That's a common and frustrating problem! Those unsightly black marks are usually caused by the bin's plastic wheels or base rubbing against the pavement, especially in hot weather. The heat softens the plastic, causing it to transfer onto the concrete or asphalt. Don't worry, there are several simple and effective solutions.
First, to remove the existing black marks, you can try a few methods. A simple paste of baking soda and water, scrubbed with a stiff brush, often works wonders. For tougher stains, a commercial concrete cleaner or a degreaser is very effective. Always test any cleaner on a small, inconspicuous area first.
Now, to prevent the marks from coming back, here are your best strategies:
1. Create a Barrier: The simplest solution is to place a barrier where you keep your bin. A small outdoor mat, a piece of plywood, or even a few patio pavers can create a protective layer between the bin and your pavement.
2. Upgrade the Wheels: If your bin has hard plastic wheels, consider upgrading them. You can find replacement wheels with softer, non-marking rubber treads online or at hardware stores. This is a more permanent fix.
3. Regular Cleaning: Keep the bottom of your trash bin and its wheels clean. Regularly hose off any dirt, grime, or plastic residue that has built up. A clean bin is less likely to leave marks.
4. Relocate the Bin: If possible, try moving the bin to a different spot on the pavement occasionally. This prevents continuous pressure and friction on the same area.
By using one or a combination of these tips, you can keep your pavement looking clean and mark-free all year round.
