Often, you put it on, let it sit for a few minutes, then scrub.
• Rinse Very Well: Rinse the area completely. Get rid of all the rust remover. These chemicals can be strong. You might need to rinse many times.

Fixing White Powder (Efflorescence)

This white powder happens naturally. But it doesn’t look good.

• Dry Brush: Often, you can just brush it off with a stiff, dry brush.
• Acid Cleaner (Carefully!): For tougher white powder, you can use a very weak mix of muriatic acid. But be super careful! Wear safety gear. Mix very little acid with a lot of water (1 part acid to 10 parts water). Put it on a wet surface. Rinse right away after scrubbing. It’s often best to let a pro handle acid cleaning.
