To revive a sluggish sourdough starter, pour off most of the dark liquid (hooch), discard most of the old starter, then feed the remainder with equal parts flour and water (e.g., 50g starter, 50g flour, 50g water) in a clean jar, ideally using warm water and flour to encourage activity; repeat this feeding every 12-24 hours until it consistently doubles in size, indicating it's strong enough to bake with again, often taking 1-3 days.
Feed with flour and water
Feed the 113g saved starter with equal parts (by weight) unbleached all-purpose flour (56g) and water (56g). Usually, you'd feed with cool or room temperature water. But since your starter has been in the fridge, warm (not hot) tap water will help get things going.
How To Start a Car with a Bad Starter (Temporarily)
Scoop out 30g of that starter into a fresh, clean jar, add 30g of flour and 30g of water. Stir it up and keep it warm. Your starter will likely recover in a day or two. Do not discard and refeed until the starter is completely covered with bubbles on top.
This recipe recommends using bottled water to feed your starter, rather than tap water. The reason: Unfiltered tap water often contains at least tiny amounts of chlorine, which can harm the yeast and bacteria that make your starter active.
Symptoms of a bad starter include a single loud click, rapid clicking, slow cranking, grinding noises, or nothing at all when you turn the key, even if lights work; this often happens intermittently, especially when the engine is warm, and can be distinguished from a weak battery if the car still won't start after a jump-start. A burning smell or smoke from under the hood can also occur, and sometimes you might hear the starter spinning (whirring/whizzing) without the engine turning over.
If a little moisture gets in the housing and rusts up the brushes and brush holders, or the brushes are nearly worn out, gently rapping on the starter housing can sometimes free them up, letting them make enough contact to make the starter work.
Use Sparingly: A short, controlled spray is less likely to introduce excessive chemicals into the engine or create flooding risks. Provide Ample Ventilation: Ensure the area is well-ventilated to dissipate fumes and reduce fire risk.
Having a starter problem that only happens intermittently can be a frustrating and anxiety-inducing event. This also makes it trickier to fix. Dirty or loose wiring could be behind your problem. An electrical component like a damaged relay could cause it to fail and work under different conditions.
If the starter engages but does not disengage when you let go of the key, the solenoid is likely bad and the starter may suffer significant damage as a result. Sometimes your car starts, sometimes it doesn't. Intermittent operation can be a sign of a failing starter solenoid.
Press the Lock button on your remote car starter. Within five seconds of turning it on, turn your key back to the “off” position (or press the start button again). Repeat the on-off cycle three more times—you'll do four in total.
Once it develops mold, which is anything like green spots, pink, orange, anything fuzzy, anything that resembles mold, sourdough starter's dead, you gotta toss it. Even if you see a thick, dark layer of fluid on top of your starter.
This includes here at Breadtopia, where we recommend people use filtered tap water, bottled spring water, mineral water, sparkling mineral water, or for just the first couple of feeds: pineapple juice or water mixed with a little lemon juice.
Yes, assuming your starter solenoid is going bad, this is the short term fix. Tapping on the starter usually doesn't make the starter work if the solenoid is bad (think Nippondenso). OTOH, a starter with a bad armature segment responds well to tapping or banging with a hammer.
Grinding noises, like metal chewing on metal, often indicate that the starter's gears aren't engaging properly with the flywheel. A single, loud click usually indicates a faulty starter solenoid responsible for engaging the starter.
Yes, you can by using a portable jump starter or a battery charger. What safety precautions should I take when jump-starting my car alone? Wear safety gloves and goggles, and follow proper procedures to avoid sparks and potential battery acid exposure.
Best Tips for Reviving Sourdough Starter
Signs & Symptoms of a Bad Alternator
As long as that alternator is creating electricity and the battery is good, your car should start and stay running. If the vehicle won't crank or start but the headlights are still working, look to problems with the starter or other parts of the engine.
Jumper Cables for a Dead Battery. Nothing can jumpstart a car faster than a set of jumper cables. These cables are inexpensive (around $20), easy to use, and with a little help from another vehicle, they can get you back on the road quickly.
Dirty Motor
Grime, dust, and small metal fragments can cause damage to the electrical system between the battery and the starter. This restriction of power can lead to starter failure.
