Where possible we like to include a “home recipe” cleaner in our tests. For this test we used one-part white vinegar and one-part water.
While it didn’t clean well enough to be recommended or worth considering, it did perform better than many other branded cleaners. Because white vinegar is often already in most households, it can be a handy alternative. If you’re not fond of the vinegar smell, you can try adding a fragrance, such as lemon, to the mixture.
