@suzanabhattarai hi Suzan, I've seen @prettyliving use diggers wall cleanup on her instagram posts. It seems to work a treat.
Hi @suzanabhattarai,
Thank you for your question and welcome to the Bunnings Workshop community.If you were aware of what the red marks are, there may be a more specific product, however, the DIGGERS 500ml Wall Cleanup that @projectmumdanni has suggested would likely be a great solution.
Let me know if you have any further questions.
Jacob
