{"type":"firestarter.listing","listing":{"id":"lst_Q5hqvjMT","product_name":"Hjul Wheel Cleaner","category":"Chemicals","description":"You may have seen color change wheel cleaners before, but Hjul is different.\nIt’s a thicker recipe for a bit more dwell time and contains soap to remove general road grime, as well as the active ingredient that removes ferrous brake debris. But it also has some solvent content to soften tar spots – those little black dots that often pretend to be stubborn brake dust deposits.\nIt’s pH neutral too, so you can use it with some of the more sensitive wheel materials and finishes (but always rinse it thoroughly after use).\nTry the others, then settle on Hjul. It’s that good.","images":["https://cdn.shopify.com/s/files/1/0520/2047/8135/products/stjarnagloss-hjul-500ml-front-web.jpg?v=1762198324","https://cdn.shopify.com/s/files/1/0520/2047/8135/products/stjarnagloss-hjul-500ml-back-web.jpg?v=1672770943","https://cdn.shopify.com/s/files/1/0520/2047/8135/products/stjarnagloss-hjul-500ml-description-web.jpg?v=1672770943","https://cdn.shopify.com/s/files/1/0520/2047/8135/products/stjarnagloss-hjul-1L-front-web.jpg?v=1693433958","https://cdn.shopify.com/s/files/1/0520/2047/8135/products/stjarnagloss-hjul-1L-description-web.jpg?v=1693433958","https://cdn.shopify.com/s/files/1/0520/2047/8135/products/stjarnagloss-hjul-1L-back-web.jpg?v=1693433958","https://cdn.shopify.com/s/files/1/0520/2047/8135/products/stjarnagloss-hjul-5L-front-web.jpg?v=1693433958","https://cdn.shopify.com/s/files/1/0520/2047/8135/products/DSC02324-web.jpg?v=1672770943","https://cdn.shopify.com/s/files/1/0520/2047/8135/products/DSC02488-web.jpg?v=1672770943","https://cdn.shopify.com/s/files/1/0520/2047/8135/files/stjarnagloss-hjul-500ml-front-12case-web.jpg?v=1780685999","https://cdn.shopify.com/s/files/1/0520/2047/8135/files/stjarnagloss-hjul-1L-front-12case-web.jpg?v=1780686578","https://cdn.shopify.com/s/files/1/0520/2047/8135/files/SG-Hjul-5L-Caseof4_7b052c8d-f388-4211-a643-8401b64deabe.gif?v=1780686597"],"price":8.5,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:57:11.691Z"},"share_url":"https://firestarter.network/l/lst_Q5hqvjMT","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
