When stripping floors no matter how careful you are, there is always a possibility of splashing the solutions onto a wall,door, appliance and so on. If left on a surface the solutions can cause damage. Always carry a damp towel or have one very handy that you or an extra employee can wipe any splashes off immediately. If there is painted trim around floors then there is no way to protect it and there is a good chance that some paint will come off. Tell the client before you strip that this may happen and they will be responsible to repaint if needed. If there is a possibility of client being around the job site , then always carry a clean white towel. Nothing says clean better than clean. A dirty towel can send the wrong message. If someone was wiping a splash off your refrig then which would you rather see? A nice pretty white towel or an extremly dark, dirty , ragged towel? Both could do the job but one is desired more than the other.
