Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to remove varnish [title] Create good ventilation. [step] Whether your sanding or using a chemical solvent, it's a good idea to have ventilation. Open windows and use fans to create cross-ventilation if you're inside.

Ending1: If you live in a hot environment, use spritz or vapor freshener. Open-ventilation works best when it's at a temperature around 100 degrees f (104 degrees c). Ending2: [title] Remove all the pieces of varnish (red, black, and a white). [step] This is absolutely necessary, but how you do it will depend upon how closely you were able to put each piece in its proper place over time. Ending3: [title] Clear away the painter's tape. [step] Before getting any sanding work done, clear away any materials the varnish would have damaged. Ending4: If you can, take the piece outside or in a well-ventilated area to work on it. [substeps] To create cross-ventilation, place one fan so it's blowing into the area, and one so it's blowing out a window.
