Most quality dodger glass these days is Strataglass or similar. PLEASE DO NOT use Pledge or any other product not specifically designed to be safe with optically treated dodger glass. If your windows are Strataglass use ONLY Imar cleaning products. If they are not Strataglass still use Imar it is worth every penny.

You really need to know what type of windows they are first. Are they a thicker .40 mil type of window or standard, inexpensive type windows. The thicker, high quality, windows are a "coated" glass for optimal optical clarity.
Use of products other than Imar or what is recommended WILL RUIN this thin surface coating! If they are Strataglass, or any of the other low distortion coated glass,DO NOT use any of the products mentioned below as you WILL ruin them. My very good friend owns marine canvas business and I can't even begin to tell you how many windows Seth has replaced due to people using Pledge, 303 Aerospace Protectant, Armorall, Rain X, or "gulp" Brasso, yes one customer insisted a "guy on the dock" said it was the best!
Barr none Imar makes the best treatments, waxes, and polishes specifically for the "high quality" windows. Strataglass used to sell their OWN product they now only recomend Imar because it is far superior to even thier own product that they actually made a profit on.
While Plexus makes some fine products, as does Meguiar's, these products are still NOT recommended for Strataglass and should NOT be used on high quality optically treated dodger windows. Even on the cheap windows the Imar products work far better than any of the other available treatments such as 210.
Please research what you have for glass and then decide what is the appropriate treatment.Strataglass has NO ownership in Imar just like Glen Raven Mills (Sunbrella) has NO stake in 303 Fabric Guard. One of the biggest mistakes we see is that 303 Fabric Guard is not to be confused but often is & with drastic results the 303 Aerospace Protectant! If you get either of these products on Strataglass it WILL ruin it!
These manufacturers have chosen the finest products to give their products a reputation as being LONG Lasting. Taking short cuts on Canvas treatments or glass treatments can cost you big time! Trust me my friend Seth usually has a backlog of about 40 glass replacements to do before spring.
Here are some tips to help you care for dodger glass:
1) Don't touch the glass with your fingers especially with sunscreen!
2) Use only mild soap like Imar's boat soap when washing the baot if you plan to get the windows wet with soap.
3) Do not constantly put your dodger up and down. Nothing destroys a dodger or windows faster than this. If your dodger was designed correctly it should never need to be "folded".
4) Do not let the main sail fall onto the windows when flaking the main as it can scratch the glass.
5) Do not use paper towels to clean the windows they are VERY abrasive!
6) Use only CLEAN microfiber rags (available at an auto parts store) for polishing the glass and treating it or LINT free soft cotton polishing rags.
7) Do not allow anyone to rest their head against the inside of the glass while sitting under the dodger. Hair chemicals, combined with sweat can penetrate the glass and with the sun create serious imperfections in the optical quality.
8) Never use a wash & wax type product to clean your boat or dodger.
9) Learn to live with small scratches. I can't stress this enough. Trying to buff out small scratches will impact a much larger area than the small scratch. Once the optical coating is "buffed away", from polishing out a scratch, it's all down hill from that point forward. Deal with the scratches and learn to minimize them by not folding your dodger or cleaning it with abrasive products. Common sense goes a LONG way here...
