Will add a quick comment here around the “yellow”. You have to assess if the discolouration is from adhesive, from foam aging, or from sweat. Adhesive and foam aging are not worth the time or effort as you will either cause further noticeable discolouration or potentially wear out the padding.
However when it comes to yellowing from sweat and use, this will come out with extremely hot water and soap. I’ve been able to rescue VERY yellowed equipment with just soap and hot water.
If you are talking about the Jofa/RBK white foam that is covering elbow pad caps, or the material that makes up the rest of the pad, those can be cleaned with great results. If it’s something like shoulder pad caps that have a mesh type fabric with the foam padding underneath those are less likely to come “white” as the foam Color cannot be restored.
A small warning too, if you soak any of those pieces that have Velcro straps too long the adhesive between the Velcro and the leather piece may separate and lose its tackiness. Especially the made in China stuff that uses a cheaper synthetic leather piece. The made in sweden pro stock actually used a different leather material and even a different adhesive layer.
Hope this helps and if you are trying to clean something specific and want pointers I’m happy to help!
