How to strip gloss from grooves in tongue and groove panels

[AdRock]

I have tongue and groove panelling to form a cupboard under the stairs.

I've just stripped off all the gloss to give me a natural wood finish but i still have white gloss in the grooves.

What is the best way to get these annoying grooves rid of the gloss? Would it be best yo use a chemical paint stripper or can i use a sanding drill bit to get in the grooves.

Also there is a rail between the panelling and ceiling/floor which still has white gloss on there. Obvisouly, a heat gun is no good there. What is the best way to strip that back?

In the end I want to paint it back white again but not with gloss because it looks horrible and where it clumps and drips, it looks horrible.

I need to do door frames too which has grooves in there and I can see where the gloss has dried in clumps

If you have tried a small wire brush by itself and that doesn't work, I'd go for a chemical stripper followed by wire wool, as a mechanical drill attachment would probably damage the wood.

In the end, if you are going to repaint, you don't need to get every last iota of paint out of the grooves, although the more you can get out the finer the finish will be.

Gloss should not clump and drip if you are a half decent decorator but I do prefer the look of satinwood myself
