I'm trying to upload photos but can't seem to - does anyone know why this is happening?

Apparently many people have trouble uploading photos. Just try uploading again within a comment.

Here are some photos. Had to take a screen shot to get the correct photo upload format.

Hi all, can anyone please advise? Thank you

I do think that a Minwax gel stain would work well, but agree that you probably won't like the result if you only use it on the discolored areas.... you may need to do full coverage on all of it to have a better match. Minwax seems to have changed their gel stain colors, but what you show looks like what they called 'java', iirc. Is there anywhere inside a cabinet door that you can experiment?

I'm renting this flat, so not sure who the manufacturer is. Thanks for the Miniwax suggestion. Do you think the following would work just as well or should I use gel stain to be specific. I have no knowledge of woodworking at all: https://www.homedepot.com/p/Varathane-1-qt-Espresso-Classic-Wood-Interior-Stain-339719/305501997?cm_sp=BazVoice--QA_PQRDR--305501997-_-x

I don't mind staining all the cabinets if that works. Thank you again.

Stain is thin and soaks into the wood. Gel stain is thick and does not soak in. They work differently and I think will give you a different result. Without knowing what the cabinets are coated with now, or how much of the finish you've removed, it's hard to guess your result. But since you already said you don't want to sand, I'd guess that gel stain might work better for you.

eta: your coconut oil based product may cause a problem with adherence of anything you try to apply now.

I would leave them alone. Just make sure they are clean. Since this is a rental, if what you try doesnt work out well, you have just made things worse, and that may anger your landlord. Let them decide, once you decide to move, since they probably know where they were purchased from, and the brand of cabinets, and the exact color. How did you get oil spots all over that you needed to rub that hard. I have never had oil on a cabinet. Food spills, yes, but, never oil. In any case, it may not even be your fault, it may be a defect in the cabinet finish itself. Best to leave for landlords to deal with.

Absolutely zero wood grain showing in the photos. So I'm 99.99999% certain that the cabinets are not stained.

Could be paint, colored lacquer, thermofoil, even laminate.
