Brightening up a Garden Retaining Wall All manner of questions and solutions to problems and issues surrounding the subject of brickwork, blockwork and stonework

I've got a garden retaining wall made with the same bricks as the house multi buff colour I think. But the wall is looking dull and lost its colour. I've tried pressure washing it then used a brick acid but still looks same. Thought about using a colour enhancer or a wet look sealer but unsure what to do next ? Any ideas please ?
