The formation of a heterogeneous oxidized layer, also called scale, on metallic surfaces is widely recognized as a rapid manufacturing event for metals and their alloys. Partial or total removal of the scale represents a mandatory integrated step for the industrial fabrication processes of medical devices. For biodegradable metals, acid pickling has already been reported as a preliminary surface preparation given further processes, such as electropolishing. Unfortunately, biodegradable medical prototypes presented discrepancies concerning acid pickling studies based on samples with less complex geometry (e.g., non-uniform scale removal and rougher surface). Indeed, this translational knowledge lacks a detailed investigation on this process, deep characterization of treated surfaces properties, as well as a comprehensive discussion of the involved mechanisms. In this study, the effects of different acidic media (HCl, HNO 3 , H 3 PO 4 , CH 3 COOH, H 2 SO 4 and HF), maintained at different temperatures (21 and 60 °C) for various exposition time (15–240 s), on the chemical composition and surface properties of a Fe–13Mn-1.2C biodegradable alloy were investigated. Changes in mass loss, morphology and wettability evidenced the combined effect of temperature and time for all conditions. Pickling in HCl and HF solutions favor mass loss (0.03–0.1 g/cm 2 ) and effectively remove the initial scale.

“…Stainless steel is generally resistant to corrosion by AlEW due to its chromium content, which forms a passive oxide layer on the surface, providing protection (Khalid, Sulaiman, Ab Aziz, et al, 2020; Zaffora et al, 2021). However, the degree of resistance can vary depending on the grade of stainless steel and the exposure conditions (Chen et al, 2020; Costa et al, 2023). It is important to note that exposure to detergents, including AlEW, can potentially induce corrosion in these stainless steel variants.…”

“…Corrosion of stainless steel surfaces exposed to AlEW is influenced by several critical factors (Chen et al, 2020; Costa et al, 2023). The duration of exposure is a key consideration, as prolonged contact increases the risk of corrosion, potentially leading to forms like pitting or crevice corrosion.…”

“…The concentration of alkaline agents, particularly NaOH, within the AlEW solution plays a significant role, with higher concentrations elevating the corrosion risk. Temperature is another important factor, as elevated temperatures can accelerate corrosion using AlEW (Chen et al, 2020). Additionally, the surface finish of stainless steel surfaces matters; smoother, polished surfaces generally exhibit better corrosion resistance compared to rough finishes (Paknahad & Nogorani, 2020).…”

The meat industry faces significant challenges regarding removing fat, oil, and grease (FOG) residues from meat processing stainless steel surfaces, compounded by limited resources and inadequate cleaning knowledge. As an innovative solution to these difficulties, alkaline electrolyzed water (AlEW), a sustainable green degreaser, is proposed to replace the traditional alkaline wash. AlEW is produced through two–chamber (membrane) electrolysis at the cathode. AlEW with a strong reducing potential (−800 to −900 mV), high pH (10.0–11.5), and high dissolved oxygen are used to remove FOG residues from meat processing stainless steel surfaces. Our comprehensive analysis highlights the advantages of AlEW as a sustainable alternative to conventional degreasers for the meat industry, including ease of use, no storage requirements, and reduced costs for wastewater treatment. Our findings underscore AlEW's potential to improve the meat industry's quality, safety, and environmental sustainability. This review contributes to ongoing discussions about sustainable food industry solutions, aligning with the 2030 Agenda for Sustainable Development goals. In conclusion, AlEW is a promising alternative to conventional degreasers, advancing sustainability in the meat industry.Practical ApplicationsThis research introduces an innovative solution to a significant challenge in the meat processing industry—effective removal of fat, oil, and grease residues from equipment surfaces. Traditional methods involving costly and environmentally harmful chemicals have drawbacks. Our study proposes the use of alkaline electrolyzed water (AlEW) as a green degreaser. AlEW, generated by passing electric current through saltwater, exhibits high alkalinity that dissolves residues efficiently. This eco‐friendly approach not only ensures thorough cleaning but also reduces costs and addresses environmental concerns. By offering a sustainable and cost‐effective alternative, AlEW has the potential to revolutionize cleaning practices in the meat industry, enhancing food safety, operational efficiency, and sustainability. This advancement holds promise for wider adoption, benefiting both producers and consumers alike.
