Get the Right Tools for the Job
One of the biggest mistakes you can make when cleaning a Bestop soft top for Jeep is using the wrong products. There are two parts to taking care of a soft top; the first is cleaning it, and the second is protecting it. The first can typically be done with just water, while the second (perhaps more important) part of protecting it will require specialized products.
Remember to avoid using a pressure washer to clean the soft top. This includes a car wash or one you may have at home. A car wash can be most detrimental to your soft top, as the high pressures and rotating bristles can cause irreversible damage and scratches.
You should be able to get most of the muck off with just a regular garden hose, a steady flow of water, and some mild detergent. For any residual stains that haven't been cleaned away by water, you can use a Bestop Cleaner with a soft microfiber cloth.
Once that's done, you can proceed to protect the material of the soft top and make it more resistant to dirt in the future. The final step of adding a protectant introduces an extra layer of protection against the elements. If you carry out these steps right, you should find that your Jeep Bestop soft top has an almost hydrophobic quality for the first few days. The protectant will also avoid the yellowing of the vinyl windows.
It's also important to try and carry out this process away from direct sunlight. Sunlight can cause the cleaner and protectant solutions to dry into the soft top before you spread and work them into the material. This can result in patchy, uneven protection and may also cause stains.
To avoid damaging the soft top, it's crucial to avoid using any solutions or products containing vinegar, ammonia, bleach, or other harsh acids. These drastically deteriorate the fabric or vinyl and can cause the soft top to turn rigid and brittle. It's also a good idea to stay away from sub-standard cleaners, protectants, or gloss enhancers as they might end up doing more harm than good.
The Bestop soft top for Jeep is made to be durable and withstand harsh conditions. However, these characteristics are bound to reduce over time, and cleaning and protecting the soft top helps enhance them.
