How to clean BBQ grill grates
Updated: 23 October 2026
The bars are still hot enough that last night’s sauce is soft. How to clean BBQ grill grates at that moment is a sequence, not a ranking of brushes. Heat, crumpled foil, a wire brush, a steam head, and a cold soak are different jobs, and mixing their safety lines is how people get hurt or leave the grate half done. This page is that sequence for a gas or charcoal barbecue at home. The eleven brushes and their prices are on our [grill brush comparison](/hub/grill-accessories/grill-brush). There is no lab test. A qualifying purchase can earn us a commission at no extra cost to you.

Use the heat you already have
Clean while the residue is still soft. BBC Good Food uses oven gloves and crumpled aluminium foil on a hot grate, and does not recommend a wire brush because steel splinters can be swallowed. Weber’s UK page for porcelain-enamelled grates says to preheat and then use a stainless steel grill brush. A hot burn-off softens stuck food. It does not sterilise the grate. The Food Standards Agency says to clean the barbecue, follow the manufacturer, and keep raw-meat tools off ready-to-eat food. A brush that scraped raw chicken is not a salad tong. Which head to buy is on the grill brush buying guide.
If the brush is wire, look twice
Weber’s UK brush page says to examine the brush before each use, discard it if bristles are loose or broken, and check the grate before food goes on. A broken bristle can cause serious internal injury. Replace the brush at least every season. Hold the head over a bin and pull at the wires with a gloved finger before you brush. Afterwards, look along the bars for anything that shines and is not food. If you find a loose wire, throw the brush away and check again before anyone eats. The Food Standards Agency does not ban wire brushes. What to do if a sharp piece may have been swallowed is on wire or bristle-free grill brush. Leave the brush dry. One Grill Guard review says the inner part rusted quickly.
A steam head is a different sequence
A steam brush is not the wire method run hotter. Pietuley, at £17.99, tells you to preheat above 204°C, turn the burners off, and dip the head so steam lifts grease. The listing claims a scraper and a replaceable head that is dishwasher safe. The dimension line is 10 x 8 x 2 cm. Only two UK reviews are in the file. Do not run that dip with the gas still on. Do not soak a cordless motor because a different listing says waterproof. If the head is spinning, two of the three motors in this set are described as stopping when you press, and pressing harder is the wrong response. Foil stays in the glove. Wire gets the bristle check. Steam gets the burners-off dip.
Soak what the hot pass missed
When the crust is old, take the cold grates off and soak them. BBC Good Food’s deep clean is a soak, then a soft nylon brush, not more wire on dry carbon. Soapy water is the ordinary soak. Vinegar and bicarbonate of soda is the version for stubborn grease. Rinse and dry, and oil only if the grate is not non-stick and the maker allows it. On gas, disconnect the cylinder first. This page does not tell you how to strip a hose. If you smell gas, stop. A burner that will not shut off needs a gas engineer. Charcoal gets the same soak once the coals are cold. Fat in the tray and blocked burner ports are not a bristle job. A cracked grate is a replacement, not a harder scrub.
Common questions
What can I use if I will not use a wire brush?
Use crumpled aluminium foil and oven gloves on a hot grate, as BBC Good Food describes, or a non-shedding head such as the coiled brush that guide names. In this set, Pietuley’s steam head is the bristle-free manual option, with burners off. Half an onion or a wooden scraper in tongs is the Weber help-centre alternative. You still look at the bars before food goes on.
How do I deep-clean a grate that lives outdoors?
Take the cold grates off, soak them in soapy water or in vinegar and bicarbonate, then use a soft nylon brush on what remains. Dry them before they go back. On gas, disconnect the cylinder first. Do not leave the brush in the rain afterwards. A Grill Guard review describes rust on the inner part after the tool was not kept dry.
When do I throw the brush away?
Throw it away when a bristle is loose or broken, when the handle has cracked or will not lock, or when the head has rusted through. Weber UK also says to replace a grill brush at least every season even if it still looks tidy. A large amazon.co.uk review count does not extend that season for you.
Can I run a steam brush with the gas still on?
Not on the Pietuley instruction in this file. Heat the grill above 204°C, turn the burners off, then dip the head. Leaving the gas on during the dip is a different and riskier setup than the listing describes. That sequence is for this steam type, not for every wire brush.
Does a hot burn-off mean the grate is sterile?
No. Heat softens grease and kills some germs on the surface. It is not a sterilising cycle and it is not a substitute for keeping raw meat off ready-to-eat tools. The Food Standards Agency still wants you to clean the barbecue and follow the manufacturer. Look for anything the brush left behind after the burn-off.
