When I spotted Elbow Grease Glass Cleaner on the shelf for just £1, I had to wonder what corners were being cut. A 500ml bottle of window cleaner for less than the price of a Freddo? Either this is the bargain of the century or there's something fishy going on. I've spent years watching people spend £3-5 on branded glass cleaners, only to moan about streaks and residue afterwards. The Elbow Grease formula promises vinegar-powered cleaning that tackles grease, grime, and fingerprints whilst delivering that holy grail of window cleaning: a streak-free finish. At this price point, it's almost too cheap to trust, but sometimes the simplest solutions work best.
Vinegar has been cleaning windows since your gran's gran was scrubbing sash windows in Victorian terraces. The acetic acid cuts through mineral deposits and soap scum whilst evaporating cleanly - which is why professional window cleaners often add it to their solutions. Elbow Grease has built their formula around this principle, and frankly, it's a smart move for a budget product.
The 500ml bottle feels substantial enough for regular household use. I've found that most people go through glass cleaner faster than they expect, especially if you're tackling patio doors or multiple mirrors. At £1, you could buy three bottles and still spend less than one branded alternative.
The product claims to work on windows, mirrors, glass tables, and drinking glasses. I've tested similar vinegar-based cleaners and they generally deliver on this promise, though some surfaces respond better than others. Glass tables and mirrors tend to show the best results - the vinegar cuts through fingerprints and water marks effectively.

Windows are where things get trickier. External windows with built-up grime and weather deposits need more elbow grease (pun intended) than internal surfaces. The formula should handle light to moderate dirt, but if your windows haven't been cleaned since the last royal wedding, you might need multiple applications.
This is where budget glass cleaners often fall flat. Streak-free cleaning depends as much on technique as formula - you need the right cloth, proper wiping patterns, and ideal conditions. The vinegar base gives this product a fighting chance, as vinegar naturally evaporates without leaving residue when used correctly.
However, I've noticed that cheaper glass cleaners sometimes contain more water and fewer surfactants than premium brands. This can mean more buffing is required to achieve that perfect finish. At £1, I wouldn't expect the same performance as a £4 bottle, but it should still do the job with proper technique.
The biggest limitation is likely the concentration. Budget products often stretch their active ingredients thinner, which means you might need to use more product per cleaning session. The packaging doesn't specify the vinegar concentration, which is telling - premium brands usually shout about their formulation strength.

There's also no mention of additional cleaning agents beyond vinegar. While vinegar is excellent for mineral deposits and light grime, stubborn grease and organic deposits might require stronger surfactants. This could be an issue for kitchen windows near cooking areas.
Elbow Grease offers this cleaner in pack sizes up to 12 bottles, which suggests they're targeting bulk buyers and trade customers. At £1 per 500ml bottle, you're paying 0.2p per ml. Compare that to branded alternatives at 1-2p per ml, and the value proposition becomes clear.
For households that clean windows monthly, a single bottle should last 2-3 months. Even if you need to use 50% more product to achieve the same results as a premium cleaner, you're still saving significant money.
At £1, this is worth trying even if you're sceptical about budget cleaners. The vinegar base gives it credibility, and the price means there's little risk if it doesn't meet expectations. Perfect for rental properties, student accommodation, or anyone who cleans windows frequently enough to appreciate the cost savings.
