While plexiglass is a dependable, resilient alternative to traditional glass, plexiglass sheets should be polished in a slightly different fashion than their glass counterparts. Below are the best tips for making your plexiglass sheets shine like new.
When polishing plexiglass sheets, it is important that you steer clear of commercial glass cleaners. The vast majority of these cleaners feature ammonia as an active ingredient and, while it can effectively lay waste to caked-on dirt, it can also dull plexiglass surfaces. So, when shopping for cleaning supplies, make a point of purchasing cleaners designed specifically for plexiglass.
Alternatively, if you're not a fan of the potent chemicals found in most commercial cleaners, you create your own highly effective cleaning solution. Inside of an empty spray bottle, combine equal parts of hot water and white wine vinegar. In addition to making your plexiglass sparkle, this solution is effective in removing mold and mildew deposits.
2. Give Your Plexiglass a Preparatory Wiping
Before proceeding to polish your plexiglass sheets, you'll need to give them a preliminary wiping to remove any large caked-on dirt deposits. With the aid of a dampened sponge, washcloth, or paper towel, vigorously wipe the plexiglass in a circular motion, starting at the bottom of the sheets and working your way up. Keep in mind that the more dirt and debris you remove while carrying out this wiping, the easier your plexiglass will be to polish. Also, failure to remove large deposits of filth is liable to present problems during the polishing process. After removing as much filth as possible, you'll be ready to begin polishing your plexiglass.
3. Use a Sponge
Once you've carried out your preliminary cleaning, you'll be ready to begin polishing your plexiglass sheets. Start the polishing process by thoroughly spraying the sheets with your plexiglass cleaning solution, taking care to apply it to every area of the plexiglass. Next, use a sponge to vigorously polish the plexiglass in a circular fashion, starting at the bottom and gradually working your way to the top. You may need to repeat this process several times before the plexiglass is fully polished. Before proceeding to dry the plexiglass, spray the freshly polished sheets with warm water. This will help rinse off your cleaning solution.
4. Follow Up with a Squeegee
After successfully polishing your plexiglass, you'll need to dry it with a squeegee in order to ensure that it remains free of streaks. When drying off your plexiglass, make sure to apply a fair amount of pressure as you run the squeegee across your plexiglass in a top-to-bottom fashion. If you don't have a squeegee on hand, folded sheets of some newspaper have been known to make good streak-free drying tools. Once every last trace of water and cleaning solution has been removed, the polishing process will be complete. To keep your plexiglass in prime condition, it is generally recommended that you polish it at least once every other month.
