The most effective way to remove old paint or varnish is by using a chemical remover. There is a huge variety of products on the market and you should research your project a little before you select a stripper. The chemical remover will soften the paint so you can scrape it off or wash it with water. Removers come in paste or liquid form. Liquid works on thin layers of paint and can usually be washed off. Paste is for trickier jobs where the paint is thick or if you have overhead work to do.
Liquid and paste remover require different type of techniques, which are listed on the back of the product. It\'s fairly easy to remove paint using the manufacturer instructions but there are key points to remember. Work on small areas so thinner doesn\'t dry.

Abrasive--"Abrading" the painted surface by manual and/or mechanical means such as scraping and sanding. Generally used for surface preparation and limited paint removal.
Thermal--Softening and raising the paint layers by applying heat followed by scraping and sanding. Generally used for total paint removal.
Chemical--Softening of the paint layers with chemical strippers followed by scraping and sanding. Generally used for total paint removal.
Liquids are primarily for clean coatings and removing one or two layers of paint. This formula dries too quickly to remove multiple layers of paint. Good for detail areas or irregular surfaces. Also good for the stubborn spots after a washable has been used.
Brushables are a thick, paste-like formula that allows the paint remover to be applied in heavy layers so that it stays wet in order to strip multiple layers (up to 10 or more) in one application. Allows remover to cling to vertical or even overhead surfaces. Some paint removers are the "wash away" or "water wash" types. These terms simply indicate that the paint remover formula includes an emulsifier that permits the chemicals to mix with water and be rinsed away with a hose.
