BKF’s contents don’t go bad or expire when kept in a dry environment. We decided not to include an expensive lid when it is not necessary for the majority of users in order to give our customers the best value possible. A useful tip for people who might want to cover their BKF can if it’s kept in a humid environment or under the sink is to cover the top of the can with a sandwich bag (you can use a rubber band to create an airtight seal if needed).

Typically, the liquid Soft Cleanser is more than enough for routine, milder-duty cleaning. In case a deeper and more restorative cleaning is required, the BKF Cleanser powder would probably be a better option. Bottom line: They’re not intended to be identical products. By adding different amounts of water, the powder’s “strength” can be changed, making it stronger or weaker. In essence, the Soft Cleanser is “pre-diluted” or “ready-to-use” for a range of jobs (though not all of them), particularly the more commonplace cleaning duties.

Many vegetables, including rhubarb, chives, and parsley, naturally contain oxalic acid, which is an excellent rust and mineral deposit remover. The oxalic acid utilized in BKF is typically made from plant or vegetable waste and is obtained from industrial suppliers. While consuming large amounts of oxalic acid can be harmful, using BKF as directed poses no risk.

Firstly, it’s important to note that Bar Keepers Friend and Ajax are powder cleansers, which means that you can use them to clean a variety of surfaces by mixing them with water to make a paste or solution. While they both have ingredients that aid in removing stains, filth, and grime, there are some significant differences between their formulas.

For instance, Bar Keepers Friend claims to have an oxalic acid-based formula that works especially well at getting rid of rust and other stubborn stains. Additionally, the brand states that its formula is non-abrasive and won’t scratch surfaces like porcelain or stainless steel.

Initially, we tested both products on a stainless steel sink that had a significant amount of grime and grease buildup. Bar Keepers Friend left the sink spotless after slicing through the grime with little effort. On the other hand, Ajax needed a lot more work and still left some residue.

We then used a porcelain bathtub with some particularly tenacious soap scum buildup to test both products. Once more, Bar Keepers Friend triumphed, swiftly dissolving the soap residue and leaving the tub in immaculate condition. Ajax found it difficult to reduce the accumulation and needed several applications to attain outcomes that were comparable to those of Bar Keepers Friend.
