My woodwork is oak ... the house was built in 1925, so the woodwork has many grooves ... I tried the 3M stripper, but I cannot scrap without digging into the wood ... I have the six small window at the top and those strips are very difficult to tackle ... I have a "mouse" sander, which is the only thing that produces any result, but it is still difficult to get into tight spaces and the grooves ... Please HELP ... I am a do it your self kind of woman, but I think I have met my match.
