grease/stains on painted walls

[bebemoojem]

...washed and sanded a little and repainted and repainted and repainted and they're still there :( What is my next course of action?

I wanted everything to look all fresh and clean before dh was home this evening (and to see if he noticed ) but as it stands it won't really be any different

Are they newly painted? I had what looked to be rust spots on my ceiling after it was replastered and no amount of paint/sanding would cover them. After googling I discovered they might be silicone and the advice was to use a solvent and then paint over that. The solvent I used came in an aerosol can and it worked a treat. Can't remember what it was called but local decorator trade centre should be able to help.

They were fresh painted (newbuild) walls when they became marked. The grease I think is spatters off dh and his cycling kit...tho why they are where they are I do not know. The stain is from one of his dripping camelbak bags which went unnoticed in the downstairs cloakroom/wc until I smelled a strange smell days later...
I tried using washing up liquid and degreaser and various other products to remove the marks but they stayed on the original paint/wall so I thought I could paint over them...but the marks have come through even using a darker color and having 3 coats on that particular wall

hmm just had a thought, if I painted glossy/semi-glossy over the spots and then painted over that with the emulsion would that work? or would I then have weird spots on the wall??? wonder which/what would be more desirable

and i have more time than I thought because his trains been cancelled...

to remove grease, clean off with white spirit.

If it is a fashionable expensive flat emulsion it may be more absorbent than a paint to 1970's or later formula.

You can get white "stain blocker" at paint shops. Gloss paint will change the texture of the patches.

right so I'll need the stain blocker as the white spirit was one of the things I tried and it didn't work
so I'll not finish it tonight. Ah well feet up.
Thanks
